flathead on dirt track

flathead 8RT stock except for .040 over bore, cam headers and a 350 holley 2 barrel. I have some friends who seem to think a flathead will rev like a smallblock ford or chevy. I need someone (besides me) to tell these guys what a realistic red line should be. Bobby-- K-nine Racer-- I know that you have the answer. Would you or someone please comment on this?

5000 rpm maybe

 

Tell them to go for it, ignorance should hurt.

5k is a ton for a nearly stock flatty, and where are they going to get an intake that will flow 350cfm.

 

You're wringing a stock flatty out at 4000. Will it go more? Sure. All the way until the tach reads BOOM!

Go to the Ford Barn early v8 forum. Old Ron has built a lot of flatheads. He will tell you what to expect.

 

What to expect is to spend a lot of money to build a loosing combination. You are starting with an engine that made 100 ponies on a good day stock and expecting it to compete with engine that make in the 300+ hp range stock.

Now if you were to get into vintage oval track racing where w you were competeing aginst other flatheads maybe you could build a winning combination.

Here is something to keep in mind, the demise of the flaty as a viable racing engine was the valve in head V-8. They still compete in venues like land speed racing because they are competeing with other flatheads that will not be the case roundy round.

 

the voice of reason

 

Mine has a 4 inch crank and I try to keep the rpm around 4800 tops some times if I have a good lap I might go 5 grand.. I lives a lot longer that way... I have been told that you can turn the 3 3/4 stroke a little more but I have never had one in a race car..

 

But THIS is in no way a stock engine 0.040 over with a cam and headers that the OP is seeking info on.
