    When I disassembled the engine I found water under cylinder #3 only. I'm thinking water entered throught the hole in the case after it threw a rod.

    it didn't just trough a rod like that, it had to give you plenty of warning, you probably ran it a few miles before it stopped, to much damage to tell, bearing failure lack of oil

    if its a known project then just do your thing..

    replace block, replace crank, pistons for good measure...hook up with one of the tuners on here and have em either convert you to a BB engine or atleast do some porting/polishing. Personally I've gone with Lowell Horning twice now and I absolutely love his work...Waterwoody (kevin) had shadowed and trained with Lowell for a while so I'd reach out to him as well.

    wow - that looks familiar! I also blew a hole in my crank case in the exact same spot... Chewed up piston #2 and broke the claws off cylinder #3 on my 2000 XLL1200. I pulled the motor right away so I dont have the corrosion, but everything else looks pretty similar.
