1967-1968 Ford Mustang – the Legendary Mustang

Ford had produced a phenomenal almost 1.3 million Mustangs from Spring of 1964 to the end of the 1966 model year. When Ford released an updated Mustang for 1967, it was a gamble. If Ford didn’t get the updated styling right, it would have seriously impacted sales especially considering that 1967 was the year when the Chevrolet Camaro and Pontiac Firebird first entered the market to compete with the Mustang. Even though 1967 Camaro production was an incredible 285,748 units and 1967 Firebird production was 82,560 units, the Mustang outsold both of them combined, with total 1967 Mustang production being 472,121 units which proved the updated Mustang was a big hit. However due to the new competition Mustang production had dropped from the 1966 Mustang’s production total of 607,568 units which was Mustang’s highest volume production model year ever. Had the Camaro and Firebird not debuted in 1967, there was a very good chance 1967 Mustang production would have surpassed 1966 Mustang production. Not to mention staring in 1967 Ford gave its Mercury division a version of the Mustang called the Cougar. With 1967 Cougar production being 150,893 units, its a safe assumption it also stole potential buyers away from the 1967 Mustang.

The 1967 Mustang like its predecessor was offered in three different configurations: 2-door coupe, 2-door fastback, and 2-door convertible. The biggest change for 1967 was the exterior styling. Though the general lines of the 1964 ½ – 1966 Mustang were still visible with the 1967 Mustang, the softer elegant styling of the 1964 ½ – 1966 Mustang was now replaced with an overall tougher and more gritty look especially in the frontend. The twin headlights remained but the front grille was now more angular and was larger in size. The rear quarter panels now had non-functional twin body colored air inlets right behind the side doors. The rear taillight area was now concave with larger vertical taillights that were also concave. Staring in 1967 the slope of the fastback’s roofline now went all the way back to the rear taillight area. The previous bowed rear fastback window was now replaced with almost flat rear fastback window. Overall the 1967 Mustang was slightly wider, slightly longer, and slightly taller than its predecessor. Only the 108 inch wheelbase was the same as its predecessor.

Ford would carryover the successful styling of the 1967 Mustang to 1968 virtually unchanged with only the very slightest changes. The most noticeable of which was the replacement of the rear quarter panel side vents with a thin vertical chrome trim piece. The Mustang for 1968 was still the best selling car in the pony car market segment the Mustang had created back in 1964, however for 1968 the competition was getting more fierce and numerous. For instance AMC released the Javelin for 1968 and Plymouth by 1968 had evolved its Barracuda into formidable competition for the Mustang. With this is in mind the 1968 Mustang’s total production of 317,404 units was still phenomenal. For 1969, the Mustang would undergo a major exterior redesign.

The Mustang’s interior for 1967-1968 had evolved nicely from its predecessor. The dashboard layout, optional bucket seats, and other interior appointments had improved but the general overall design of the 1964 1/2 – 1966 Mustang was still visible in the 1967-1968 Mustang’s interior. For the money it was one of the best looking new car interiors your were going to find for 1967-1968.

One big necessary change Ford made to the Mustang for 1967 was that it expanded the space in the engine bay to accommodate a big-block V8 engine. When Ford engineers designed the original Mustang they never expected the Mustang would need a engine more powerful than a small-block V8. However by 1967, the Mustang’s main competitor the Camaro could be equipped with a 396 cubic-inch big-block V8, so it was essential that the Mustang also have a big-block V8 option. For 1967-1968, Ford’s big-block 390 cubic-inch V8 which was rated at 320 gross horsepower for 1967 and 325 gross horsepower for 1968, became the Mustang’s mainstay big-block V8 during these model years. This 390 V8 was equipped with a 4-barrel carburetor and it was known as the S-code 390 V8. Interesting to note Ford also offered two very rare different 2-barrel carbureted versions of the 390 in the 1968 Mustang called the X-code and Y-code, both had horsepower ratings considerably lower than the S-code. When the S-code 390 V8 powered Mustang had the optional GT or GTA package, it really looked the the part of a true performance car. However when the Mustang transitioned into a legendary performance car was when the big-block 428 cubic-inch Cobra Jet V8 was offered as an option during the 1968 model year. It had a factory rating of 335 gross horsepower which was very underrated, true engine output was at least 20% more, somewhere around 410 gross horsepower. Hot Rod magazine back in the day obtained 0-60 mph in 5.9 seconds and the quarter mile in 13.56 seconds at 106.64 mph which showed the world the 1968 Mustang with the 428 Cobra Jet V8 was one of the fastest accelerating muscle cars of this era.

The Mustang was also available with other V8 engine options for 1967. For 1967, a small-block 289 cubic-inch V8 was available in three different output levels – 200, 225, and 271 gross horsepower. Only a 195 gross horsepower 289 V8 was available for the first few months of the 1968 model year. There was a new small-block 302 cubic-inch V8 which was available for 1968 in two output levels: 210 and 230 gross-horsepower. The standard engine in the 1967-1968 Mustang was the 200 cubic-inch straight-six cylinder engine which was rated at 120 gross-horsepower.

The low volume 1967-1968 Shelby GT350 and GT500 Mustangs were the ultimate performance Mustangs. The 1967 Shelby GT350 was equipped with a 306 gross horsepower 289 cubic-inch V8 and the 1968 Shelby GT350 was equipped with a 250 gross horsepower 302 cubic-inch V8. Shelby offered an optional Paxton supercharger for both of these GT350 engines which provided a nice horsepower boost. The 1967-1968 Shelby GT500 was equipped with a 355 gross horsepower 428 cubic-inch V8. The 1968 Shelby GT500 KR was powered by the 428 Cobra Jet V8, and just like the 1968 Mustang equipped with the same engine, it was factory rated at 335 gross horsepower but in reality generated around 410 gross horsepower.

Ford’s 1967 update of the Mustang proved to be a big success. The 1967-1968 Mustang may have had a short production life but it had a big impact on Mustang fans. Overall it was a great looking and very sporty car which offered a lot for the money. However its biggest impact was that it was the first Mustang to prove the Mustang could be a true high performance car. Ford releasing the 760 net horsepower 2020 Ford Mustang Shelby GT500 was due to what the 1967-1968 Mustang started over a half a century ago. The 1964 1/2 -1966 Mustang may have started the Mustang phenomenon but it was the 1967-1968 Mustang that made the Mustang a legend.
