Default e.t. improvements

Im tired of going through clutches in my car so im going with a th400. I just wanted to know how much E.t. if any you guys picked up over the 6speed. Also ive heard that a th400 takes more power to run than a th350 is this true?

Can't help you here since I've always had the 4L60E auto.

This is true. Weighs more too I believe. But the TH400 can be built to hold more power then the TH350. Many consider a well built TH400 to be bullet proof. So if you're going to make a ton of power now or in the future (700+ to the wheels) then I'd just go TH400 with RMVB and a T-brake and call it a day.

But for more modest power goals a well built TH350 could get the job done a little more efficiently.

I think if you went with somebody who knows how to build a transmission, I do believe a TH350 will be fine.

I was not one that made the switch, but, taking out driver factors, you could probably see a couple tenths quicker. you'll lose mph with the auto though. your 60 ft is where you'll pick up the most time.
