Going to be rebuilding a 310 or 330(not sure what they called them back in '88). The motor runs fine, only 220 hours, but we need to pull it to replace the oil pan, so we are going to build it up a bit. I have never built a big block, only small blocks, and outboards so we are going to get someone to do the assembly(probably MESA since they are local). Looking for Cam, intake, pison, head suggestions. We are going to reuse the bottom end, even if it is cast, since this will be kept somewhat mild, and it is in good shape. Also going to replaqce the exhaust while its out. Does anyone have suggestions, or some used parts for sale?? What kind of power could I get while keeping is reliable???
