big block forged crank. No unusual wear. 100 plus the ride

was out of a baja with 502. 4.5 stroke

Ya for sure but could be anything. lol... Certainly doesn't look like a 4.5 stroke either. Remember the thread a while back I think hoggie roll posted a thread with a 4.5 stroke 9.8 deck 454/510 ci or something of that nature. Not my idea of endurance unless it's going in a tall deck.

just what the guy told me. Got it off powerboat swap shop. Ended up getting two new cranks for my project

I think you can measure from crank main center to rod main journal center and X 2 would give you stroke. Don't quote me on that though. Be a good deal for somebody.

Ok yea guys I was totally wrong. It’s 91 up forged 454 or 502 one piece rear

My apologies
