I agree with the 40k number as is. U code 440 Magnum cars seem to have fallen through the cracks as far as values are concerned. The should be right in the middle between a 383 car and a 440 Sixpack car, but they are closer in value to a 383 car than a V code 440 Sixpack car. The 4 speed and 4.10 Dana are a big plus, but the interior and exterior colors, ,non matching engine,as well as the mods will hold the car back. 40k still isn't bad for a non matching car that needs restoration.
