What is a Dart GTS or Swinger 340?

Quick Answer
The GTS was the Dart's performance flagship from 1968 to 1969, standard with the 340 V8 and available with 383 and even 440 big-blocks. The GTS nameplate first appeared late in 1967 with a 383. When the GTS ended, the 1970 Swinger 340 became the affordable muscle Dart, with a 275 hp 340, functional hood scoops, and front disc brakes.

These are the attainable muscle Darts.

GTS (1968-1969)

The flagship, with the high-revving 340 standard and big-block 383/440 options.

Swinger 340 (1970)

The budget brawler: a 275 hp 340, bumblebee stripe, hood scoops, and discs, a lot of muscle for the money.

Buyer's note

340 and big-block cars are cloned from slant-six Darts; verify the engine and codes.
