400 Tri-Power: 1966 Pontiac GTO

Disclosure: This site may receive compensation from some link clicks and purchases.

I am typically pretty disappointed when I raise the hood of a new car. Manufacturers have developed the act of hiding engines under layers of plastic into an art form, and the difference between a basic powerplant and one offering performance gains is often as simple as plugging a new chip into an engine management system. However, scouring the engine bay of this GTO leaves no doubt that we’re dealing with something special. Any car featuring a Tri-Power setup will offer exceptional performance, which is the case with this 1966 Pontiac GTO. Its presentation is hard to fault, and it would be ideal for enthusiasts seeking a high-end driver where originality isn’t a deciding factor. The seller is prepared to send this classic to a new home, listing the GTO here on Craigslist in Okanagan Falls, British Columbia, Canada. I must say a big thank you to Barn Finder Scott for spotting an American icon that could be yours for $51,000.

The 1966 model year was significant in the production life of the Pontiac GTO, with the badge receiving standalone model status after spending its first two years as an options package. This car rolled off the line that year, with the first owner choosing Montero Red as their preferred color. The seller indicates that it received a single repaint in that shade, and with thirty-five years having elapsed since, the lack of deterioration confirms that the work was completed to a high standard. I am sure that close inspection will reveal paint chips and imperfections, but there are none visible in the supplied photos. It holds a mirror shine, with the positive impression heightened by the seemingly flawless trim. The panels are laser-straight, and rust doesn’t appear to be a concern for potential buyers. The seller states that this car retains all of its original steel, suggesting that there is no history of accident damage or other repairs. The glass is clear, and the wheels are free from stains and marks.

Every GTO that left the factory in 1966 featured a 389ci V8 under the hood. None of these motors were automotive wimps, and with even the entry-level version delivering 335hp, the GTO cemented its place in history as a genuine muscle car. It is unclear whether this car originally featured the Tri-Power setup we find today, but the listing suggests that was the case. Purists will be disappointed to learn that this classic is no longer numbers-matching. The 389 has made way for a 400ci V8 of unknown origin, while the four-speed manual was swapped for a new five-speed Tremec that should give the GTO longer legs on the open road. However, it isn’t all bad news for those focused on originality because the seller includes the factory transmission, linkages, shifter, and driveshaft. Therefore, sourcing another 389 could allow the buyer to return this Pontiac to its original form. Those who seek a high-end driver will welcome the news that this GTO runs and drives like new and is a turnkey proposition for its new owner.

The seller states that this GTO’s interior is almost completely original, although they don’t specify what items may have been replaced. Its presentation is as impressive as the exterior, with no evidence of wear or other problems. The Black vinyl provides a striking contrast to the Red paint, with the faux woodgrain adding a classy touch. It isn’t loaded with options, although the buyer receives a console, a factory tach, and an AM radio.

While some enthusiasts focus on classics that are original and unmolested, others are willing to compromise if the vehicle in question is a modified high-end driver. This 1966 Pontiac GTO falls neatly into the second category, seeming to need nothing but a new home. The seller’s decision to include some of the removed parts could allow the buyer to return the car to its factory form if they can locate a date-correct engine. Would you do that, or would you enjoy all that this GTO offers in its current form?

    This is one nice Goat. My favorite year too. My older brother had a ’66 and I always admired it. The upgrades on this one make perfect sense to me too. Having the tripower setup in a 400 was a great move. I completely agree with Stan, I wouldn’t touch a thing. Just drive it with a huge smile on my face from ear to ear running it through the gears listening to that 400.
    Very nice find Adam, I enjoyed it.

    And if it’s CAD$51,000 it works out to (as of Friday) US$36,800. 🤔👍🏻

    What year 400? A 1976 low compression version has about half the horsepower of a 1966 326 and might not be able to get out of it’s own way lol.

      The horsepower numbers would be deceiving since ratings went from gross to net in 1972. If the engine was a mid-70’s smog motor, there isn’t much reason to believe it would have been installed in this car in its stock configuration.

    I seriously doubt that given the modifications to this cutie that the owner/ builder would opt for mid-seventies 400. Nice car.

    This beauty reminds me of high school in the sixties. All I could afford at the time was a Pontiac Catalina. I’ve always thought the 66 GTO was Pontiac’s best. Plus this one is red!
    I’m certainly tempted but I just bought a pickup truck this week and I’m sure my wife would kick me out if I bought this too.
    Somebody is going to get a real nice car.

    With this Goat’s born-with paint, a glossy Montero Red, it just begs for some proper rubber!….which should be a nice set of redlines!

    Doesn’t seem to make sense to spend time and money to find and maybe. rebuild a, 389 when it will still not be the original engine I don’t see how it would increase the value over the 400

    I have to admit a red 65-67 GTO is my favorite especially with black interior with a 4 spd. Is definitely a winner.
    I especially like the stock wheels.
    I had a friend in high school that had a red 65 GTO convertible 389 4spd. I loved riding in that car.
