With the FRPP Hot Rod Cams in & out of backorder status, we knew another option needed to be provided. We are happy to offer the Comp Cams Mutha Thumpr Cam Kit with Custom Blow-By Racing tune for your 2005-10 Ford Mustang GT 4.6L 3V! These cams are a great way to increase the horsepower and torque in your Mustang & they have a mean sounding idle. These cams require Phaser Limiters & a Custom Tune, which we've included for you in this kit. The Comp 127020 Mutha Thumpr cams are compatible with your stock heads & valve springs.

We have teamed up with Blow-By Racing to get you the tune you need for your Mustang to get you back on the road fast and save you $$$$$! We incorporate the modifications you already have and develop a custom tune specifically for your Mustang based on the information you give us. Check out the details below!
