4.030 bore with H beam rods.
"The forged crankshaft will have a standard 360 main bearing with NASCAR sized rod journals (1.889"). The stroke is 4.180". The lightweight rods will use lighter weight 0.912" pin diameter and will naturally be full floating. Minimal notching will be required to allow this kit to drop in. We strongly suggest that you use our main bearing support girdle with this long armed screamer. These kits will be internally, race balanced.
