yeah old turbo350s hold up pretty good even when stock. my buddy had an 86 silverado with a 454 that had all the goodies, such as a racing cam, installed. he could be cruising along at 30 mph and just stomp it and loosen up the rear tires. he used a stock th350 in that sucker and it never gave him any trouble.

as for the th400... i had one in my truck before i dismantled it for restoration and it seemed to work very well. one time this stupid chick i was hanging out with (a blonde by the way lol) decided to throw the floorshifter up into reverse randomly to see what would happen. mind you i was going about 35 or 40 in the forward direction when she did this, and the tranny actually did shift into reverse and started spinning my rear tires backwards and everything, at least until i let off the gas a moment later and it killed the motor lol. didnt seem to really mess it up at all though and i was really surprised.
