4l60 or th400? hey everyone i gotta project that im about to start. its a 1981 z28 that i plan on putting an ls1 or ls1 swap with a twin turbo setup. my question is, is that can you bolt up a th400 trans up to the ls1 or ls2 or do you need a 4160?

A TH400 would be a good choice for that setup as the torque produced by the TT LSx engine will be more than you would want to put through the 4L60 (700R4) for much time at all. It could easily be a high maintenance situation with the 4L60.
The 400 could take that punishment easily if it is well built. But on the other hand, if you were wanting to preserve driveability in the interest of building a street beast the 4L80E would be just the unit. It is based on the TH400 and is an Overdrive unit. It would need it's own stand alone controller, can be outfitted with a trans brake for spooling at the line and would give you the performance you are looking for I believe.
If you would like to learn more about any of those trannies just pick up the phone and give us a call... we could help you understand the pros and cons of each unit! We help customers plan their hot rod builds every day.
Hope that helps!
