    Re: How to install 87 forged 2.2 crank in 90 common block?

    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...

    I have an 89 TII short block and a 93 2.5T short block

    The casting quality of the 93 block is far superior to the 89

    Casting is cleaned and has no little barbs of metal sticking up from it
    also the reinforcement bar cast along the frost plug holes at the back of the block is flat and has a uniform thickness as it runs from one end to the other
    The 89 , that same reinforcement is not uniform in thickness - in fact it's very far from being flat as it runs across the back of the block

    By thickness I mean to say if reference to the amount the reinforcement is raised from the rest of the back of the block , not the width of the reinforcement

    Any appreciable weight differences between the two?

    EDIT: NM you said short block, I thought you had bare blocks to compare

    It is a good question as the main webs in the 92-3 blocks are supposedly thicker but I still have yet to confirm that

    Both still need torn down as the steel 89. Crank is going in the 93 2.5 block
