Ed spent hours upon hours polishing everything you see because an 8- or 9-second timeslip shouldn't mean an unsightly engine bay. Underneath the sea of braided lines is a set of polished valve covers fabricated by Keith Mease. The master fabricator also welded and bent up the turbo manifolds and 3.5-inch downpipes in addition to the sheet metal intake manifold, intake tubing and intercooler. In combination with a pair of T66s, which are good for up to 1,400 hp, the race ported Brodix heads, Bowtie block, solid roller, and heavy-duty valvetrain should be able to create enough power to carry the 3,600-pound truck into the 8s with ease.

One of the most unique features of this truck is the custom intake trumpets for the turbos, which Keith Mease fabricated to fit snugly where the headlights used to be.

The Innovative Motorsports boost controller is used for not only max boost, but to adjust the boost ramps for better traction. A Computech EGT and Autometer fuel pressure datalogger also come in handy for tuning purposes.
