the gears, clutches, sprags, eveything is biger. They came behind 450hp big blocks, in moter omes, dump trucks, you name it. With aftermarket parts they will suport what ever kind of hp you make. The down fall of the TH 400 is the 1st gear ratio is 2.48 to 1, the 700 r4 is 3.06 to 1. tis is like going from a 3.08 rear end to 3.73s off the line.

Yep....and the other drawback is the 400 takes a bunch more hp outta the mix than a 350.
