How to Make a Mustang GT Really Run

A supercharger is a great way to add serious horsepower to a 2018-2021 Ford Mustang GT. Take Edelbrock’s E-Force Stage 2 Supercharger System. It features a high-efficiency Eaton TVS R2650 rotor assembly with larger bearings and more robust timing gears to deliver an ultra-smooth and linear torque curve at all points in the power band. The high-capacity, dual-pass, air-to-water intercooler keeps inlet temperatures under control, and the kit has everything needed for a complete, bolt-on installation.

Add Better Valve Springs When You Swap Cams in Your LS Engine

If you’re thinking about installing a hotter cam in your LS engine, it’s worth installing a better set of valve springs like COMP Cams Beehive LS6+ Valve Springs. The springs can handle up to .030-inch of valve lift compared to the  GM “blue” LS6 factory springs. They also have 4% higher seat and open loads for better dynamic control of the valvetrain. You even have a choice of steel or titanium retainers.

Back Your Small Block Ford with a GM Four-Speed Automatic?

Sounds like blasphemy, but running a GM 700R4 or 4L80E four-speed automatic behind a small block Ford is pretty popular. And one of the best ways to do that is by using a TCI 4x Four-Speed 700R4 or 4L80E Transmission Package. The kits have an exact-fit bellhousing, an adapter flexplate, pilot adapter, dipstick and other accessories to make the swap a bolt-on—just use the lockup converter of your choice. The 4x Four-Speed 700R4 is available to handle 550 or 750 horsepower. The 4X Four-Speed 4L80E is rated to handle 875 horsepower.
