Hi Ray. The main question is....heads. Do you have heads or will you buy heads. If buy, what's your budget?

I have a DynoSim pull on file, 350 bored 0.030", these pistons
http://www.summitracing.com/parts/SUM-17350-30/
garden variety GM 883 heads, Edelbrock Performer RPM intake, 600 cfm carb, 1 5/8" long tube headers and this cam
http://www.compcams.com/Cam_Specs/Ca...x?csid=85&sb=0
Cut the block decks to 9.012" block deck height and use GM 10105117 head gaskets. Makes 380 hp @5000 rpm's and 430 ft/lbs of torque at 4000. Nice, cheap little street motor that will run on pump gas.
