    that's not a good idea as the sleeves are a combination of steel inner liner and aluminum outer.If you bore it out that far you will have very thin steel liners= KABOOM. look into sleeving it if you want to bore that large. largest i've seen to bore stock sleeve is 81.5MM

    hmm......personally I would upgrade, I mean the eagle rods cost like 400 bucks, if not then shotpeen the ls rods.

    I have read mixed emotions about using the ls rods in high rpms, in other words there are people out there running ls rods to high rpms and having them last.
