Good advice, except his engine is bored 80, not 60. The same logic applies, as the cost of a set of pistons can be deducted from the sleeve cost if they can be re-used. Sleeving only 3 holes and recycling the pistons would be the least expensive way to go in this case. One thing I don't have to consider is machining cost, since I have my own boring bar(s) and cylinder hones, so the only cost involved is buying the sleeves. I realize that's not the case for everyone!
