Guys, I have 80mm pistons, rings & pins. These are brand new in the box. I would like to use these. All I need is jugs or sleeve my old jugs. I seen Heiden tuning sells 80mm jugs for $400 euros. With the exchange rate and shipping, I was wondering if I could do better? Time I buy sleeves and have my old jugs machined....just wondering what's the best, most frugal route to take. Today's best option. I know, I know, "search forums". I did but it was a long winding road that was dated. Most a better part of a decade ago. Any input would be appreciated. I have a 81' 447 motor to rebuild this round.
