Looking for a custom-made show quality cooling system? How about unique decorative engraving that can be added to the top tank, like the ball-milled linear design and custom engraving shown here? Almost any design, slogan, club name, club logo, etc, can now be engraved in the top tank surface. Also available is custom anodizing in black satin for an OEM appearance, along with 16 brilliant candy colors, including polished gold. These coatings will not clog the delicate louvers or affect the radiators performance. Note the optional three interchangeable filler and top radiator hose fixtures. Mark 7 Custom Radiators are built one at a time, not on an assembly line.

The Fox body Mustangs, particularly the 5.0-liter equipped ’82 and later models, have emerged as affordable and very popular street and track performers. With great power to weight ratio, and a huge amount of aftermarket support, 500-horsepower street versions are common. Mark 7 Radiators will build you a custom aluminum radiator that will cool up to 700 HP, with the A/C running, in 100-degree temperatures. Now that’s running cool!

Mark 7 Radiators has just completed this custom-made down-flow aluminum radiator for a Hemi powered ’70 Plymouth Super Bee. The car is a restomod, so the owner wanted the radiator to look stock. Mark 7 recreated original style tanks for a factory appearance, then black anodized the radiator. The car has a remote trans cooler, so this direct fit radiator was made as a Chrysler 26-inch A/C car radiator. Since it’s equipped with a four-speed, no trans cooler provisions are included. Custom all the way, and guaranteed to cool this monster motor!

Mark 7 Radiators now has custom made or stock replacement radiators for all Mopar years, makes and models. This black anodized unit is for the 1970-’74 Dodge Challenger. 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. Custom engraving on the tank or shroud is also available. This semi-gloss black anodized unit is for a restored Challenger R/T with a built 400-CID engine and automatic trans. The owner prefers a stock appearance for this resto.

Cooling mid-Sixties muscle cars has been a problem since they were new. Certain body styles simply didn’t provide enough airflow for the original copper/brass, small-row radiators of the day. And they still don’t! This is particularly acute with big-inch engine swaps into 1964-’67 GM A-bodies. This Mark 7 aluminum radiator has been custom made for a ’64 Olds 4-4-2, which has been upgraded with a built ’70 455-cid Olds engine. The big-block is backed with a beefed up Turbo 400, so provisions for the transmission tubes are provided at the bottom, just like the factory radiator.

Mark 7 Radiators can build you a stock or custom aluminum radiator capable of cooling up to 1000 horsepower. The part shown here is for a big-block B-body Road Runner, but they can make a radiator for any year, body style, transmission or engine size you need. Custom engraving on the Mark 7 fan shroud or tank top is available. All Mark 7 Radiators are made in the USA, and can be built to your specifications in about three weeks. These are not off-the-shelf radiators.

High performance engines need high performance cooling. This natural finish aluminum radiator, from Mark 7 Radiators, is more than capable of keeping a 468 CID, 500 HP engine running on the thermostat. And that’s on a 100-degree day with the A/C running, and in slow moving street traffic. All Mark 7 aluminum radiators are custom made in the USA for your vehicle, and can be delivered to your door in just two to three weeks from ordering. 

Now you can have the look of an original style radiator AND the superior cooling benefits of aluminum. Mark 7 Radiators can build you an aluminum radiator, specifically for your vehicle, for less than most off the shelf generic radiator suppliers. So if you’re interested in the totally restored muscle car look, polished show look with engraved top tank or natural aluminum for a street machine, it’s yours. This radiator was specifically built for a big-block four-speed restomod street machine and will easily cool up to 750 HP in ambient 100-degree weather.
