Maybe time for an Ultrabell bellhousing..... as far as removing the old stock bellhousing, most of the work has already been done.

I was there watching. Bad wheel hop can cause that along with solid motor mounts and solid trans mount being run together. Not a good idea to run there until fresh rubber gets laid down unless you can keep wheel hop at a minimum. Track is very slick right now. I cracked a turbo 350 across the middle of the trans there years ago. My cheaters balled up so bad the rim hit the ground and unloaded and did it again. If I put it in reverse it would open the crack and fluid would go all over the place. In forward gears it was fine
We left right after the rain. They were having so many issues with the timing system it got frustrating to try and watch. Whatcha doing with that big huge converter? Looks like a 10" converter.

I've run all solid mounts for 10 years--no broken trans ever. If the engine, trans, and chassis are all tied together solidly, what's going to cause the trans to break? It breaks from twisting-something is flexing where it shouldn't be. Does the car have frame connectors? Are the body mounts soft and squishy? Is the rollbar built properly? Does it tie into the subframe connectors?
It looks like it would be easy to add an Ultrabell now! I went to one a couple years ago after a friend was helping me remove the trans and left a bolt in--lifting it with the floor jack...snap! That's why I prefer to work alone.

Broke first pass! This is what the slip shows. I shut it down, or should i say IT shut me down......
1.6 60 ft
4.929 330 ft
7.97 660 ft @ 67.47 MPH
The other lane was;
2.439 60 ft
5.09 330ft
7.16 660ft @ 119.36
They were having issues with the system... I dont know how accurate that slip is....

That's not going to break a case either. What do you consider incorrect pinion angle? I ran 8 degrees for many years--it doesn't do anything. Have you ever looked at the angle on some of the trucks these morons drive--4 ft. of clearance and the driveshaft pointing straight down then practically a right angle into the diff?
A driveshaft coming apart is a more likely suspect-when a U-joint goes away the shaft can move enough to beat the trans to death.

sometimes ,,
some people might have some luck using both solid mounts on engine and tranny , i've always myself used a rubber tranny mount with solid engine. Prolly the only thing i've never broke is a trans case. Everything is subject to failure though. Sometimes things just break.

Man I am sorry to hear about you misfortune. Have you ever thought about going to a ATI or D/B case? I know as soon as I get my engine done I am going to be changing out my STOCK PG case to one of theses.
PS
I run solid motor mount's.....Mid's......... and tranny and never had any problem's

I also run the solid motor mounts with rubber tranny mount and have not had any trouble to date....knock on wood.
I agree that as is the case with most things it is a weak link that is found with upgrades or the parts time is up. Nothing is eternal, not even aftermarket stuff.
I know that if that happens to me I will be going to an aftermarket case just to be safe, although all my friends will be telling me to go to a glide.

I tried a urethane trans mount once--tore it in half. All solids for 10 years, works just fine.

ya gotta wonder ,,
ya gotta really think what might have caused this. Some force was acting on this that was not inline with the rotational mass of the internals of the transmission possibly. I used to work around jet engines in the Navy and they are very sensitive to stuff like that. Vibration is a killer to them , and may have been the culprit here.
Was your engine balanced ??
I knew a big block racer back in the 70's that ran a 454 with a turbo 350 and never had a case problem. He was one of those guys that ran one track on sat and a different one on sunday all season long too

x2 on what he said. Don't just assume it was more power that caused that to break. TH350 cases are fine with more power than you have. Something else caused that baby to break. Some sort of flex/bind/vibration.

Seeing how "all over the place" this dude is, I'm surprised he doesn't have one
Sorry guy...But the tunnel ram with the blower scoop makes for endless jokes coming from me:beat::no:
