Most all of the TH400's I have had or seen are short shaft slip yoke (car tranys) 60's and 70's models
Actually the two I have are from 74 and 75 GM trucks that had big blocks in front of them.
The first TH400 or should I say 475 I built to sit behind a stout 454 in a 71 elcamino, still runs today was a short shaft. I think that 475 was from a bread truck. Had straight cut gears. Love to hear that trany whine. I think Impalas had the long shaft's 400's

Yep, the straight cut gears are noisy as hell, but strong as hell. If you ever want to find one of those, check motorhomes and old ass school buses that used the 400 before they got smart and used Allisons. Allisons are actually very similar to the 475.
