318willrun said

two things I know:

1. 904's can be built to take mega power
2. From the factory, anything much more than a 318 4bbl and you'll soon have a slow shifting tranny from 1st to 2nd if ya keep a beat'n on it.

So my question is, "if a person wants to put a 904 behind a 375 - 400 hp 360, what would they have to do for upgrades to make it reliable on the street (in other words, no manual valve body)?
