When going all-out, the superior breathing of a Four-Valve modular and the lightweight of a Fox chassis is a jamming combination. Ryan Talcott broomed the engine compartment of his ’93 Cobra clean before fitting this twin-turbo 5.4 into it. With 883 rwhp, it runs mid-9s at 148 mph with a pumped AODE trans. Note how all vestiges of street equipment are gone to make room for the big engine, turbos, and their bulky plumbing. This made fitting the Navigator-sourced four-cam exponentially easier and illustrates how track-only or bare bones street cars simplify engine swaps.
