Heh, heh, gas mileage really isn't my thing. Power increase is usually a good 20hp to the wheels, give or take. Mine went on the same time as the 6.0l went in, so I really can't give an exact difference.

And the thorleys will work for a Z71, as will the Arizona Speed and Marine, the other guys headers, and Dynatechs. Best bang for the buck would be the Thorleys.
