1964 impala ss / 409 / 425




The Impala Super Sport 409 was first offered in 1961. By 1964, the 409 maxed at 425 hp, which included dual 4-barrel carbs, dual exhausts, a high-lift camshaft and a package up-charge of $484 to the Impala base price. 1965 was the last year of 409 production at the Tonawanda, NY plant, but peak horsepower in '65 was 400.  Thus, the ‘63 and '64 409/425s remained the most powerful of all 409s ever produced.


In ’64, two smaller hp 409s were offered at 340 & 400hp respectively. Four-speed transmissions were mandatory with the two top engines. 409s also came standard with padded dash interior.


Though large & heavy, the ’64 Impala SS 409/425 was capable of a 0-60 mph time of 7.5 seconds and a 15.3 quarter mile. Production of the SS 409 in 1964 was half the previous year, making them harder to find today.



Purchased in California in late 2012, it is a numbers matching radio delete vehicle. It had a frame-off restoration in the months preceding its trip to Texas. It is equipped with power steering, deluxe steering wheel and rare tilt wheel option.


It received a show quality new tuxedo black re-paint in early 2013.





The Chevrolet Impala Super Sport began in 1961 as a trim option. But in 1964, it became a separate and unique model in the Chevy line up.


The Chevy 409 was immortalized in song when, in 1962, The Beach Boys hit record opined about ‘my 4-Speed, Dual Quad, PosiTraction 409...’


The ’64 Super Sport was offered only as a two door hardtop or convertible. And with a price between $2,840 and $3,200, it was Chevy’s second most expensive offering that year.  Only the Corvette had a higher MSRP.
