5.4L Modular Motor Intake Manifold Test - Factory Fast Vs. Advanced Aftermarket
|
Our test motor was a modified 5.4L supplied by Sean Hyland Motorsport. The 5.4L Four-Valve motor was equipped with ported Navigator heads, SHM Stage 2 and 3 cams, and a forged rotating assembly. Loyal readers will remember that this same motor produced 1,002 hp at just over 17 psi with a twin-turbo kit from HP Performance last month. View Related Article
