Quote: I would build it like a 383. Use the closed chamber heads and get a cam in the 230 to 240ish @ 0.050 range a good intake and carb, headers, and it shoudl be an easy 430/460 hp/tq motor. Compression is the issue and open chamber heads are harder to work with in this regard.
Assuming it's a cast crank you can go up to 500 hp easily. If you had a forged 383 crank laying around I would use it for insurance, but the cast is fine for mild builds...just creates some unique balance issues during the build. No big deal really becasue it is good insurance to nuetral balance the rolling assembly anyways.
Exactly what Im thinking. I scored a single plane weiand intake the other day for $50. I could run that with a 1 inch 4 hole spacer along with the appropriate carb and be set in that department.
Then add closed chamber heads with hardened seats and a good three angle valve job. Then headers and the other typical bolt on hot rod stuff. Windage tray etc.
Looking at cams to maximize low end torque as well..
