I had bought a short block back in 2000. And it turned out mines actually a 388. Block bored .060 over. Since my motor was originally going into a smogger blazer I got the performer heads. Tho same cc's and runners as the RPM's. Just has the EGR crap. But look at a 383 kit and see with what pistons and head combustion chambers you will need to get the compression you want. I do almost all my parts ordering from Summit and Jegs. They have a few stroker kits, and with almost any comp ratio. They also sell high torque 383's so you can see what parts go into them and buy the same if you like. My motor has seen many parts. Performer EGR intake, Q-Jet, and edelbrock performer 400 cam (214 duration). Then it had Performer RPM Air Gap intake, Demon carb, 230/236 duration cam, and now back to a truck friendly 214/224 cam. Remember the bigger 383 and higher (around 10:1) compression can take a little bit bigger cam. Thats why I used the Performer 400 cam instead of the one for a 350. But the Edlelbrock cams are an old design. Look at a Comp Cams Extreme Energy or Lunati Voo-Doo series which is dual pattern. Probly something with 212/218 duration would be your best bet. But I recomed that after you pick out your rotating assembly, heads, and intake you call or go to Comp Cams websight. They have a form you fill out to pick the perfect cam for your application. Tho you have to answer 100 Q's about your engine (bore, stroke, heads, intake, exhaust), the vehicle (wieght, gearing, tire size), and its intended use (off-road, racing, towing). Also if you can fork out the $$$ AFR heads are the sh1t!!! I would have bought them but didnt have the money at the time and needed to get my truck on the road ASAP.
