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.

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.

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

Excuse my ignorance.... what brand is an L100?

[jdl]

I have never used a L100 cam but Ol' Ron calls them...
The Smiley Cam They must be good

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.

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!!!

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?

L100 developed by the leitho bros way back now is being ground on the east coast beautifull exhaust note & plenty of grunt

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.

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.

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.
