1969 Mustang Mach IV exhibition dragster at SEMA 2015
Part of the Galpin Ford display part of the “Ford out front” compound at SEMA 2015 in Las Vegas was Gary Weckessen’s Mustang Mach IV exhibition dragster. Inspired by “TV” Tommy Ivo’s “Showboat,” powered by four Buick engines, Weckessen had master fabricator Kent Fuller build him his own four engine monster.
Carrying sponsorship from Galpin Ford in North Hills California the Mustang is powered by four alcohol-injected Ford 351 cubic-inch “Windsor” engines introduced in 1969, so named for the Canadian engine plant where the engines were manufactured.
Unlike Ivo’s car, the ‘Mach IV’ fed the output (estimated at 3000 horsepower) through a single clutch and transmission, and was claimed to be capable of 8-second elapsed times on the quarter mile drag strip with a top speed of over 180 miles per hour.
Probably the most unique features, which the author noticed as he photographed this monster, are the real steel chrome bumpers front and rear. Weckessen toured this car all over the United States from 1969 until 1975, and then put it in storage. The car restored for its debut at the 2013 SEMA show, is part of the Galpin Auto Sports Museum collection.
