Everyone i have talked to has had no problems with there TH400's, my dad had a stock one with a shift kit behind his 427 for years.

honestly, i heard the exact same thing about TH350's, not trying to argue either, just saying, GM put the th400 behind the 510 Ft/Lbs 1970 Buick 455, i think it will be fine for my 350?

id honestly go with a 4l80e if i was u

I'd do a th350, but already having a th400, no way would I NOT use it. If you were buying or finding one I'd g for a 350 though. As for the DS I'll see if I can find the charts I saved for lengths, driveshaft, you can change the yoke to match the spline. I'm pretty sure 700r4, th350, and maybe the 60's and 60e's are 27/26 spline and then the 400 is a 32 spline.

here's one table of measures I found..

Transmission Length
Case to ext. housing Overall length Bellhousing to mount
Powerglide (short tail) 15 ¼ 24 ¼ 19 ½
Powerglide (long tail) 15 ¼ 27 ½ 20 ½
THM 200, 200C (the 3 speed) 27 5/8 27 5/8 20 1/8
THM 250 21 5/8 27 5/8 20 3/8
THM 350, 350C (short tail) 21 5/8 27 5/8 20 3/8
THM 350, 350C (long tail) 21 5/8 30 5/8 20 3/8
THM 400 (short tail) 24 3/8 28 ¼ 26 ¾
THM 400 (long tail) 24 3/8 34 28
200R4 27 ¾ 27 ¾ 26 7/8
700R4, 4L60, 4L60E 23 3/8 30 ¾ 22 3/8
4L80-E ? 31.5 30.38
