Power advantage between Ford 351, Mopar 340 and Chevy 350??

If you made everything as even as possible, it comes down to air flow in and out with the key to these engines being the cylinder heads.

If you take advantage of our .904 lifter diameter where the other two can not, you would have a good edge in what is otherwise all as delivered stock engines for this comparison.

The Ford Cleveland 4V head is that engines strong point which pretty much buries everyone else’s head. That would be a tough one to overcome on a “A Cast Head.”

Look at NASCAR. How many times were Ford and Chrysler penalized for being too fast? Guess how many times they added weight or messed with their aerodynamics to Chevy?

The heads will dictate the pecking order, led by the 351 Cleveland 4 barrel heads, 340 heads, poor Chevy guys never had a chance.
