ill need to take some pics or figure out what I have, but I purchased a "t2" engine from a guy in the auto trader (ya, a long time ago) that said it was a common block. when I picked it up, it had the t2 1 piece intake and all the accessories so I was happy. once I got it home to tear it down, and pulled off the timing cover I realized it had a square tooth timing belt? I think the block was cast as a 1990? no idea if it has old accessories or common block accessories, but strange none the less...
