Big horsepower 318 builds

If one were to look at the Ford/Chevy 302 video for guidance....... it would appear the path forward to a 500hp 318 is to throw a pretty good wad of cash at it.
Big *** heads, big *** manifold, healthy solid roller cam, etc.

That usually works for most things HP related.
No reason it wouldn’t work in this case.

It’s just that........ most people spending that much...... want more than 500hp as the end result.
