w/ less than 20k on it ... machine shop completely disassembled and reassembled ..I don't see how a newer motor could be my problem and not the machinist ?? ..my motor didn't knock previously ... only had a broken ring landings / lancing or whatever ...anyways ..u asked a question about machine shops ... I gave u my opinoin based on experience ... if your suggestion is to call g.dupree or jwt ..why don't u do that for your motor project ?? I have made up my mind about what I should do to get my car running as quickly as possible...
