I have a 291 casting 4.1 block that I would like to sell. I took the block to a machine shop and had it tanked and magged and and the machine shop gave it a clean bill of health. The block is .030 over now and the machine shop said that it will clean up nicely at .040 over. I will also include a 14 bolt oil pan and pick up tube. I want $175 plus shipping for the block or I would trade for a regular translator/MAF set up or I would trade towards a turbo in the 61-64mm range or a SLIC intercooler.
