How's your cam ??

[OLD...BILL]

Please tell me about your cam, and why, Make, Grind,the good and why you like it. ... My engine is 4" crank 3-5/16 bore, with all the bolt on stuff. NEW Sharp heads 2-2 intake w/94s; Red headers, the car is 39 fordor, three speed 29 tooth, 3-78s rear, just a dally driver. want a good low end,off the line cam ??... thanks Barner's

[Mick/mo]

Isky max 1. Just works good. 48 ford 3/78 gear. About same as your set up. I also have a light flywheel. Works good on the street.Speedway mtrs.

[flatjack9]

Winfield SU-1A in a 276 engine with an aluminum flywheel in a 39 coupe. 3.70 rear end with an Ford aluminum OD trans. Lots of low end. Can start out in second gear. Nice little lope at idle, sound very much like the L-100 cam. Best low end you will get is with the late Merc or EAB Ford cams. Doesn't have the sound though, if that is what you are after.

Bill:

Which ever cam you choose, make sure you clay the heads after installing the cam.

If I recall, don't Sharp heads have an usual shape to the exhaust side of the chamber?

Picking put a cam is a tough decision. Good luck.

[GoCatGo]

Hey Old Bill,
I have an 8BA with an Isky 88 full race (320 lift), and I loved it, untill I just put an L-100 in my other flattie. (375 lift) The L-100 sounds way more "cammy" and pulls very hard at all RPMs.

It's hard to believe a person would have a Flathead as a daily driver, but if you d then I'd stick with the stock cam. If it's a street rod then I'd go with the L-100. The 77b is almpst a stock grind and the Max#1 is a wast of thime. might just as well have the thrill of the L-100 and it's cheaper. IMHO

Literio. It was ground back in the '50's in the North East by Literio. Some of the hot rodders & racers called him the Isky of the East.

Cam Tech. in Florida is currently grinding it on your core.

If you want, I'll try to find their contact info.

[Tom's36coupe]

Crower 3/4 race cam from the old Motor City Flathead (mark kirby). If I were to do it again I would go more stock. My specs are: 383 lift, and 250 duration, very big cam, fun but at idle about 600 rpms the car sounds like its going to blow! I have Edelbrock heads, twin holley's , merc crank and about 260cubes....3.55 rear gear and 3 speed with 46 gears. Low end suffers until it gets going, then tons of fun and people tell me, What the hell is under the hood!!!

From the description of the desired end result there is only one or two cams that can actually fit the requirement. First would be a stock cam and second would be the Tilden Tech 8CM Plus cam. Any of the others which have been mentioned in the responses here will take you in the opposite direction from your request.

[JM 35 Sedan]

Hey Old Bill, I have the Literio 100 (L-100) in my warmed up flattie that sounds a lot like what you are building. I have a 59a block bored 3-5/16", 4-1/8" stroke, 1.6" intake valves, adjustable lifters, Offenhauser 425 heads, PM7 intake w/2 97's using Uncle Max's own design SS connecting linkage (good stuff), Fenton headers, full flow oil filter system and more that I can't think of at the moment. Although this car will be driven frequently, it will not be a daily driver.

I've got a late merc EAC cam in my 8BA, bored .060 over, weiand 8:1 heads, Weiand 2x2 with 2 97's, old Mallory DP, W headers to 1.75" straight pipes... It sounds great at idle, choppier than I'd expected, and pulls great through all the gears.

[Dennis/Arkansas]

A fellow Barner, Richard, sent me a very nice audio recording of his engine running with an L-100 cam. He gives the specifics of the motor in his email. Since I can't post it here I will be very happy to forward it to any who desire to listen to it. Please email me at [email protected] and I will send it to you. Dennis/Arkansas

Should be marked along the cam somewhere. .325 sounds like the good cam.

Hi JWL,
in your book you write about a cam being too small or too big.
What is the max displacement for a stock cam before it gets too small ?

I can`t see a EAC cam feeding a 304ci Flathead even at lower rpms...

Michael

[JWL]

When I wrote about a cam being too big or not big enough it was a reference to the desired RPM level at which the cam design operated most efficiently. Although there is some truth that a larger engine can run with a longer duration cam, it is basically true only because the added displacement helps overcome the poor performance at RPM below where the cam duration is suited for. It is not really a matter of properly "feeding" a given size engine, but rather, a matter of having a cam designed for top efficiency in the RPM range desired.

The Merc cam should be marked 8cm or 1cm & the EAB will be marked EA and sometimes stamped E on the front.

[Lyle]

Hello I have the 53 Mercury cam. I found a article on the net. Can not remember where. That said that Ford spent a lot of money and time to develop the late model mercury cam. In this article the author said that this can was probably the best all around cam. Does anny one remember or concur with this statement. I can't remember what years I think the 51,52,53 were included.

OK, wait. Can I clarify: Is it the '53 Merc, the EAB or both models that are the "hot" stock cams?

Thanks .

Tom - where did you get your specs for your camshaft? I bought a 3/4 MCF cam from Mark back in 1994. At that time, the MCF cams specs were as follows: (According to the June 1994 issue of Street Rodder Magazine, pg 135)

Grind Type Intake Exhaust Lift Duration

3/4 29-72 72-29 .370 282 Degrees
7/8 29-72 72-29 .390 282 Degrees
Full Race 28-73 73-28 .420 282 Degrees


The reason I ask is that I ran this cam from 1994-1996 and for some reason
I cannot remember why I switched it out for a 260F Schenieder cam. I was measuring the lobes and there is a .015 difference between the exhaust and intake lobes. Mine is marked as being a 3/4 MCF. I dont have a dial indicator to mearure the life but I measured the lobe itself and subtracted the heel on the opposite side. I came up with .391 exhaust lift and .376 intake lift. Seems like a have an 13/16 cam??

Anyone have an idea?

[deuce lover]

In my 36 coupe I have a Potvin 3/8 super in my 59AB. Gross valve lift is .375,duration is 280 degree.Nice sound & lope .3.55 rear end gears.Couldn't be more pleased.

The Potvin 3/8th is the cam I plan to use as well. Glad to hear you're liking it.

It was highly recommended by Bill Jenks (RIP) and the one he ran in his own cars.

[Ol' Ron]

Chuck Steevins
I'm not sure which Ron your referring to but I think the 77B is the modt useless cam on the market today. It's basically a stock cam for $200. Fore that kind of money you can get several better cams depending on application.

[robert dick]

i'm running an L-100 in my 258 flat motor, Brockman steel packs for mufflers, even makes the Chevy guys take notice when idleing bye, plus it pulls like crazy in 2 nd gear.

[Tom's36coupe]

I got the specs off of my cam sheet from Crower, Mark told me way back when that it was a great cam for mid to high performance. I think they must have used it on some of their larger cube engines?

[49flatty]

Tom - Did Crower make all of MCF's cams? The measurements I pulled off mine don't match the printed specs in the article either. Crower does not even list anything for the flathead either.

[Tom's36coupe]

I still have an old MCF catalog at home, will check it out after work tonight. I remember when Mark sent me the cam, and springs that the crower was in a box with their name and part number. I did not save the box, but my friend who helped me with the install suggested keeping the cam spec sheet. Will look tonight to see what it reads. I know Mark is working with shadow rods here in Michigan on the french flatheads but have not heard much new lately. His new site is www.motorcityspeedequipment.com

Do you know how I might be able to get ahold of him? He might have some insight to the mystery cam specs. Thanks!

[Tom's36coupe]

If you go to the motorcityspeedequipment site I think there might be a way to contact Mark. Always was very helpful to me and when I met him he was very down to earth. His heat attack almost killed him, and he said sometimes he wished it had. Lost just about everything after all of the expense of the hospital care. Hey, I found my Crower timing tag, it reads: part number E-33794, grind number SPL 59 A Early 262 duration on intake and exhaust and .383 lift with 112 lobe separation. Good luck in finding Mark, I am sure he will have some good information for you.

Anyone willing to compare these three ? I'm looking for something hot and fun to drive, cool sounds also, but as streetable as possible. Will be driven often but not daily.

I came down to these two. Could someone compare them ?
How many mods do they require ?

Welcome. I have a Winfield SU1-A in my engine. I like it a lot. Similar to the L100. At an Auburn meet I was able to have a side by side idle comparison with an L-100. Sounded the same.

[Ol' Ron]

I think the 1007B and the L-100 would work very well in tour engine sounding similar. I never ran the L-100 in a stock car but several of my friends did and they were c avery good running cam. I have one in KGS engine, sounded pretty good on the Dyno.

[mercjoe]

Thanks Ron, so both cams should do a good job wihout major mods ? I mean multi carbs, headers or heads ?

[Lawrie]

I can give feedback on a few cams, one in my 33,std bore 21 stud engine,has the stock cam,it is one nice motor and a pleasure to drive,
The other 33 eng has .060 overbore,and a late model 8ba cam I modified to fit the 21 stud eng,again great to drive,
Our front engined dragster has a new Crower roller cam,my boy spoke to Dave Crower and he made it special for us, this has pushed our dragster to its PB the other month at 9.40 @ 140 mph
If I could work out how to post pics I could show our dragster,But its in my album,
Lawrie

[Ol' Ron]

Lawrie, that's the best cam ever designed for a Flathead, 9.40 and 140. I think that's just great, I bet allot more went into the engine than just the cam.
Take care Ol' Ron

[mercjoe]

Hi Bill, thanks for the welcome.

I have nice 46' Ford 59a sitting around which I plan to use on my next project, a 38 Ford coupe. The engine is not running, all stock and we'll be getting a full rebuild.

My only experience with flatheads was my 50 Merc' 0CM which was absolutely stock. I didn't have enough time to play with it.

I will overbore (still don't know how much a flathead can or should take), no Merc crank. Regarding parts I have a 3x2 Edelbrock intake, spare carbs, headers and hopefully a new cam when I decide which one to use. I would really like to stick with stock heads.

Isky 1007B and the L100 seem to be a good choice. Couldn't find specs but the Clay Smith 5-T grind might be on the same league.
I have lots of doubts though, some say they are not streetable, some say yes they are, low end power drops, some say they pull well at all RPMs.

I was thinking about using 3 carbs but I really don't want any tuning headaches, specially considering this will be exclusively a street car.

To make it short, I want to keep it simple, want low and mid range power for the street, good idle at reasonable RPMs, and last but not least I want it so sound great.


Thanks again Bill.

Ron, so you definetely recommend the L100 for street rod. You said some friends of yours used it on stock engines. Which mods would you recommend with the L100, I mean carbs, heads work, etc. ?

I'm really sorry for my cam related ignorance... , hopefully I'll learn some from the ones who know.

Thanks !!

[Ol' Ron]

A few years back I built an engine for Paul Howard (AV8 Paul). It was a 37 21 stud block with all 8BA innards and an L-100 cam. The 37 heads were milled and cut for valve clearance, but we only got about 7.5CR out if our troubles. Paul used a PM-7 with 2 97's. Got 22K miles out of it before he spun a rod bearing. He coined the phrase "Smiley cam" and every time he fired it up he got a big smile on his face. Got stopped in AZ for going 105 mph, not bad for a 239ci 21 studder.

Most cams kill low end torque and one as long as the L-100 kills even more, so increases in CR and displacement make up for this. There are enough L-100 out there in every kind of application that we have to look at WHY? it runs as well as it does. At present it's undergoing economy tests and getting great fuel mileage as well. There are a number of people responsible for this, I'm not the only one involved.

EVERYONE; Please go back to page one and read my opening tread, and where I mis-spock about a daily driver, and read #6 Ol' Ron about putting a stock cam in my engine, we-er talking about two different engines, and I was not very clear where I jumped from "mencjoe's" engine to my engine, hold on Ol'Ron I'll go with you and get my eye balls fixed too. and I do look forward to reading your treads, and learing from your knowhow for a longtime to come, and make our flatheads run better.... AND ... PETE ....I started this tread, asking about cams of today, and you ground the Isky 1007-B thats going in my engine.,,, and daily driver.... NO ..its will be now and then driver. with 2-2s... 276 inches, in a 39 fordor w/columbia 3/78s... I am a big,old.geaser,broad shoulders, I can take it when Iam wrong. and I did mis-speek, but I do not call names....and Ol' Ron, sorry I got you in this, ..but would you realy put a stock cam in my engine, with 4inch merc crank and all the good ( Sharp ) bolt ons??.... AND ..OLD...BILL... OPENS ANOTHER CAN OF WORMS
NOTE; I stand by what I told Joe to put in his engine, anyone else want to jump in here and talk about 3-2s on his engine and dose not want a tuning problum ??

[Lawrie]

Ron, you sure are right,a lot more went into the eng,with help from you,JWL and walt.
I had a mate who had the lazer surgery on his eyes,He was super impressed with the result.
Best of luck.

[Ol' Ron]

Love them Flatheads, wish I was younger, so I could play hard.

[Walt Dupont--Me.]

For you guy who love carbs, I'm running 4 97's on 276 with around 9.5 compression and reground track cam about like an L-100. It's in my 40 coupe with T-5 and 9in. 3:50 gears. Carbs were set up by Mad Max. Runs great, 17-18 mpg around town and secondary roads. Haven't been on a long trip on pike. Spark plug run white. The trick is setting them up right. Walt

[S.Duncan]

Ron;You mentioned in another post that there was a blower version of the L-100,do you have any personal experience with this cam? As always thanks for your feedback.

[Ol' Ron]

No the engine hasen't run yet, we just got the blower assy and the plan it to put it together this winter. I Hope. I have the specs someplace and will post them.

[John Kennedy]

Good thread here. Great info and ideas.
Since I'm building a daily driver with a mild flathead, sounds like the L-100 is the cam for me.

Ron - good luck with those eyes!

[mercjoe]

Bill, I don't think he told you to use a stock cam, it makes sense to keep it as simple as possible on a DAILY driver. I think that's what he meant.

And that's why I'm so doubtful. Even I won't be using that engine on a daily basis it will be a street car, so I would like to avoid any hassles but at the same time having the flathead built as powerful and fun as possible.

I'm running the Potvin 425 Eliminator. I couldn't be happier with it, but I'm sure some wouldn't like it. It idles high-900 rpm now and still sounds REAL healthy. I may be able to reduce the idle further. But, the throttle response is nothing short of amazing. It pulls from about 1500 rpm HARD. Not a good cam for an automatic, I'm sure. The engine does not sound at all like a flathead anymore. Probably because of the center exhaust port dividers. If you start it up with the hood closed for someone, the last thing he would think of is a flathead Ford. The engine literally explodes to life. It's loud thru the 24" Cherry Bombs and really loud with the open headers
Pete did a great job.

Cool. Ground it on a cast iron stock core? I think I recall Pete said it was OK doing it on these.

May need to send one out to get done up.

Love those cams!

Get a video of the Eliminator!

This one is pretty rowdy for obvious reasons. I can't figure out how to get this to embed so here is the link: https://www.youtube.com/watch?v=WLFTO0Bx9-E

That engine/cam/fuel mix just screams NASTY !!

Im running a kustom ground Tatom blower cam in my 8BA at 289ci.

HAULS !!

Unfortunately, the 8CM Plus cam currently exists only on paper. I've been trying to get Bill Stipe at Specialty Motor Cams to make them. Perhaps we need some sort of grassroots ground swell of requests.

[Junknshit]

Anyone here running a Tatom built motor?

[Ol' Ron]

Larry
After racing drags as well as stock cars for many years I thought I had a sense about cams. I do not profess to be knowledgeable in cam design. I've known David Generous for over 30 years and he's been very helpful in exolaining the ups and douns of camshafts. At this point in my engine building efforts I;ve been trying to geet more efficency out of our Flathead and am building an econo engine specificity for fuel mileage, without sacrificing performance. So far we've succeeded in puting a 276 ci engine in a 3800 lb car and getting exelent mileage. It's at it's best right now with 21.5 in a 50 mile route that consist of 66% local roads and 33% interst5ate. Now here the RUB, it shouldn't do this , the engine has a Cam techniques L-100 246/235 at .050 .360 net lift. The economy engine is similar but with an EAB cam.
There must be a reason why this cam performs as well as it does. One other engine in a 37 4 dr seadn gets 21 mpg on a trip which des not have any interstate driving. I feel I could get more from this engine if we removed the 97's and installed a better distributor, but the 42 crab dist id performomg well so far.
I've plotted a few cams before and I have a Howard M-6 which may work quit well from a mileade point of view.

But we hot ridders like the sound of a hot cam.

Ol' Ron

[Ol' Ron]

That should read M-8. sorry.

I gotta say best thread I have seen/read in too long. Great information. I really wanted to run the potvin eliminator, but many said it would wear my lifters.I dont know if this is true I would like to hear one idle at 900rpm not that I doubt it just would be awsome before I decide to install one

Wear your lifters?????????
HA HA HA ROFLMAO......

[flatheadz-forever]

Haha ok I worded that wrong. I heard that if you let the eliminator idle to low or too long it will wear out your valve train. It is sometimes hard to tell who is b.s. you

[Straightpipes]

I've torn down quite a few flatheads and ran across some reground cams that I could never identify. It seems as though there were many unknown folks grinding camshafts for a lot of uses in the 40s and 50s.
Has anyone ever tried to compile a list and ID markings? Especially for the lesser known brands.
What brings this to mind is that I just pulled a few out of my shed and have one marked "L 49". Haven't measured it yet.
Oh, by the way( Ol Ron if your listening) I put an L-100 in my 8BA and never bothered to look. Is the L-100 marked by cam techniques?

[Ol' Ron]

Unless somebody is copying them? Yes. Where did you get it?

I'AM IN, just spent some time with your chart and I went back and read John's tread on page 2-#28, and the 8CM, with its low duration,and good lift. Would be right for the good low end and off the line, torque, we want for the street. The other question is "what is the idell" going to sound like?? Like Ol"Ron we love a hot sounding flathead ...So how do we get this cam ground, out here where we can run it ... And how do we contack Bill Strip at Specialty Moters Cams ... Like I said up top I'AM IN ....and thanks for all the nice things you all have said about this tread "HOW'S YOUR CAM" ??.... OLD....BILL

[Cartravel]

I don't know if any of you have run across Harvey Cranes website - http://www.harveycrane.com/duration.htm. Lopey idle is a result of valve overlap, the degrees both valves are open. This spells a loss of low end torque. Of course, you can make up for that loss through other mods.

Can someone post the 0.050 and seat timing numbers for the L-100 cam? I've seen some of the numbers, but no lobe separation.

[Bassman/NZ]

This is such a good thread, I'd like to include lifters in it as they are part and parcel of the cam setup. I've read posts here and on the Hamb stating that modern Johnson replicas are rubbish. I dont know if that's true or not..... would anyone care to throw their 2cents in? Are there viable lightweight alternatives? Does lifter weight play much part in a flathead valvetrain? Here in New Zealand, back in the days when flatheads were common at racetracks, guys used to build up valve stems and/or lifters with brazing because adjustables weren't available here. Is this still done?
So many questions, so little time............

Adjustable lifters have gotten a bad rap in the last few years.
A large percentage of it is deserved...Everyone has stories of them lasting forever and others say they had them back off almost immediately.
Most are probably made offshore now so who can know?

I advocate using stock hollow steel lifters and welding the valve stem if they are too short....It takes longer to do but you only do it once and they never move. In high performance (not street) engines adjustables have no place.

[40 Deluxe]

How about modern cam designs in a flathead? I'm thinking of the "Thump'r" series cams from Comp Cams. Has anybody run one of these? Are they for 'show' or 'go'?

[Tim Ayers]

I'm interested in that as well. I'm always leery of a cam advertising "the sound" vs. performance.

Almost makes it seem hokey.

[Cartravel]

The L-100 looks similar to an Isky 400Jr with 3 or 4 degrees of advance.

If you are concerned about valve train weight, you can find some information at http://www.tildentechnologies.com/Cams/CamSprings.html.
You can't beat the stock lifters for weight.

[lonewolf]

Does anyone have an audio clip of the isky 1007b

Ron,Why do you find it hard to believe someone would drive there flathead as a daily driver. I seriously drive my 37 to work(Honest Charley Garage) everyday, and it's had a knock for over 3 years.

[tiquer]

Back in the day everyone drove to work often in a flathead powered car or truck. Never once was i Left stranded by my flathead.

[KiWinUS]

Great thread
To da top

[Ol' Ron]

8 Years ago I had a different outlook on the need for that radical cam sound that the l-100 gave. In a large displacement engine it works just fine. However my present 280 ci engine in my truck has an EAB cam in it right now and the torque makes these Green mountains feel like the flat lands of Nebraska. I guess I'm just getting old.

Getting old could be the reason but I suspect it has more to do with not picking a cam because it sounded good on YouTube.

[Flathead]

296" flathead, 41 Ford coupe, 2 deuces, 400jr cam. Good idle and instant throttle response that surprised a lot of people, some with overheads.

does any of you have any specs on Engle Camshafts , I talked to Engle a while back and they said they haven't ground a flathead cam in a number of years, and had no spec's on them. I am trying to identify a cam I think may be an old Engle grind.

where is Old Bill? i hope he is ok!

[40cpe]

That's a good question, he was last on the Barn in Dec. of 2016

[Kahuna]

Pete would know for sure, or JWL, but what about using the profile of the latest 53 Merc cam & adding some lift to it. Somewhere in the .375"+ range. I bet it would be a real good performer & still have a stock idle & give good mileage?
Just a thought.
Oh, then have it dynoed in New Mexico to show 300 HP
Jim

[Pete]

An early Chrysler 6 stock cam (flathead) had .375 lift.
This was tried in flathead Fords a few times for "stock car" racing
but was usually rejected as not being stock for the same type engine.
It did help slightly.

Oh, and 300 hp is relatively easy to attain from a flathead Ford with a blower, but try doing it naturally aspirated.

I've wondered the same thing. Last time I got a message from Bill was just prior to the 2016 EFV-8 Club WNM in Bakersfield, CA. He told me he could not make that meet, and his brother Charlie would tell me why when I saw him at the meet. Well, I never saw Charlie there, so never found out the story on Bill. I've tried to email and PM him several times over the last two years, but get no response. Doesn't sound good to me.
