1955 Chevy 265 block. Part # 3703524. This is basically a short block with the pistons, crank, etc. The block is very greasy. The cylinder bores have surface rust. I didn't pull the pan so I don't know the condition of the crank, rods, etc. The motor will need a complete rebuild. I have the original heads for sale on another ad on CL. Asking $75. but will listen to all offers.
