If you remember the 408 put out 552hp and 530 lb-ft-tq on the engine dyno at Westech.
I wanted to back up that number so with the engine installed we strapped her down to thier Superflow chassis dyno.
After a little bit of tuning (a bit rich at cruise, went from 73/73 jets to 76/70) we had a good repeatable number.
448.3 rear-wheel HP and 405.4 rear wheel torque!! :woot:
I'm very happy with this.. considering the 9" rear that's a very respectable drivetrain loss and I should be able to knock down some good times. Also, the Ford pulls like a freight train. In fact the street tires just go up in smoke.
I think I have a shot at taking down the big-block Chevelle :D
