This 1967 Plymouth GTX Belvedere was restored 7 years ago. I have the build sheet and most importantly the numbers match. The Plymouth GTX arrived on the muscle car scene in 1967 as Plymouth’s serious contender. a hot rod version of the square Belvedere. with a Hemi V-8 option. Base motor in the GTX was the 375-hp. Super Commando 440-cid V-8. capable of 0-60 mph in 6. 8 seconds. with a quarter-mile time of 14. 6 seconds and a top speed of 121 mph. And that was when the car was equipped with an automatic transmission and not an optional 4-speed. The 426 Hemi option cost $605 extra and only 703 GTX hardtops and 17 convertibles were so equipped in 1967. Due to its high cost relative to the Plymouth Road Runner. the GTX is relatively rare today. The cars were incredibly quick. but also invariably better equipped than most other muscle cars of the era. which makes good originals worth seeking out. Hemis are the rarest of the breed
