Stroke old 340 or new crate engine

The MP 4 inch stroker crank I have has the part number stamped in the front counter weight....

Scat was providing MP with both cast and forged cranks for awhile, as MP had exclusive rights for them for awhile.

That's what I thought. It has a number on the front counter weight, though it was also engraved over with Ohio's numbers/job #
