i thought 400 hp from a 360 was a mild build,...easy as falling off a truck!!

It is. It's been done with smog motors using only factory parts and under a 9.0:1 cr. I think that it was mopar muscle magazine that had article's on how to get big power from 360 smog motors, cam, heads, etc have to be as from the factory
