What is the difference between JH23G2B and JS23G2B?

[Culvers]

JH = Standard Challenger
JS = Rallye Challenger (70-71 = R/T)

Yes. In 1972 the JS was the Ralley. The only real difference to the JH was the Rallye came with the performance hood and the dummy air extractors bolted to the front fenders.

You also got the 340 as standard I think? So the 318 on that one is a suprise.

For 1973-4 they dropped the JS altogether and Ralley was just an add-on option.

strange they made a 318 car JS. So I wonder how many 318 JS`s cars
were made in 1972?

[dave-r]

I might be wrong about the 340 being standard but I thought that was the case.

318 standard on the Rallye according to the brochure. But it also states the slant six was available and I was sure the slant six was dropped for '72?

It is amazing what you can find on this message board.

18,535 JH Challengers in 1972 of which 1,267 were 340-4bbl powered.

8,128 JS Challengers of which 5,012 were 340 powered but 3,116 had the 318.

[dave-r]

Interesting to note that, out of a total of 26,663 Challengers in 1972, only 6,279 were 340 powered.

So three quarters of all people buying a Challenger in 1972 wanted a smaller engine.

Sign of the times. And what goes around comes around....

E44 NO N41 & N42

1972 JS NO A62

seems that they didn't stamped the A62 code on the tag even if it was standard on the JS model
