The Jerrari Wagoneers are a pair of 1969 and 1977 Jeep Wagoneers built for William Fisk Harrah, founder of Harrah's Hotel and Casinos,[1] that have had their stock 360 cu in (5.9 L) AMC V8 engines replaced with a 4.4 liter V12 engine and 5-speed manual transmission from a Ferrari 365 GT.
Harrah then commissioned the first Jerrari to be built by combining a 1969 Jeep Grand Wagoneer with the engine, transmission, and front end from a Ferrari 365 GT.
He later commissioned the second Jerrari to be built for the same purpose, although this time keeping the original Jeep bodywork intact.
[6][7] The 1977 Jerrari Wagoneer's exterior was kept mostly original, with only minor changes such as headlight wipers, a bumper-mounted ice alert system, custom emblems, and license plates, the original quad-tip exhaust from the Ferrari donor car and lengthened front sheet-metal to be able to accommodate the engine.
[4] The interior received a few minor changes as well, including a Ferrari steering wheel, aftermarket gauge cluster, power mirrors, and a radar detector.
