Numbers-Matching 440 V8: 1970 Plymouth GTX

Introduced in 1967, Plymouth GTX’s was something of a “Gentleman’s Muscle Car” in that it was more luxurious than the Road Runner which followed a year later. The letters in the name are said to stand for “Grand Touring X.” As a standalone model, the GTX was only around for five years, yet it was on three different mid-size platforms during that time. This 1970 edition is said to be a running car that has recently come out of storage. It’s going to need work, especially with the body panels, and can be found in Perryville, Missouri. The Mopar is available here on eBay where the reserve is unmet at $16,500, although you can “buy it now” for $26,000.

Belvedere-based GTX production ran from 1967 through 1971. After that, as the muscle car market started to fade, the GTX became an upscale trim option on the Road Runner. The car’s output never reached the same level as its budget-minded companion and 1970’s assemblies of under 7,800 copies compared to more than 46,000 for the Road Runner. As the senior muscle machine in the line-up, the GTX was treated to a 440 cubic-inch “Hi-Perf” V8 as standard equipment with the only upgrades being the 440 6-Pack or the 426 Hemi.

We assume the 4-barrel 440 is what’s under the hood of the seller’s car, which he has recently been able to get running again. At 107,000 miles, the motor sounds good and the automatic transmission seems okay, but the carburetor is going to need work. It’s a numbers-matching car that the seller believes is the first GTX to leave the assembly line in St. Louis for the 1970 model year. It has the Air Grabber hood which the seller believes is a-okay.

As is often the case with cars that have been sitting for years, rust is a problem. Both the quarter panels will have to be replaced and there are some holes in the trunk floor. The vinyl top is starting to peel and who knows what you might find under there. The seller has not pulled up the carpeting, so he doesn’t know the condition of the floorboards. The Deep Burnt Orange paint (FK5) may be original, but that’s a guess. Other than the passenger bucket seat, the upholstery may be good and there are no cracks in the dash. The car comes with a build sheet under the rear seat, but there’s some question as to whether it matches this Plymouth. If you buy this GTX, you may have to wait on the title which the seller says is “on the way.”

    Just amazing that it’s easier to say he or she hasn’t pulled back the carpet to look at the floors. It’s on a driveway, they haven’t looked under the car, really? I am sceptical, maybe my age

    Nice project car. I love those B bodies but the title is on the way thing would really scare me. I went through that nightmare in 1980 when I paid $2000 for a 66 Chevelle. The seller promised me that the title is on the way and while waiting to hear back from him a guy came to my house with a. 45 demanding his car back! I’d seriously look into that

    I had a 1968 and then a 1970 Plymouth Road Runner back in the day. I see these MOPARS in such disrepair and I can’t understand how someone could let these cars get in such bad shape…..

    Steve is right imo. These cars were exceptionally gorgeous from day 1. How idiots could just ignore those lines is unfathomable to me.
