TH350 behind a Big Block

[Rank]

... seems to me that would be the weak link in the power train. Why not stick with the tried and true TH400??

I plan on running a 454 and automatic. I have a couple of TH350s on hand and one questionable TH400 out of a truck which I would hate to install and then pull due to the situation that it might be worn out. Is the TH350 a tested replacement?

Any advantages to running the TH350?? All I can think of is negatives.

....... be my guinea pig! LOL
