When you are building a high-horsepower street machine like we are with our 1968 Plymouth Valiant, you will need to solve the problem of how to eliminate all the heat generated. The cooling system takes the brunt of the entropic energy, and in our case the stock slant-six radiator was not going to even come close. With 657 dyno-proven horsepower on tap from our 500ci low-deck Indy Cylinder Head wedge, we needed some serious cooling power. For this, we turned to one of the experts: Be Cool.

When it comes to Mopar cooling, Be Cool (www.becool.com) has several solutions in the Direct Fit Classic line, including a 400HP Direct Fit system, a 700HP Direct Fit system, and their big dog, the 1,000HP Direct fit system. In selecting our system, Be Cool felt the 700HP unit would offer enough cooling power for our car, but due to the size constraints of our big-block power plant inside the small engine bay, they decided to err on the large size with the 1,000HP system (part No. 62198, 839.99 Summit price) because it has a thinner fan package than the 700HP system.

The back story behind the 1,000HP Mopar A-body system is that Be Cool designed it originally to cool one of Ronnie Sox's Hemi-powered exhibition cars. The 32-inch wide radiator is actually about two inches wider that the inner fenderwell pinch weld area, and to drop it in, you need to trim away part of the structure. We also opted to open up the window in the core support, which gained us approximately 30 percent more exposure to the airflow slipstream, however, this is not required to make it fit—it just cools better. Installation also requires that you drill two half-inch holes in the same area for a pair of locating pins. Bottom line: If you're shy about cutting Mopar sheetmetal, you probably shouldn't have a 650HP big-block in you're a-body!

Our 1,000HP Classic Be Cool system was installed by Ron Aschtgen of Outlaw Motorsports (www.OutlawMS.com) in about 6 hours—which comes out to be closer to 3 hours after we subtract all the time we took for photography and video. We got most of the wiring complete, but we'll tackle the rest after we fix all the old wiring in the car and relocate the battery to the trunk. Speaking of which, the 1,000HP Classic system for Mopar A-body will require battery relocation, since the radiator will occupy some of the area previously taken by the battery. Later on, we will bend up some coat hangers in the shape of the radiator hoses we need, and try to match the shape with something at the parts store—we're sure we can find something, or join several together. We'll also hook up our TCI-built Torqueflite A727 to the Be Cool's built-in trans cooler once we bend up some steel trans lines. When the Violent Valiant nears completion, we'll be filling the cooling system with Be Coolant, and putting it to the test! Until we do, check out this really cool video of our installation, and look for the complete story in our June 2014 print issue!
