Dart for sb2....but the sb2.2 works w a stock block..And another thing 1000+ is old news,there makin a bit more now.
Alot of engine builders just either dont have the experience w the stuff .Jeremy aka Extreme engines and ten speed believe and have told me the p7 and sb2 are almost indenticle,however tenspeed believes p7 is a little better and 440ci sb @ 8500 will exceed 1000 hp NO PROBLEM.I also know the p5 will make power also but needs 9500rpm.
