I have a lead on a complete, yet disassembled 400 engine(carb to pan). Supposedly it's a 76 with 78,000 miles that ran fine when pulled. It's disassembled, oiled, and bagged....and I trust this description as far as I could throw the engine. I'm limited to a pair of calipers, as my father has my other stuff in Florida. The guy wants $400, and all I'm really interested in is the block. This seems like a descent gamble to me percentage wise. Sound like good odds to you guys?
