What does it take to...
-The Project: 4l60e to th400 swap
.............
Im in the middle of a turbo lt1 build and am looking to run circa 8psi for now on a stock motor. This is a track car and i can afford to blow the engine sky high so, it will stay stock for now.(if the engine blows, i just build it bigger and better) Ive read a bit about people putting boost to their stock transmissions and the outcome has always been the same... A blown, no good tranny. I can not justify blowing a perfectly good stocker trans. So my solution is to replace the stock trans with a th400 being donated by a buddy of mine. For you more experienced guys.. what all does this involve and what stall should i be running?
