That looks exactly like my 400! I spit my driveshaft out at the finish line , it had a slight vibration for .5 seconds bere leaving!. However I think the trans may have been cracked before. I had a leak and I could never find it , the general area was where the cooling lines go in. I also cracked a Th350 before I switched to a 400. I too run poly engine and trans mounts and I'd say my body mounts are in poor condition. 70 Monte , 3850lbs w driver , 530 hp 383 , 4000 flash. If it makes you feel better I'm on my third trans. TH350 broke case , TH350 broke sprag , TH400 broke case.

This definantly a drive shaft. Check for end play in shaft should have at least 3/4" of movement. I speak from my own experiance. it took me three transmission in less than 100' of use to figure out. When checking
Driveshaft make sure weight of car is on axles. If you have real soft springs remove the rear springs and check.

it aint the poly mounts, they do have movement, so you aint rigid there. if you have 12 pt. cage ,you have frame connecters, so you are solid there. body could fly off and i dont think it would cause that. i think it would have to have had a violent reaction to end up there.pinion angle , drive shaft or u joints are about all i can come up with. i could have been stressed when it was in the other car and broke on lucky you.good luck hope you find it fast before the cha-ching machine gets turned on high.

Lively you just gave me an idea.
I have about 600 lbs worth of Olympic free weights( you know barbell and plates) I could pile them in the trunk for a pass just so I could get a picture like his...lol :P
My car 60 fts about the same as his (1.32) but it sure don't do that.
Don't really think I want it to either...I tear up enough parts as it is. :lol:

We had a tranny rebuilt about ten years ago and they didn't put the bushing in the front pump for use with a turbo spline input shaft. It lasted
3/4 of a run.
Also we used to run a mounts like what you are using, now we just run stock mounts with longer bolts in them so they bottom out and get about a 1/4" travel. Even though it should never move and if it would come apart the bolts keep the case from coming out.
5.60's 1/8 in a 4 link car and haven't broke a tranny case in a very long time.
