nope for a 440 you need a new sleeve. 60 over is a 416 80 over is a 426.

so it would still be 400 then. i was just wondering cuz my bike was burnin oil bad and i brought it to get worked on and had to have it bored .50 over or whatever, with a new piston kit and gasket set. and i could notice a difference in the bike, i guess it's just runnin really good right now.

Correct me if I'm worng but I don't think .50 is a bore size. I thought they go .20 .40 .60 .80?
