It was rebuilt by a machine shop some unknown...a long time ago It has 60 over pistons but, I didn't mess with the crank. I've misplaced the tag but, I think it read Wilton CA. I want to make sure I know what it is if someone asks. It is a RG with 5 freeze plugs. Block is 2806830-3 and 09129: and W. The stamp pad has F225 T and a real faint 1. Can someone break it down for me. Thanks Craig

According to the links below your engine is a 1970. I believe the T stands for Truck. At one time I heard that the truck cranks were shot-peened to relieve stress. Perhaps Doug or Dan S. can confirm.
