Stock Crankshaft Material
 

What is a 01' LQ4 6.0L crankshaft made out of? I know there strong, but are they cast, steel???

Cast. Who did the machine work on the engine in your sig? I'd like to check the car out sometime.

My motor wont be built till this winter. Engines Unlimited, right here in Strawberry Point. He does all my machine work, and he have an engine dyno.

Cast? Really?? How can they be so strong than???

It is CAST....Nodular Iron

^ I was just about to say.

Will support good power, the issue you will see is either pistons or rods failing before the crank does.
