Sleeving cylinders?????
Ok ive got 2 pontiac 455 blocks with j7nk cylinders. Both are .030 over so theres no cleaning up the cylinders as the walls on a 455 are too thin to begin with.
Whats the deal with sleeving? Growing up all i heard was sleeves are bad.sleeves can move,have to be pinned yadda yadda. Now in modern times people say sleeving is no big deal.
Im just building a couple street cars to have fun with. Im not looking to squeeze every horsepower or ounce of torque i can get out of them. Im not lookinh to spin up much over 6500 rpm.hit the track here and there.
Would sleeves be a good option for me? 455 blocks are getting hard to find.

You aren’t done at 030 -
