Pulled the engine out of my 79 Corvette, and the crankshaft meets all the aspects of being forged. I even looked up the casting #'s (what I could get) and that also said it was forged. Why would GM drop in a forged crank into an engine that isn't even making 200HP?

Fewer warranty claims and a surplus in stock would be my best guess.

My guess is its a L82 and thats what GM built them with from its introduction in 73 all the way until 80.

My 160hp 305 had a forged crank and 4 bolt main caps from GM.

While there is no reason to have a forged steel crankshaft in an engine like that, the fact that it was assembled that way just goes to show that nothing gets wasted during manufacturing.
