        mustang cams in a sport trac

        i order the comp cams stage 1 for a 2008 mustang BUT i used for my 2007 ford sport trac 4.6L 3valve like many other parts that i ordered from American Muscle, before i installed the cams i dyno the truck and did 258hp and 265tq after i install the cams i drove the truck to the dyno ( yes you can drive the car after you install the cams, is safe ) and did 286hp and 295tq, i gain 28hp and 30tq, yes, recommend these cams, these are not the only parts that you can use from a mustang to your sport trac 4,6l there are many interchangeable parts that you can use for your 4.6 sport trac.

        Nice Gains

        Really good gains with no real low end loss. car pulls much harder after 4500 rpm. tune from bama was great, took a little tweaks but in the end really happy with the purchase and shipping was fast, about a 4 hour job to do

      With these cams, will I have to get a tune

      • Hello! With the Comp Cams Stage I XFI NSR Camshafts you do not need a tune.

      What are the difference of the stage 1 and stage 2 NSR?

      • The higher the stage the better the gains you will receive from the camshafts.

      do I need a new tune

      • If I were adding these cams to a stock engine, I would definitely take it to a reputable Dyno shop.

      Are these safe for daily driving? How do they drive in low rpm? Would you recommend for daily driving?

      • Theses are Mild Cams and would be fine for a daily driver. In a Automatic Transmission you might not even notice them in city driving. With a standard you will notice them a little more. Looking at the lift and duration you will see and power gain at about 1200-1500RPM but the real power will be up around 4 to 5000. A Cold Air Intake and a throttle body upgrade would go a long way complimenting them.

      Will these pass CA smog?? Retune?

      • No these are not CARB certified. A tune will be required however.
