340 For street duty

Your 2 unknowns will be;

Compresion, pump freindly @ or under 9.5-1 with an iron head. 9.0-1 will do fine.

Cam;

I can see one as mello as 218 intake duraton on a split duration cam, (1800 -5500 or so rpm range) as much as 230 intake duration on a split duration cam. Possibly slightly more, not much for the way I like the car to run.

You'll need to finialize this one with some reading. Good ideas have been made. The mentioned stall and gears tend to narrow it down abit. seems more like an inflexable dimention added on to the task.
