Finally getting my car tuned! Click here for the Dyno graph. http://i44.photobucket.com/albums/f21/MPsoldier187/Dyno%20graph/Dyno.jpg 321hp and 337trq to the tires on the lean tune, that was deemed unsafe. made 314hp and 329trq to the tires on the "safe" tune. This was about the 10th pull during the tuning to get these numbers, so the car was VERY hot, also 92degrees out. So with the car cool, and it cooler outside, the car would hit at least 320-330hp.

1989 Mustang LX Dyno Test
A lot of people watching this video are going to ask, "Why would you put GT40 heads on a 408!?" It's only temporary. More power is just not a priority right now. There are other issues to sort out first with the suspension and brakes. I already had these heads on my 302 combo and had to reuse them to get the car on the street again. One has to love that the the torque curve remains above 370 from 3500 to 5200 RPM! This is a fairly low quality video. I may redo it later in HQ.
