i know a diesel mech. that had a really bad cylinder so he bored the cylinder enough so that a sleeve would fit in snug. then he bored the sleeve to the stock std. size for a new std. piston would fit in it. believe it or not, it ran top notch and is still going. i was wondering, since i have a .060 block and if i ever need to redo the motor again, can i just resleeve it. i was looking in MM&FF and i saw something about engine sleeves and it gave me the idea. would this make my engine run cooler again. if i do this i would get forged slugs and throw a turbo and nos on it with ARP rod bolts and a main cap girdle. i would also have ARP head studs and adj. roller rockers. with hopefully a good set of aluminum heads.
