Part number is 3967811. In the factory box.
Anyone know exactly what this crank is?
Also what it would be worth.

It's a GMPP part...available for $821 at Flatlander Racing...

"This 1053 forged steel crankshaft has a 3.76" stroke. It is nitride treated to increase journal hardness and enhance fatigue strength. The main bearing journals are cross-drilled to provide a constant supply of oil to the rod bearings. Use with 1965-89 two-piece rear seal blocks. Technical Notes: Main journal diameter is 2.75"; rod journal diameter is 2.20". Crankshaft ID #7115."
