The Mustang Boss 302 is one of the pinnacles of the Mustang line, but Ford Racing has just given it even more of a boost.
The Ford Racing team decided to give the classic 5.0 liter V8 a boost. First, the tunnel ram style intake manifold was swapped for a Ford Cobra jet intake manifold. Runner cross section and plenum volume were increased to allow for even more airflow. A dual 65mm throttle body then replaced the original single 80 mm throttle body. Tor round out the intake modifications, the inlet track was then augmented with a cold air intake kit. 29 additional horsepower and 10 ft. lbs. of torque were gained via these modifications.
Next, the team replaced the camshafts on both the intake and exhaust valve-trains which achieved 1mm more lift on both shafts versus the stock configuration, as well as 3 additional degrees of duration on the intake camshaft, coupled with 27 additional degrees on the exhaust. For these modifications, the dyno measured a marked increase to 49 additional hp and 23 additional ft. lbs. of torque.
Finally, the team added 1 7/8 inch long tube headers in place of the original “shorty” design. The headers feed into new exhaust straight pipes for a gain of 19 hp and 8 ft, lbs, of torque. Cumulatively, the engine gained a total of 68 hp and 23 ft. lbs. of torque. Considering none of the additions were too extensive, yet the gains are impressive, this makes for a job well done and one fast Boss.
