Cylinder heads

[Jim Brierley]

Is Charlie Yapp still making flatheads for the Model A? Or Snyders making performance heads?

Snyders still does , they have a whole table of 2nds in the showroom in Ohio .The seconds I looked at seem to have pits in combustion chamber or areas the didn’t clean up when machining .Not sure how this would effect use ability.

Thanks, I'm not looking to buy one, I'm just trying to get prices so that I don't price mine out of the market. I had been selling them for $650 but the cost of castings has gone up 50%, I'm now doing some of the machining myself in order to keep the price down.
I see that both are out of stock, Yapp's last price was $850, I can beat that, but now I know what to shoot for.

Just to say - I really like my Brierley head.
It pushed this down the beach at 74mph...

Hot, have you done anything else to the engine other than HC head?

Is that directly from Dan? I think Snyder's handled them at one time?

[johnneilson]

Just FYI
Be careful of internet advertising because it more than likely is out of date
For instance you can look at Donovan “D” motors on line with an advertised price
But these have been sold out for some time

I'm stuck at 68 mph. I think it's starving for air - stock intake & carb. I picked up a B carb to see if that will help. Mine is an Antique Engine Rebuilding touring engine. A friend has a dual Zenith updraft manifold but won't part with it. I like that idea because it keeps the gravity fuel system. I bought a pair of Stromberg knock offs and 6v fuel pump in case the B carb doesn't help enough. Of course once I get 70 I'll be looking for 75.

That was directly from Dan, but do check with him on current costs. It seems that some
peoples prices are from older inventory and when it runs out and they have to remake
it the price goes up quite a bit as their cost have also risen. I think you are seeing that now Jim.

I can't compete with Dan's price, and have decided on $750 for a head.

Thanks to all, Jim B

You also have to add in a new water pump. His uses the B pump - his cost for a new pump is $425.

Or use an electric pump?

You still need to buy the pump - do they come in 6V? and then make up the pieces to adapt it to your engine.


This is the only photo of Jim's head I can find on the web. Looks like all you need to buy is a new water pump gasket.

Ported B block, Stipe 340 cam, reshaped stock size modern valves, 97 on a Burns manifold and a Snyders cast iron header.

74 is at the end of a half mile sprint and with 3.27 gears it's still pulling at that...

My head comes with a longer dist. drive shaft because the head is taller than stock. I also suggest buying my ARP stud kit, for the same reason.

I would post a picture of my head but it is too difficult for me on this site.

Here you go Mr B. Mine is number 7014

I notice there is no relief over the pistons.
When running higher than 7 to 1 or so, I would suggest people think about heli-coils in the block in addition to the ARP studs with their washers and nuts. Putting high strength studs in doesn't give you full strength unless the threads in the block can carry the load. Especially, if you are adding a few extra ft-lbs to the torque (65 instead of 55). If you are building from scratch, your engine builder can check the threads in the block and make the call on inserts.
I am sure there will a lot of response regarding the torque but you want to take full advantage of high strength studs for higher compression engines.

Is that aluminum?

I like that combustion chamber design!!!

Full Race - Your signature line is funny. I interviewed with Ford in the 1990's and I mentioned "building what people want" and the interviewer replied that Ford tells the customer what the customer wants. I could not believe the arrogance.
They asked why they should hire me and I replied, "I have worked on your cars, you need me."

I now put a .040" relief over the pistons. .040" over 1/2 of the piston doesn't make much difference in ratio.

I've been racing Model B engines since 1958, and have never needed to heli-coil the block, and I have run 10:1 compression and 6,000 RPM, and now run 7.5:1 and a turbo at 10 psi, with no problems. On my OHV Cook I now have the cylinders 'O' ringed. I also ran full babbitt, including the 'B', rods for many years and the mains are still babbitt. The crank is a drilled for pressure 'C', standard but not new when I first put it together in 1960. I torque the Cook to 70 psi. Top speed to date is 167.45 MPH

Thanks for sharing your knowledge by writing that most excellent book!

Jim,

Can I get on the list for one of your heads?

Most people are under the mistaken idea that they are customers of Ford Motor Company. Ford could care less about input from the owners of their cars. The car buyer is the dealers customer. The dealer is Ford's customer and they have very little input as to what shows up at their door. They get a message that X number of cars are on the way and to have a check ready. Ford (for the most part) doesn't care how the dealer gets rid of the cars since they'll be getting paid for the next shipment they send in a short while. A friend was a PR contractor for Ford. He got us into some of the Ford events they host to bounce ideas off the public as to what they want to see in a car. Those events went from an interview type meeting for the low dollar cars all the way to sit down dinners with wine and professionally done videos and a cozy exit interview. I also did some pre production ride & drives. In the end they weren't really asking what you wanted but if you liked and would buy what they had decided to build. Of course you agreed after all you were leaving with $100 - $200. I got an invite about 6 months ago. It paid $150 for a 1 hour survey in Pasadena (20 miles away). I figured it would stretch to 2 hours and put me in the middle of SoCal traffic so I declined.
