Horse Sense:
J.R. Heuring is no stranger to drag racing. He has competed with an IHRA mountain-motor Pro Stock Ford, covering the quarter-mile in 6.85 seconds at more than 203 mph!

There is something so basically evil about black 5.0 Mustang coupes-simple in design, devastating in performance, and a color that fits their purposeful, nondescript attitude. They're all mean, but this one stands out from the crowd.

We'll begin by saying that J.R. Heuring has put together one of the nicest Mustangs you will ever see. There are so many custom tricks, so many hand-fitted, one-off pieces, and so many hours spent on things that really don't need to be there that the whole package comes off as a flowing, 146-mph work of art. While we have some great pictures of the car, you will never see it all. In fact, after an up-close tour of the car with J.R. as our guide, we walked away boggled by the attention to everything. We had to make a mental checklist just to realize how "top-to-bottom" this thing really is.

J.R. and Ken Misun painted the $50 beater DuPont Base Clear Black with racing stripes over the 4-inch cowl hood and Next Generation Race Cars' rear wing. Next Generation's Eric Miller and Chris Chalkey are responsible for the suspension, which provides J.R. with a 1.34-second kick in the rump to the 60-foot line. In the rear, custom ladder bars hang a 9-inch Ford rearend with a Strange Ultra Case, 5.43 gears(!), and Strange 40-spline gun-drilled axles. Next Generation also installed the rear sway bar, the frame connectors, and the K-member/A-arm arrangement in the front. QA1 struts with Hypercoil springs in the front work with Strange double-adjustable rear shocks to plant the 28x10.5-inch M/T slicks. The brakes are from Strange, while the rims are from Holeshot.

But the best part is, it's not for show. The bulk of the custom items we'll tell you about make this a better race car too.

This car started life with J.R. as a $50 junker that he took in on trade at his family's dealership, Paul Heuring Ford. Eric Miller and Chris Chalkey of Next Generation Race Cars (Streator, Illinois) went with a full-on, chrome-moly cage to prepare the little black war wagon for the ravages of Hot Street. They also fabricated the 9-inch rear, the weight box, the rear spoiler, the ladder bars, the headers and exhaust, the K-member, the control arms, the sway bars, and countless other components on the car. The majority of these items are handmade pieces, custom to J.R.'s application. Working with Ken Misun, J.R. did the body repairs, preparation, and paint. Each mirror-finished piece on this car has been hand-buffed by the two of them.

Every Hot Street Mustang is a rolling billboard for the creator of the beast that lies under the hood. This one carries a Cliff Moore (of Jon Kaase Racing Engines) small-block that rocks the house past 10,000 rpm and carries this 3,200-pound car through the traps at almost 150 mph. Combine that power with a Ram clutch and a G-Force five-speed, and you have some magic happening. Along with his dad (aka Big-D) and his wife, Amy, J.R. seems poised to challenge the best in NMRA Hot Street. With the off-season ahead of him, he has enough time to regroup, study all the data logged into his Race-Pak Data Acquisition system, and prepare for the '03 Hot Street season.

So, is this is the baddest black notchback in the country? It sure comes close. There are faster examples, but none of them bring the total package to the starting line like J.R.'s basic black bomber.

Nothing less than 750-plus horses of Jon Kaase Racing Engines' finest will do for J.R. and his black coupe. The 355ci monster consists of a 4.080-inch bore Ford Racing Performance Parts R302 block, 3.4-inch-stroke Sonny Bryant billet steel crankshaft, and aluminum GRP rods swinging 14.5:1 compression JE pistons. Jon Kaase ported the Edelbrock Victor heads and stuffed them with 2.200-inch intake and 1.625-inch exhaust valves, Manley valvesprings, and Jesel rocker arms. The L.S.M. camshaft is described as "big" on our tech sheet. The intake is an Edelbrock Super Victor with a 4150 Holley by C.F.M. The fuel system is backed by a Magna-Flow fuel pump and Aeroquip lines with a MagnaFlow pressure regulator.

Now this is a race car! The Long shifter poking through the floor directs the action of the G-Force five-speed trans, while the Ram clutch and custom aluminum driveshaft do their thing. Auto Meter gauges and tach, along with a set of Corbeau seats, add to the atmosphere. Next Generation did up the chrome-moly Funny Car cage-it's mint!

In a sea of outstanding NMRA Edelbrock Hot Street cars, J.R.'s flawless '93 LX coupe stands out even though it's awash in black. With a best pass of 9.33 seconds at more than 146 mph, it stands out performance-wise too.

From left to right are Ken Misun, J.R. Heuring, Eric Miller, and Chris Chalkey--which goes to show it takes a team effort to field a competitive Hot Street racer.
