Well I've never heard of all poly mounts causing anything like that, although I've never tried it either. I run front and mid-motor plates with a poly trans mount and have never had a problem with that. I don't know what would have caused it but, I would think that case is garbage now
It broke behind the front pump, even the sealing surface for the pumps O-ring is gone! An Ultra bell bolts to the front of the front pump.

WOW, I sure am glad I saw this post! I have never used poly mounts either, was going to put them on my latest "affair" (as my wife calls them). Thinking I may pass on that idea now!!
Good luck figuring it out.

If you did it in the burnout, then I would think it has to be in the Driveshaft...Maybe a U-Joint Failed maybe the driveshaft was bent?
There wasn't alot of load on it during a burnout. So I am guessing you had the 7/8-1" of play for the driveshaft also. I had a U-Joint Break the Rear one twice..about the finishline and it did the same thing. I would put my money on a U-Joint Failure. I don't think the mounts had anything to do with it. I run stock rubber shells on the frame and a replacement rubber trans mount. No issue's.
