I had this blower setup in me 03 silverado. The power curve was great. Even for a truck. 12.78@109mph ,2.03 60ft.street tire/ 12.48@112mph,2.07 60ft. street tires,shot of nitris.
first time commenting. I have a 74 260 with an LQ4/magnacharger going in. It's working, but a tight fit. Mine has the truck excessories that stick out further. Good luck with projects
