73 Plymouth duster question

[wupracing]

One other thing the Tail Lights must Macth the front end.
The Demon Tail lights are a total difference than any Duster Tail lights.

We went throught this is Super Stock.Had to change from a 1972 Plymouth Duster to a Dodge Demon to stay in the same Class.Change Front ends and Cut tail lights out of the Duster and instal Demon tail lights.

If you decide to change the taillights to a Demon and keep the front end, you will be limited to a '71 Demon with a high compression 340 or a '72 Demon with a low compression 340.

Side marker lights are also different between '71 and '72. I don't know how picky tech is with that or with any small differences between a '71 and '72 Demon grille.

The right 340 combo for 1970 340 with the Carter AVS carb,
The right 340 combo for 1971 340 with the Thermo-quad,
Tail-lights are also different on the Dusters,
I would say, 'can' the Demon experiment, and stay with the option on the Duster, for 70 or 71.
As for the 318 2- barrel/230HP rating in the early 70's. A 'Bad' combo
in K/S and later L/S.

Its the "LOOK" and integrity of the class. Everyone calls the class cars Bracket racing but they dont need to look like bracket cars.

'73 has to be a 340 only
'74 has to be a 360 only

The main difference between the 2 model year bodies is that a '74 has rear shock absorber-type bumper brackets. Not sure how strict NHRA is about that but NHRA regulars may know. They do help with the weight in the back since they are heavier than standard brackets used in previous years.

Myron, I have a friend who has a Demon Stocker. The car is a '71 and is run both as a '71 and a '72. When he switches engines, he also switches the grille. I'm pretty sure NHRA and IHRA are OK with the '71 side marker lights when he's running it as a '72.
