    Think of all the hassles you would have saved with a J&W replacement bellhousing.

    That may have been helpful if you posted it in your first reply. I never knew such an item existed.

    Yes. maybe you're right, the case was just done. We cracked a few Th350 units but that was more due to the car twisting on launch than anything else. Once we got the chassis squared away, it stopped breaking cases.
    Remember the "13"

    A lot of race cars run a mid-plate between the engine and bell housing. I have that setup on my Camaro that really feels like it ties the drivetrain, and car together. The engine is bolted solidly front, and rear in the chassis with the trans attached to it with a poly rear mount.

    Solid rear mounts will tear up a transmission case.

    Beyond that, most case failures are user induced. Running with loose bolts, tightening the bellhousing to engine bolts when the assembly is in some kind of bind, etc. This one doesn't look quite so obviously that because the crack didn't start or go through a bolt hole. Without an obvious clue, just chalk it up to bad luck, the previous owner, jack rabbit starts, and just hot rodding. It probably won't happen again, at least the same way if you pay attention to the installation.

    With the loose converter I doubt I'll have a problem again. It doesn't bang gears like it did, it was shifting really, really hard before and yes I beat the crap out of it.

    Just how does a loose converter help? It's the opposite.

    It doesn't have the hard banging into gear when shifting anymore.

    There was a pic in the first post. Oh well, besides not being an 8 bolt pump case, it was just shot besides the crack. Three or so stripped holes half ass patched up, one of them being a pump bolt which the new housing bolts to.
