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.

1983 G20 Van, 350 TPI, Ported 906 Vortecs, Edelbrock 3817 Base, ASM oversize runners. Reed Custom Roller cam, 700r4, 12 bolt with 3.08 gears, Doug Thorley Tri-Y headers, true duals
