Safe max HP for a stock frame

[Talkwrench]

This 34 is not boxed most of the mounts are bolt on and has been running a blown 350 C*8V [500 +HP] since back in the 80's I have seen it run a flat 11 seconds, lifting the left wheel completely off the ground.. Its currently running a tunnel ram as it was driven all the way to Tasmania and back, many times it has crossed our continent [with the blower] to national hot rod shows. It belongs to Nev Anderson , he is one of our founding hot rodders here in Western Australia..

My first thought is a late 50's hemi - max. 354 cu in. Inspiration comes from Don Garlitts. His museum has a couple of 40's in his personal collection in Ocala. They are stunning.
