Ok, so, Since I got a good deal on a set of hypereutectics, that are flat tops, and 9.8:1 with 64cc heads, I can pretty much do what I want with the compression with various head and gasket combonations.

I am looking for over 400 hp out of a streetable 383 stroker, with oober amounts of torque.

I have 3.73 12 bolt posi, built 700R4, and a stock lock up converter from a V6 vehicle (higher stall, maybe, like 500 to 750 rpm higher than stock)

Basically, can I get power I "need" (want, actually) with a CR around 9.0 to 9.5 with out going crazy with the cam. Like a CompCam 268, or something like that, lumpy, but plenty of grunt around 2k rpm? Maybe a set of Sportsman IIs or Darts.
