Plymouth "Duster Demon" with history ???

I heard of Mr.Norm putting 440s in duster

Anyone that told you that was just passing along lies.
Mr Norm was a DODGE dealer. Yeah, we all group Dodge, Chrysler and Plymouth together, but back when Plymouths were a force to be reckoned with, there was some rivalry between them and Dodge.

The car in the ad appears nice, but the ad is written by someone with some incorrect info. Anyone ever heard of a Camaro Trans Am or a Pontiac Z28? It is equally silly as a Duster Demon.

Richard Petty? By 73, he was not racing a 108" wheelbase A body. These cars were never used in any NASCAR series that I ever heard of. My sources say he switched to a Charger in '72 and had some success too.
