1971 FORD MUSTANG- IS BIGGER BETTER?
The Mustang had grown steadily, in size and weight, with every 2-year body change. This one was the biggest change so far, with the ’71 Mustang growing in nearly every dimension over the 1970 model, including 2 inches in added length, and 3 inches in increased width, to accommodate the massive 429 big block they planned to stuff into it. This was the first time the wheelbase had ever changed off the original 108 inches. It was stretched by an inch. The new car was available in the same 3 body styles as before, Hardtop, Fastback (which Ford called “Sportroof”), and the Convertible.
NEW MODELS & ENGINES FOR 1971
Some of the old model and sub-model lineup remained the same on the 1971, and some things got switched around. Gone was the Boss 302, both the engine and the car, replaced by the Boss 351, the car and engine, which was the hot new 351 Cleveland. The Mach 1 was back, and so was the Boss 429, again both in Sportroof bodystyles only. Nearly 3 inches of extra width was added to the ’71 Mustang to make room for the extremely wide 429 engine for the Boss 429. Prior Boss 429’s required “modified” front suspension towers to make clearance. The modifying was done with sledge hammers on the factory floor.
