Say for instance, one was going to build a fully forged 383 small block. Nothing crazy....whatever that means.

It would run a SuperRam
Probably a 219 cam with 1.7 (0.595" lift) or maybe a custom 224/230 ish with similar lift.


What flow numbers should I be looking for?
What would 270/190 @ 0.600 lift heads yield power wise?

Any ideas? Or are there way too many variables.


**EDIT**

Oh, definitely budget minded.

Something around 190-200cc, like a Dart Pro 1 or a TFS head.

Jerry. My old TFS heads might be for sale. They are still new, and great quality. I woudn't do 1.7's. I asked TJWONG about 1.7's. He said it wasnt a good idea. Idle suffers, and its harder to tune. I didnt think it was worth it for maybe 10 HP. Whatever you do, don't buy one of those $1500 383 shortblocks.
