The bore was worn slap out and the tractor chased away every mosquito in the county. I'm not sure how long it ran that way. I tried to get it bored out, but the block was cracked. I ended up with an other block. I agree with old, I would not try the oversized piston route. The re-sleeve and new piston route will give you a like new tractor that can be rebuilt again.

If you have to bore to install the thick wall sleeves, why do you have to throw away block after running pistons in block? I do not like dry wall sleeves as they do not conduct the heat away from piston/rings. Look at the outside of a used dry wall sleeve. They are usually blue from heat. Same heat gets to piston/rings.

If the block was originaly bored for the thin sleeves it wouldn't hurt it to run pistons in the parent bore. If you ever need to rebuild it again - which nowadays is unlikely - then bore it for the thicker sleeves. I probably wouldn't do it if it had the thicker sleeves already though. [Reply]  [No Email]

No sleeves no way to bring it back to what it was new. Been building engines since the 60s and yep do some high pro. stuff like the 292-6 Chev here in the office that has been bored 60 over crank turned and has a high pro cam in it. But it will and can never be put back to what it was when new [Reply]  [No Email]
