Have sleeved all 8 more than once. It only pays if you are a machinist--As others have said--one hole will run about 150-200 bucks. Done properly you cannot tell. J.Rob
Machinist or not, It pays if you have a high dollar car with matching numbers motor like post # 21.....Even if it cost 800-1200 for 8 sleeves, a matching numbers 427 vette versus a non-matching numbers motor is probably about 5-10K difference.... It would be just like one of us Mopar fanatics sleeving a matching number 426 Hemi or 440 motor car.....The value is a lot more than 1200.00....
