    in my opinion its not even worth thinking about doing since you could spend the same money on an xcr or ultra motor with MUc better results. the XLT cranks also have a horrible reputation for a reason.

    Think PSI started building those motors before the XCR600, Ultra and XCR 800 came out (1996)

    I really can't understand why anyone would bother going to all this work and expense on one of these monoblock engines when you could achieve similar results with the 600-680 xcr/ultra engine. Not to mention the xcr 800 engine. Go figure.

    ?PSI XLT cylinder-reed block

    Okay, I saw this on E-bay and my curiosity got the best of me... Thought this might be an interesting (I know, expensive) hop-up for my XLT. Looking to get more information on these cylinders on who made them and what the hot setups back in the day were for them.  I have learned so far that this will be very expensive to build, that custom heads and machine work to XLT bottom end to make the crank survive along with the resleeving/porting work will be needed.  The only money I have in this so far is the block itself.  Just wanting to get more info before I decide to pull the trigger and wade into this project.

    It's a bare casting that needs cleaned up, ported, and sleeved. Current bore is 63mm (2.480"). The guy I got this from had custom sleeves/pistons and a stroker crank to get 990cc's. He made his own heads and reed adapters. I don't plan on going that wild, this will be something I will work at as I have the funds to get things done. I was just curious if anyone had any experience with these in the XLT form (I know there are some cylinder-reed PSI setups out there based off a 650 triple bottom end) with some suggestions and things to look out for. Thanks!
