I have a 400 chevy 4 bolt main(weaker than 2 bolt) that has been rebuilt 30 over mabey 1,000 miles ago. How much power can this thing handle with stock internals. I want to build a low budget sleeper for my 75 nova 4dr and looking between 400hp and 500hp.
No announcement yet.
How much rpm and hp can a 400 small block handle?
