So I may have the opportunity to pick up a 5.7 3G hemi at the right price, but there is a problem with it. I haven't called to get more information yet, but from the ad it sounds like it may have snapped a rod or something. However, it sounds like it didn't punch through the block since the seller said that it only needed a sleeve and that he had a rod, piston, and sleeve ready to go that he would sell with the setup. My question is how bad is it to sleeve a cylinder? I'm not looking to go real crazy with my build, but I'm probably going to be in the neighborhood of 400 hp now and maybe around 500 later. Should I just pass on this and keep looking or would this be a good chance to get a hemi for my project at the right price?
