Anyone with experience with rebuilding an older 6 cylinder 250 (GM lol) engine. The unit had been torn down to rebuild but due to unfortunate circumstances never reassembled. It was stored in an old school bus for a few years and the crank is somewhat rusted. Underneath the rust the journals seem in decent shape. Would a polishing make the shaft useable again or is a regrind mandatory? I used a scouring pad and it brings back some shine but there is still evidence of rust pits. The cylinder walls also have rust. Taper us about .006. Pass with a new set of rings or rebore required??
The price for the gaskets, shells, rings tossed in makes this attractive at $300. Worth a try? How much can a person expect to see out of this thing?
