Quote: Not gonna happen unless you go with a stroker setup, which IMO does not fit my definition of a 'budget build'. You can however get 375hp out of a streetable, stock stroke 360. I'm not saying the 425 can't be done, however you'd have to spin it to 7k and run a monster huge cam in it which would not be streetable.
I totally disagree. High Performance Mopar mag. did a build up several years ago and got 430hp from a mild 360. Pump gas, ported smog heads, Thermo carb, and stock crank. If you want I can look up the exact specs.
