how much hp, can th350 handle?

im having a 396 bb built up for my 72 shortbox, i want to install a th400 but not looking forward to getting a different yoke and gettting the shaft cut..... should i just stay with a th350? or is it worth the work to a th400? thanks!

are you rebuilding the TH350? It's doubtful any of the one's mentioned are anywhere near stock. They can undoubtably be built ($$) to withstand alot of punishment. It also depends on how bad your going to treat it(just street tires or track/slicks...). For peace of mind I went ahead and swapped in a TH400, because I didn't want to be swapping transmissions frequently. Most likely, if you're talking about a cruiser/ street tire smoker, the 350 will be fine.
