I don't think I can help much with a crankshaft, the shipping from Utah to South Carolina, FedEx is $114.00 (based on the crank being 85 pounds and 40 X 9 X 9 inches)
Suggest you look online, I found a re-manufactured crank for $140 plus shipping that was all ready machined and included bearings.
Of course, if I can still help let me know.
Thanks for the offer. I managed to find a few 250ci engines in my area. Not sure why they didn't pop up on my initial search. Anyway, it might be better to buy the whole engine just for the crank. Thanks again.
