427 V8/4-Speed! 1966 Chevrolet Impala SS

By 1966, the Super Sport was in its third year as a separate series on the Impala. A variety of engine choices were available to buyers, but in the grand scheme, only a small number of SS models came with the 427 cubic inch V8. This ’66 Impala SS appears to be numbers matching, which could be considered unusual as those big motors often found themselves transplanted elsewhere. Complete with a 4-speed transmission, this car is in Madera, California, and available here on eBay for the Buy It Now price of $15,000 (but you can also submit an offer). Note that while it does start and run, it will need a lot of work. Thanks for the tip, Larry D!

Chevrolet built 119,314 Impala Super Sports in 1966, but most of them came with a motor other than the 427. Just 3,247 full-size Chevies came with the L36 390 hp version (not just SS cars) and another 1,856 with the L72 425 hp edition (again, not only SS models). You could get an automatic with the L36, but the L72 only came with a 4-speed. The seller’s car has an L36 engine. We’re told this Chevy was purchased in California and that’s where it resides today.

Although some of the photos show a greenish tint to the car’s color, it’s wearing factory white paint with a red interior. Although the Impala looks rusty most everywhere you look, the seller says the lower body is okay. The roof is where the problems lie, above the windshield and in the A-pillars. He recommends replacing the roof and a parts car (not pictured) is provided, another SS finished in turquoise. So perhaps there is enough there to make one good car out of two.

The VIN identifies this Chevy as a real-deal SS which is important as clones and tributes seem to be everywhere, although mostly Chevelle’s, Camaro’s, and Nova’s. We’re told this car runs, even though there is no glass to look out of fore and aft. He’ll provide a video of this operation upon request. The interior has seen better days and most everything will need replacing or refurbishing. From what we can tell of the carpet-less floors, the car may indeed be okay along the bottom. The seller will consider a trade, but cash is king.

    These were really beautiful cars, just to look at. They rode nice too in standard form.

    I remember back in the day guys would install air shocks on all the impalas to fit the widest tires on them . And they would go side ways because the bar that kept the rear end centered would change so one tire stuck out on side and the other fit in the wheel well . Loved the cars !!!

      I had N 50 15s tucked in at stock height. No rubbing issues and they were both equal distance no offset.
