donno havn't taked it apart yet. no piston through the block or anything like that though. It threw it after it was knocking and I was just trying to move the truck and was keeping the revs low. I'll probably reuse the engine block itself, but I'm sure I'll need to replace a bunch of the internals...

I Think for now I'll just install a normal 22r block while I rebuild/build up this one so I can drive it. I have to many non working cars... So anyone have a good 22r block to sell me?
