My grandpa, the original owner of the '65, came and picked it up today and took it to Statesboro, GA. He took it to the guy who restored it before my dad got the truck. He told the guy (Freddy) that he didnt think we put the right rings on, because there was no "lip" on the tops of the cylinder walls, and Freddy said, " I know they didn't put the right rings in because I remember boring this thing out when i restored it." The answer to all of my problems i should think. Still, it was my fault for not miking the bore... but lesson learned...
