I have a 291 casting 4.1 block that I would like to sell. I just picked up the block from the machine shop where it was cleaned, checked out, and magged and it got a clean bill of health. The block is .030 over now and will require another .010 to clean up so it will end up .040 over. I want $285 for the block or I would trade it towards an aftermarket downpipe or a turbo in the 63ish range or maybe a B2B FAST. Thanks
