1972 Dodge Demon
340 - Introduced the
previous year, 1972 models featured an updated grille and interior.
The base two door coupe started at $2,316 with the 198 C.I. slant
six engine. Engine options included the 225 slant six engine a 318
two barrel V-8. Buyers looking for High Performance were offered
the "Demon 340".
The Demons 340 engine was one of
the biggest changes of 1972. With adoption of net horsepower
ratings, the high performance 340 V-8 was now rated at only 240 hp,
a "loss" of 35 hp from the previous year. Compression ratio was
dropped to 8.5:1, down from 10.5:1. Despite the hp drop the Demon
340 was still one of the best performing Dodge musclecars in the
1972 lineup. The price of the 1972 Demon 340 rose $38 from 1971.
Horsepower was down on all
Chrysler, Dodge and Plymouth engines in 1972. The 426 HEMI an 440
Six Pack engines were no longer available. Leaving the four-barrel
440 V-8 as the top big block engine rated at 280 hp. The second
hottest engine in the 1972 Chrysler lineup was the 340 magnum.
1972 was a significant year for
auto makers, new federal laws required all automobiles built to run
on low lead or no lead gasoline. This required compression ratios to
be lowered on High performance engines, including the Demon's 340
engine. All engines were now rated at SAE Net horsepower instead
brake horsepower. (SAE horsepower is the theoretical hp with all
accessories installed). 1972 would be the last year for the Dodge
Demon and Demon 340. 8700 examples of the Dodge Demon 340 were
produced in 1972.
