seriously though. im looking more into the flow design. not nessicarilly cfm. but swirl patterns, fuel atomization, peak hp vs average hp.
legit differences in design.
the pushrod design cant be that bad. the quickes cars on the planet use pushrods(top fuel dragsters)

yeah but consider their displacement. thats no joke. 15:1 on a 440 c.i engine is ALOT! Then you strap a blower on top of that and run ungodly high octane.
but yeah pushrods arent bad, its a different way of doing things. Ferrari ran pushrods in their 2003 F1 car so yeah its not a "bad" setup.
I prefer DOHC cause thats what i grew up on and I find they are easier to work with and simpler. Many people think otherwise.
Also as far as flow is concerned, I dont think pushrod or OHC is as important as the port shape.
I think push rod VS OHC determine how fast the valves are opening, and how high you can rev.
