    Cool An appreciation for the A-body muscle cars of the late 60s and early 70s

    An appreciation for the A-body muscle cars of the late 60s and early 70s

    Posted on August 2, 2012 by PeteRizzo


    The GM A-body frame has underpinned many of the most storied nameplates in muscle car history. My favorite incarnations of the platform were the first- and second-generation frames, developed in 1964 and 1968, respectively, when the A-body served as a base for not only the companies most popular medium-sized coupes, but also many of the meanest rides to ever come out of the GM stable.

    These RWD monsters had plenty of space for a huge engine to sit comfortably on a taut frame. It was on this platform that many car enthusiasts recognize the first real muscle car was created.

    The 'Goat' is born, and it's a screamer
    GM had originally placed a 330ci restriction on the V8s allowed in its A-body models when they went into production in 1964. Pontiac found a way around the restriction by selling a 389ci block in what it marketed as a limited production version of the Le Mans coupe, called the GTO.

    After the limited production GTO became a blockbuster for the Pontiac label, the big brass at GM saw the potential allowing bigger engines could have in attracting increasingly speed-hungry consumers into showrooms.

    A-bodies take their place as the leaders of the pack
    The engines only got bigger for cars on this platform, as the second-generation models readied for battle with the giant Mopar V8s dominating at drag strips across the country.

    In 1970, Chevy set the benchmark all other muscle cars would have to live up to when it dropped a massive 454ci LS6 big block V8 under the hood of the Chevelle SS the biggest production engine ever available in a hot rod.

    These coupes were popular because they offered great performance at a reasonable price. These two factors were accomplished because of the economic success of platform sharing among brands, but also, counter to that notion, strong brand identity at the time.

    Friendly competition breeds a beautiful ride

    When A-Bodies reigned in the 60s and 70s, Olds, Buick, Pontiac and Chevy all produced their own engines, and in many ways were in competition with each other. The Olds 442 was created largely in response to the brand wanting some of the sales Pontiac won from the GTO. This friendly competition sparked stronger engines and better designs across the board at GM.

    This practice largely died when value-engineering came into fashion in the late 70's, 80s and 90s. This was when sweet rides with big engines and sweet looks made way for clones like the Cavalier and Sunfire, or the Grand Am and Alero, that ultimately led to the death of some once great nameplates
