1966 Chevrolet Impala SS Resting in a Garage Conceals Unexpected Small-Block and Big-Block Delights

Sales of Chevrolet’s Impala reached a whole new level in 1965 when the car became the first nameplate after World War II to sell more than 1 million units in a single year.

The record wasn’t surprising for many people, the GM brand included. After its debut in 1958 as the top Bel Air version, Impala continued to evolve with every new model year, eventually becoming the full-size Chevrolet spearheading General Motors’ sales.

1966 witnessed the first decline, not necessarily because Impala was no longer a compelling product but primarily due to Chevrolet promoting the Caprice as a standalone series.

Caprice helped boost Impala sales in 1965, so when it embraced its path a year later, it cannibalized its parent model.


A 1966 Impala SS parked in a garage for many years is now fighting for survival, hoping to impress its Internet fans with a solid condition and a rare powerplant offering. The car has a 283 (4.7-liter) V8 currently installed in the engine bay, but the seller also offers a 427 big-block unit for a hefty upgrade.

The listing doesn’t address the most important questions, so it’s impossible to tell if the car continues to be complete and original. Based on the images shared by eBay seller myronbeck, most parts are still there, though they don’t exhibit their best shape.

For example, the new owner must patch the lower rear driver quarter, replace the floor pans, and do more metal work to bring the body to a tip-top shape. The rust isn’t surprising, as the car has been sitting in a garage, almost buried under all kinds of boxes and other stuff.

The interior looks in good condition, and the seats, in particular, don’t require any major fixes. I didn’t notice any major rips or tears, but potential buyers should still check out the car in person inside, outside, and under the hood. Without a doubt, installing the 427 is a very tempting idea, but the owner will decide if they stick with the original unit or perform an engine swap to get a more thrilling experience behind the wheel.


The Impala SS is available on eBay for $15,000, but the seller has also enabled the Make Offer button. If you have another deal in mind, you should contact them to discuss the details, though don’t expect the price to drop too much. The seller is willing to trade this Impala for a 1970 Chevelle SS.

Otherwise, you can see the vehicle in person in Warren, Michigan, and a trailer will help you take it home if you decide to purchase it. The listing will expire in 28 days if nobody triggers the Buy It Now option until then
