Ok so I did some research and saw that there was no A code 289 produced in 1968. Yet I have a flat top piston. I originally did not see any stamping on the pistons, but I was looking at the center of the pistons. I started to suspect the I was wrong about the piston, so I took a wire brush a gave a piston at top of the bore a good cleaning. Low and behold is see its stamped 273AP and .040 near the top. So its got Sealed Power 273AP cast pistons and bored .040 over. This is a rebuilt engine. No wonder its in such good shape. No clue on how many miles it has but I myself have put at least 10,000 on it over the past 2 years. Thanks guys for the help on finding block number and etc.. I am curious now as to what kind of compression ratio this thing has with stock 1965-66 289 heads.
