Turbo 400, eh? Is that a common pairing with the DOHC?


I've had a couple 68 Firebirds that had the Turbo 400 and they were great transmissions. I went through a couple engines but never had an ounce of trouble with the trannys.

Coyote pshhhhhhht. Ill be running 35 psi on e85 with a NA 4.6 that makes more power than a coyote NA for NA. Yes most high power builds run the th400.
