Well, the company had nothing to do with Plymouth or the Chrysler Division like Shelby did with Ford. Not the same no way, no how, and you can give your business a name and have maybe 3 people involved and put parts on a car but there are no brochures from Chrysler anywhere that you could buy a car like that. The cars were maybe '69 Formula S Barracuda's 340 and 383's. The 440 was not an M code that they butchered, but rather a 440 shoved into a 340 or 383 car.
