Not to be a wise [censored] but they all have steel cranks. Wether or not it has a cast or forged steel crank depends on the original application and year. A 70 LS6 4 bolt main has a forged steel crank. An 88 454 4bolt main from a suburban doesn't. 

Would need more info on the engine. Also, if it was rebuilt someone could have installed a forged crank back in the day.

ya thats what I should have said ,was wondering if there is some way to tell if the crank is forged or not by the motor no. Thought that i had read somewere that there were no 4 bolt mains in 70? thanks. Does anyone know of a site to help decode these nombers?
