Mark 7 Radiators has custom made or stock replacement radiators for all Mopar years, makes and model vehicles. Mark 7 will custom make a radiator to your specifications, and provide it in natural or polished aluminum or in one of 16 other custom anodized colors. This black anodized unit is for the 1970-’74 Dodge Challenger. Custom engraving on the tank or optional custom shroud is also available. This semi-gloss black anodized unit is for a restored Challenger R/T with a built 440-CID engine and 727 auto trans. The same 26-inch radiator will also fit the ’66-’73 B-bodies.

Mark 7 aluminum radiators for Mopars are each hand built for your size engine with four-gear or auto transmission. They cool more efficiently than the traditional copper/brass radiator, as aluminum transfers heat to the coolant faster. Manufactured with two 1.25-inch cores, this radiator will cool up to 750-HP in 100-degree weather with the A/C running. Mark 7 radiators are not off-the-shelf units; each is specifically built for your car or truck. The average starting price for the natural finish radiator is $650 (cost will vary with application) with anodizing slightly more. A downloadable specification sheet is available at their website.
