This is a photograph of an open Car Craft magazine (October 2011 issue, page 53) laid across the engine bay of a 2003 Ford Crown Victoria. The article, 'Build a Panther: More Power (Finally)' by John McGann, documents installing a Trick Flow Specialties Twisted Wedge Top End Kit on the 2V SOHC 4.6L Modular Ford engine of a former police-package Crown Victoria project car. The text states the upgrade produced nearly 70 more horsepower and 50 more lb-ft of torque, with a baseline of 208 hp and 254 lb-ft measured at Racers' Edge Tuning in Downey, California, and 15.60-second quarter-mile timeslips. Photo captions detail engine removal (unbolting exhaust, torque converter, transmission, and motor mounts; removing the hood so the oil pan clears the core support), teardown tips (prying the heater hose from the water pump, marking timing cover stud locations, which gaskets can be reused), and an explanation of the overhead cam/roller follower/hydraulic lash adjuster arrangement. The article notes the same build applies to any SOHC 4.6 or 5.4L Ford engine in SN-95 Mustangs, Thunderbirds, Cougars, Town Cars, F-150s, and Econolines. A partially visible framed placard identifies the car as a former Car Craft project vehicle purchased by Matthew Tatosian; a battery warranty label (1000 CA / 850 CCA) is also visible.
