Default 408 dyno #'s after T/B change!
I changed the 90deg elbow/ 90mm throttle body to a 4500 Fast throttle body and went to dyno to see the difference. Before it made 512hp through th400 and drag radials. This time it made 562hp through the same th400 and on slicks. It picked up a little on spray also. Not to bad for a 4 year old motor.

From what I can tell the TQ curve might have moved down a little and picked up almost 30ft/lbs.
