I recently purchased a lot of Chrysler parts from a guy who claimed his grandpa was a NASCAR racer. Looks like a have a 355 cu. in. crankshaft for a small block LA. I have another crank that looks just like it that came in the lot i purchased, but I can not confirm its specifications yet. What do I do with this crank? I really don't have a use for it. What's it worth? Who can use it?
