Iv'e done searches and cannot find the exact answer so here goes. On a 383sbc I have figured out forged cranks are internally balanced, but for a hot street car with max rpms 5500-6000 do I need a forged crank? I want to go with forged rods and pistons for durability. I currently have eagle SIR I beam and KB hyper and lost no 5 due to improper ring gap I believe. I would love to retain my crank with new rod/piston combo, that way I can keep flywheel and current balancer, is this possible?
