Deciding on major components of a project car is generally pretty easy. We decided on the Kaase 427 and Tremec Magnum for Hypersilver in the first meeting about the project. And other major components usually just fall into place, like the obvious choice to go with the Centerforce twin-disc clutch and Moser M9 rearend. But when it comes to planning out the details, it's easy to miss things, especially an all-out build like Hypersilver.

Even when planning out a weekend engine swap, many miss this golden opportunity to upgrade the radiator and front engine dress. And since engine swaps are usually done on higher-mileage Stangs, there are even more reasons to consider replacing your old, worn-out accessories, and clogged or inefficient radiator. The last thing you want is to overheat your new or refreshed engine—and why clutter up the front of a fresh, clean engine with old stock components?

March On

One solution is a serpentine conversion kit from March Performance Pulleys. What began as an underdrive pulley company over 25 years ago has progressed to offer a full line of pulleys, brackets, pulley systems, and complete serpentine conversion kits. Included in March's line of conversion kits for small-block Ford engines, like our 427W for Hypersilver, is the Sport Track, Style Track, and Revolver series.

The Revolver, the company's latest addition, most closely resembles the Borla Induction cross-ram intake manifold of our Jon Kaase Racing Engines small-block, so we opted for it in a natural finish. The kit includes the main bracket, hardware, 105-amp alternator, chrome A/C compressor, water pump, timing cover, crank pulley, and tensioning tool. The power steering pump and reservoir can be added on as separate part numbers.

In a situation like ours, where we started with a bare shell, or if you're doing an engine swap, the complete serpentine system is ideal. All of the components necessary for the front engine dress are included, down to the last bolt. So, whether you are upgrading your daily driver or building an all-out show car, March Performance has what you need. It even offers kits for Coyotes.

Cool It

When it comes to cooling, make no mistake that cutting corners is a bad idea. Anytime you upgrade your engine's performance (even something as simple as a camshaft swap) your Stang's cooling system may need to be upgraded. Especially when it comes to Fox-bodies, and their single-core radiators and clutch fan cooling. Aluminum radiators have been a popular swap for Fox owners since 5-liter performance began, but until recently, there wasn't a viable bolt-in option for a complete cooling upgrade.

Enter Flex-a-lite, who just launched a Fox-body radiator/fan combination kit (PN 52185, $1,020.13). This all-inclusive, direct bolt-in kit is made in the USA and features a massive two-core aluminum core, a durable mounting kit, and a massive 15-inch Black Magic electric fan (3,300 cfm). It also comes with a fan controller, which can be programmed to turn the fan on at a certain temperature, or when the A/C compressor is turned on. A matching overflow tank is also included, along with mounting hardware.

In our case, though, we decided to give Hypersilver a unique look by opting for AN hoses instead of the typical rubber clamp-on radiator hoses. To achieve this, we special-ordered our Flex-a-lite radiator (you can too!) with AN -20 fittings. This also required a special thermostat housing and inlet on the water pump. To solve the thermostat housing problem, we turned to CSR Performance for one of its aluminum water necks (PN 9110AN20; $139.95), complete with AN -20 fitting built in.

While we were at it, we also opted for a Meziere electric water pump. Though not necessary for our particular application, we wanted to merely free up some horsepower and have the ability to circulate water in the cooling system while the engine is not running. The pump we chose (PN WP374, $638.92) is for '94-up 5.0L and 5.8L Windsors, which is the pump that the March kit requires. We also ordered up one of Meziere's screw-in AN -20 fittings (WN0041S, $21.30).

To connect the dots, we turned to Earl's Performance for a length of its Pro-Lite 350 AN hose and black anodized fittings to match.

01-02. For the front of our Jon Kaase Racing Engines 427, we turned to March Performance for one of its Revolver full serpentine conversion kits. This prevented us from having to piece together a stock-style system, and it looks better as well.

03. The centerpiece of the kit is the main bracket. This solid piece of billet aluminum provides a rigid mount for all of the accessories to mount. It is clear anodized to keep it looking new for years to come.

04-05. The Meziere electric water pump that we chose wasn’t a necessity since the March kit came with a mechanical pump, but we like the idea of being able to operate the pump while the engine is off.

06. Here, Darrell Kunda installs the March kit and Meziere pump.

07. Next was the cooling system. Kunda then installed the Flex-a-lite radiator/fan combo and Earl’s AN -20 hoses.

08. He then installed the Scott Rod Fabrications bumper to radiator support filler panel.

09. Here’s our engine bay complete. See how a few properly chosen accessories can make all the difference?
