Oh and my buddy had to swap block's on his 460 stroker because of a bad casting, he had the shop prep the the new block and assemble the short block. When we got it home and on the stand we took off the plastic bag and found crud stuck to the plastic from the top side of the motor. They never cleaned the lifter galley on the new/used block, i told him to take it back but he cleaned it up and put it together. It's putting down 948hp to the rear wheel's and was a very expensive build, no way i would have taken the chance but he got lucky so far...
