Tearing it down

Yes I am putting in a new cam. The stamping on the block looks to be 340. I will check into this after I pull the heads. I did not get to pulling the heads off today (too hot). Spent the day stripping paint and cleaning and degreasing parts and priming and painting and detailing. I will post up the stamping when I can get a clear look at the block. It is difficult to read the stamping with the headers.
