    i have , but i swapped in a 455, it wasn't that hard to do. as for power it depends if its built or stock
    if its stock and you know the year you can look up specs in an old motors manual.

    I've got a TH400 BOP tranny in the garage! Interested? Other than that, I don't expect that it should be a difficult install.... /forums/images/icons/wink.gif

    Below the right side head (passenger side), you should see a stamped two digit letter code on the flat portion of the block. This will have the "Engine Code". Have him get me the engine code and I will tell you what the factory specs are. Also, give me the head code on the center two exhaust ports.

    Pontiacs make loads of torque!

    If he wants a BOP TH400 I have a friend in Central Oregon with an extra one... Swap out the output shaft for the 4x4 version and it should bolt up to the T-case.
