Theres assembly lube all around all pistons and also around the crankshaft which makes me wonder if it really did get rebuilt. The person i bought it from says he has a reciept that shows the work that was done, which was new rings, rod and main bearings. The head casket from the sides also look like they are brand new, so im going to pull the heads off and see if they are n/a or tt pistons. Hopefully they're tt pistons because I can get a set of tt heads quickly and for a good price.
