hey guys. i have a 71 dodge dart i just built another 383, with 440 sources heads and 30 over keith black pistons. the compression is at just over 10 to 1. do to being lucky with the 80 cc chaimbers lol. also its fully balanced and blue printed and all that was advised for me to use with this combo was comp cam 507 intake and 510 exhaust cam. i wanted the 528 lol but anyways im dropping it with my 727 and 391 pose. does anyone kinda know what horsepower i might reach with stock hp exhaust manifolds rare ones. and possible times i might run with this set up with micky tompsons street slicks with the ralley rims ? i will find a way to post some pics.... my old 383 was a 9/5 to 1 comp stock with a 509 cam and it didnt run right lol
