It didn't take long for the NMCA Flowmaster series to gain momentum after its season-opener in early spring. The second stop on tour is Atlanta Dragway, which sits about an hour north of the town that bears the same name. The exciting news heading into the Nitto Tire All-Star Nationals was the kickoff a brand-new class for the street legal organization: Radial Wars. The category is a virtually unlimited power-adder eliminator that puts back-half and stock suspension cars on 315 radials or 29x10.5-inch slicks. As NMCA officials describe it, the cars are so powerful (in excess of 3,500 hp) that the class is contested in the eighth-mile only. The quick-paced Radial Wars joins the rest of the NMCA program that includes 5-second Pro Mod cars, 275 Radial machines tickling the 6-second barrier at 200 mph, and several other categories that bring in hundreds of new and old muscle cars.
The biggest noisemakers in the NMCA arena of play belong to the Pro Mod class (sponsored by Kooks Custom Headers). Big-displacement nitrous engines rule the roost most of the time with powerplants that check in between 800 and 903 ci. Bobby Rahaim pushed his '69 Camaro replica into the 5.90s on his way to the Pro Mod victory. The 872ci engine comes from Reher-Morrison and while it doesn't use any traditional big-block Chevy components, we're going to pretend that it's just a steroid-enhanced version of the second-generation Mark IV engine family. The Michigan-based competitor took down the Pro Mod Mustang entry of Kevin Fiscus in the finals, 5.94 at 244 mph to the turbocharged racer's 6.14 at 242 mph.
The Mickey Thompson Tires Radial Wars class culminated in a battle of Corvettes, with Keith Berry facing of against Mark Woodruff. Both racers might share similar tastes in Chevy's baddest sports car—Berry runs a C5 Z06 while Woodruff runs a C6 ZR1—but the similarities end there. The winning C5 sports a nasty 468ci LS small-block with twin turbochargers while Woodruff's C6 packs a monster 670ci engine, also with twins. The NMCA uses a different minimum weight requirement to keep both combinations equal. The top Radial Wars cars run in the 4.30-4.40 range with speeds in excess of 180 mph through just 660 feet of race track. Berry took down Woodruff in the finals with a 4.40 at 180 mph to a slower 4.79 at 161 mph.
Other notable performances turned in by Chevy racers included a win in the tough Edelbrock Xtreme Street category for Bill Trovato and his '10 Camaro. The fifth-generation Camaro gets motivated to 170-plus mph speeds on true 10.5-inch tires thanks to a 440ci LSX engine with LS7 heads, carburetor intake manifold, and a single stage of nitrous oxide. Trovato lined up and beat the Chevy-powered Mustang of Dan Kroll in one of the tightest races of the final rounds—8.12 at 171 mph to Kroll's impressive 8.14 at 172 mph. Xtreme Street was revamped over the winter and is NMCA's fastest growing heads-up class thanks to the conventional powerplants and true 10.5-inch tires required for competition. The times hover in the high 7/low 8-second realm with these mild looking race cars.
One of our favorite race cars in NMCA competition, the '71 Caprice of Andy Warren, sat on top of the Detroit Locker-sponsored Nostalgia Muscle Car index category. The big-block Chevy-powered leadsled knocked off a 10.51 on a 10.50 index to defend the Bow Tie honor against the '68 Mustang of Bryan Parker, who happened to go red in the finals, handing the win to Warren. Jeff Rudolph was another Chevy racer who pushed his iron into the winner's circle. The MagnaFuel Open Comp racer used his '70 Nova to beat the modern '04 Pontiac GTO of Keith Vaughn. The Nova won by way of a 9.98 on a 9.96 index.
