My buddy has gone thru more than a couple of them buggers on his th350, he got the best of everything in that department and it still tears up.
I'd get a th400 or better yet, a powerglide.

use all th400 parts and save the money you would be wasting
The trick is to start with a turbo 400 case, then assemble it with the parts that fit in the case. This is the most durable 3 speed trans that GM makes.
A 350 is best left to the hot rod / car show / show car wana bees
However, for thousands of dollars, there are several trans shops that will make a 350 as strong as a stock $200 dollar 400.

ive been running the one in my Monte for 11 years now with a 4000 stall running 7.70 in the 1/8th and for the last year with a 100 shot of nitrous and its still together and its basically all stock inside . I like the tranny , its light and I like the gearing. Its time for a rebuild and if it held up at the dragstrip for this long im sure if I upgrade to some better parts Ill still get use out of it for a long time. Thanks for the recomendation on the sprag.

Purple...sometimes things unexplainable just happen. You have had some incredible luck with what you have. I would be almost afraid to touch that thing. You know how it works with performance parts, just when it is supposed to make something better......well, I think we all have been there and done that.
