1972 Dodge Demon GSS

1972 Dodge Demon GSS

"Mr. Norm, ever the performance promoter, rightly figured the low-compression 340 was ripe for forced induction. Just pack more air into the manifold and feed in extra fuel, and you'd be good for one last go-round. So this juvenile delinquent was further corrupted by a centrifugal supercharger, supplied by Joe Granatelli and installed by hot-shoe Gary Dyer. With a beltdriven Paxton puffer, plus a modified fuel pump and pressure regulator, the output ballooned to a somewhat respectable 360 horses. Compared with its fellow gangstas, that number might seem a bit like bringing a knife to a gunfight. But there was a key formula in its favor: the power-to-weight equation. Like the L79-powered Chevy II, the Demon was a cookie tin stuffed with trouble. Stomp the go-pedal, and you could catch those burly big-blocks napping at the line."

Thought you would all appreciate this car. I never saw one before.

Very Cool Mopar.....

Yes, in 71 the Mr. Norm GSS Demon had 3x2 carburetion on the 340 and in 72 they went to the supercharger. Nice car!

I'm a big 71-72 Demon fan. Kind of like the Duster and Dart's cooler, meaner cousin (in looks anyway). But, all 3 are awesome with a 340, 440 or Hemi.

Anybody know if this was a 340-275HP engine with 3 deuces fitted or was it the 1970 TA-AAR engine?

The 1971 GSS was a comprehensive package based on the Demon 340. The transformation began with the installation of a high-rise 1970 Six Pack-style intake manifold with triple Holley 2-barrel carburetion and an aluminum Ford Tri Power air cleaner, competition-grade fuel and oil pumps and performance oil filter.
