Ok. My original plan was to build a 355 and feed a small shot of nitrous to it. I acquired a sbc400 yesterday. It is 4 bolt block (i know i know the main webs are supposedly weaker, let's not get into that arguement). It is @ standard bore and my machinist said it will clean up @ .020.

I want to run with good power on this thing. I am curious about strokes and things because I haven't studied up nor do i know a whole lot about 400's. That's why I'm asking here to the people that do know more about the 400's. I don't have any crank/rods/pistons all i have is block and heads (was just going to freshen a pair of 72/76 (i'm not exactly sure what they are) cc heads and drill the steam holes). I can get the metal (oil pan, timing cover) from my shop because we have a few lying around. This will be mated to a th350 with a shift kit and a posi rearend. Please help me on this issue because i'm getting a lot of money for graduation and this is what i'm going to do as a graduation present to myself.
