383 stroker LT1....

I am currently preparing for a 93 LT1 stroker build. After researching cranks I found out that determining crank "Bobweight" consists of taking the total rods and pistons weight, then taking 50% Reciprocating Mass and 100% Rotating Weight before drilling the holes and setting bobweight. I'm thinking of getting an "unmolested" 4340 forged steel crank to work with. And after determining bobweight balance again with an aluminum flywheel with the hub/balancer on the front too. I decided to go with ProComp 5.7in. 4340 forged steel "I" beams which are 599grams each with Wiseco (forged in house) -5cc Pistons. I also opted to leave my stock 58cc reverse cooled "Fast Burn" heads alone. I just changed to NSA rockers, beehive springs, GM hardened guideplates, and chromoly pushrods to match my 292XFI Cam. I did however port my intake to match a 58mm Throttle Body.

Stock, 1.94 and 1.50 valves. Mfr is GM I guess? They are serial numbered too. I just can't bring myself to have them ported, yet!

There is nothing special or rare about those heads, by all means get them ported, seriously. Those heads, stock arent enough to support a 383

O.K. I am going to leave them alone with my stock rotating assembly. They are special to me. I've been thinking about Dart Pro 1 195cc heads?
