Those are so cool. There was a Duster at our local track last fall with a truck engine in it. The thing sounded way different than any other Mopar at the track. What a great powerplant for a drag car. A engine designed and built to produce 700 hp at 8,000+ rpm and last for hours! You could probably get 5 years out of one at the strip with nothing more than a yearly set of plugs and a oil change!
