Anybody got transmission case length info??

I'm looking for the case length specs for the TH200, TH350, and TH400 ... if anyone has these specs or a website that has these specs listed I would greatly appreciate it. Thanks in advance.

Transmission: Powerglide
Axle/Gears: Ford 9"/31 spline spool/4.86
Total length (bellhousing to rear seal)

TH200 = 27 5/8"
TH350 (short tail shaft) = 27 5/8"
TH350 (long tail shaft) = 30 5/8"
TH400 (short tail shaft) = 28 1/4"
TH400 (long tail shaft) = 34"
700R4 = 30 3/4"
200-4R = 27 3/4"
4L80E = 31 1/2"
TH250 = 27 5/8"
PG (short tail shaft) = 24 1/4"
PG (long tail shaft) = 27 1/2"

Mounting length (bellhousing to tranny mount)

TH200 = 20 1/8"
TH350 = 20 3/8"
TH400 (short tail shaft) = 26 3/4"
TH400 (long tail shaft) = 28"
700R4 = 22 3/8"
200-4R = 26 7/8"
4L80E = 30 3/8"
TH250 = 20 3/8"
PG (short tail shaft) = 19 1/2"
PG (long tail shaft) = 20 1/2"

Good enough?

These sound better. Stephen, are you sure your records are right? You show the 700R4 only being 1/8" longer than the TH350 short tail and I'm pretty sure it's more like 2 3/4" like Jay shows because when I replaced my 700R4 with the TH350, the adapter block (so you can use the same driveshaft) was more than 2" long.

The main reasoning behind my questions about case lengths is because the S-10 I'm getting originally had the TH200 and I know the TH350 can be bolted directly in place using the same driveshaft and everything but I'm wanting to put a TH400 in there instead and was wondering if there would be too much difference between the TH350 and the TH400 to be able to use the same driveshaft. The crossmember location is not a big deal to relocate so I'm not too worried about that part.

(Just as a kind correction... it's a 200-4R, not a 200R4. I've seen lots of people call it a 200R4.)

Oops. I had an error. The correction has been done. Those measurements are from an article on tranny swaps. December 1993 Chevy High Performance.

It was too early in the morning to type all those numbers.
