That's true. They're kind of like a reciprocating explosion <g>. But 
they do demonstrate that you can achieve pretty damn good volumetric 
efficiency with the old pushrod V8s.

Yep. For about 4 to 5 seconds!

It wasn't aerodynamics. In truth, it's not hard to make well over 1000
horsepower with a normally aspirated Chevy V8. The ports and valves 
are
sewer size, and the chamber design allows for at least 13.5:1
compression ratio with little valve restriction. That's horsepower. 
The
engine doesn't know it has pushrods. Hell, the world's most powerful
automotive engines are pushrod engines. Top fuel drag racing engines
now make around 8000 horsepower from 8 liters. That would be 8 litres
to the Porsche boys <g>.
