God I've always loved that car, what a brute. Friend of mine in college, his dad had an 86 GTS. He was at a Ford swap meet in the early 90's, maybe 90 or 91, and found a basically new zero mile 71 Boss 351 motor, which he bought and put in the car. For those not in the know, the Boss 351 was, IMO, one of the ultimate motors that Ford has ever produced. The Boss 302's and 429's got all the press and glory, but both were motors designed for the track (the 302 trans am road courses and the 429 NASCAR high speed ovals)and didn't really come into their own in daily use on the street. The Boss 351 was perfect for the street and featured 4 bolt mains, a solid lifter cam, the larger 4V port heads, 11.7:1 compression, forged pistons and rods, an aluminum intake, nodular crank, dual point distributor, and a 750 cfm carb. For many years the 1971 Boss 351 was the fastest Mustang built, second only to the Boss 429, which is impressive considering the 71-73 Stangs were the largest and heaviest years built. Unfortunately the Boss 351 only survived that one year, 1971. Anyway, my friends father found one of these motors and had it put into his Pantera, the result was simply incredible. The thing accelerated so hard it felt like my eyeballs were being driven into the back of my skull, my kind of car. Haven't talked to the guy in several years, don't know if his dad still has it. Italian exotic styling meets Ford power and reliability.
