Here is a rare and usable (with some machine work/clean up) Pontiac crank shaft. It is the high performance nodular iron crank shaft for 67 and early 68 400's including Ram Air engines. I got it with some other parts as part of a package and I have no use for it. I think someone had it machined and then let it sit unprotected from humidity. Measures .030 under on the mains, .020 under on the rods, but lots of life left in this one with the right bearings. Perfect for a budget build, no reserve.
