Where did you get the sleeves? Where did you get the work done?You can take your cylinders and have a sleeve installed on them and then bore the cylinder to your desired size. I did this and bored my engine .250 over. That made mine 140cid. J&E made me a set of Pistons as well. The only thing is, Piston company's only make a set of 4 so you have to buy 4.
