Flathead combustion chamber profile...Q

So much has been learned in the past few years about the combustion process. Has anyone been able to apply that knowledge to flathead design? Sounds very strange for a 70 year old book to used as the flathead "Bible". Look at how much the OHV design has changed in that length of time.

I know the thread is about flow, but combustion quality is equally important.

Wow, did you think of that all by yourself?

 

Hey, Steve;

In the 1001 Rod & Custom Ideas, circa '77, (IIRC, there were also articles on 20's dirt-trackers - from a PopMech, board-trackers, 30's Indy cars, & there was an interview w/Winfield. Included was a lot of info on Eds' heads' chambers. Description only. Think Tom Senter & Kong Jackson did it.

If I can find it, I'll re-type to post it here. But it probably won't be soon... If someone else can copy'n'paste it, that's be great.

Marcus...

 

So much of a flathead's breathing potential has to do with the ports in the blocks, arguably more so then the heads. Bored&Stroked wrote an excellent thread on porting the flathead that may be useful to Stevie.

Here is a cutaway of an early 21 stud Flathead.


Here is a cut-away diagram of the V8-60, similar to it's big brother.


Not the best view, but somewhat useful

 

This just keeps getting better. Thanks for the "Flow" of information.
