The MOD 4.6 in the 2003 MACH1
The powerplant that shakes the scoop and the competition is a MOD 4.6-liter, 4-valve, dual-overhead-cam V-8. The engine makes use of specially calibrated cams, a modified upper intake to accommodate the ram-air system, a heated PCV, a forged crank (cast crank in automatic transmission application) and performance exhaust manifolds combining to produce an expected output in excess of 300 horsepower. Upon completion of testing and certification, actual horsepower and torque data will be available.
Hmmmm.....more powerful 4 valve engine.

Hahaha our trucks make 300 to the wheels with two valves per cylinder! Well that was before the turbo.
