I judge it by quality and durability. The Turbo variants of those engines readily support 800hp with stock bottom ends.

I think pushrod engines in many ways are superior- far more reliable due to far fewer moving parts. They also cost vastly less money to rebuild as well. Most OHC engines also use belts instead of chains, which further hurts their reliability.

The (real) SB Chevy, 5.0 ford and countless other US Pushrod V-8s are as strong, reliable and long lasting as any mass produced automotive engine mankind has ever made.
