I have a 71 ramair block with crank,rods,& pistons bored .030 over with casting 481988 I also have the original ramair heads that were on it casting 96.the heads have roller rockers and have been milled .010 for flatness. This motor was originally rebuilt 20 yrs ago and wrapped in plastic without oil pan,valley pan,& valve covers.It was stored in a barn the whole time but lost the plastic some years ago.the block has surface rust and must be disassembled & cleaned.cylinders have very little surface rust and probly just need to be honed. The heads were removed about a month ago and somehow didnt rust like the outside of the block.missing oilpan,valleypan,valvecovers,distributor,timing cover,&oil pump.Have holley street dominator intake,starter,flywheel,clutch,pressureplate.
