what about a 383 stroker??

If you have a buddy that does good machine work thats worth a bunch.For the heads some people dont like the Edelbrock heads. But on my 451 they make 550 hp and are out of the box except the springs. I went with a dual spring set up because I'm using a Racer Brown cam. It has fast ramp speeds to take advantage of the big diameter lifters. My machine shop said they could make my small chamber heads flow as well as the Ede's after almost $800 bucks of work they said it would be at least $1800 and they wouldnt flow as well. I trashed them and went with the Ede's at 1300. If your car is a streeter just go with a flat top piston and have it set a 0 deck height. You can mill the aluminum heads some or have cometic gskts make you a set of thin gskts. But you want at least .040 piston to head clearance for saftey and good quench. If you are making a racer get domed pistons. Mine are 9cc domes and make 11.5 with 0 deckheight and stock Ede combustion chambers. But you need good gas for that compression. Aluminum heads are 40 lbs lighter than Iron and look cool
