How much can a stock Turbo 400 handle?
About 400-450 HP/TQ is the limit on the stock TH400. With ONE almost free modification and some minor valve body calibration changes, 800 HP on an otherwise stock TH400 is not a problem if it’s assembled well (good endplay, etc), and the 34 element sprag is a wise addition above 450 HP or any drag usage.
