Just a quick question. Where can I get information about a crankshaft, I have the part #. The problem is I need to know if it is a steel crank and not a cast crank before I buy it. Thanks for the help.
That crank is a late model, 1 piece rear main seal, forged steel crankshaft. Probably out of a medium duty truck. Make sure that the seller will refund your money if it does not magnaflux ok, as the vehicles they are found in usually put a lot of stress on them Also, they are prone towards having excessive rod side clearance. Make sure you can have it checked before you pay, or that you can get your money back.
Hope this helps,

To obtain good information on crankshafts get the book "The Chevrolet Racing Engine" by Bill Jenkins. The book has all the pictures of any factory forged smallblock crankshaft with part #s. You can also get crankshaft forging/casting ID #s from an engine bearing parts book. Try your local automotive machine shop.
