COMPSTAR – SMALL BLOCK GEN III HEMI
Every aspect of this crank has been meticulously engineered. It starts up front with a post that is dual keyed to securely locate supercharger drive pulleys, and ending with journals that are super finished. For ease of assembly, rod journals are standard SB Chevy diameter and width. Counterweights have been profiled for 6.125 inch connecting rods.
Compstar Hemi cranks are manufactured from 4340 steel and range in stroke from 3.800 – 4.080. Also for improved crank case ventilation and reduced weight, main journals are gun drilled.
