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.

I wonder why people would ask "why the gt40 alum.heads"? Because it hurts that 408. Whenever proper heads are put on that engine I'm sure it'll gain 50-100 horsepower.
