As you may know already, the dealerships-created performance packages are considered an important part of Chevrolet’s muscle car heritage. Names like Yenko, Nickey, Berger and others, created the legendary COPO Camaros of the late 1960s.
And now here is the good news: DeNooyer Chevrolet in New York and Georgia’s NeSmith Chevrolet dealers rekindled the concept of using Chevrolet’s own parts in order to create specialty Camaros.
For example, DeNooyer used GM Performance Parts’ (GMPP) LSX454 crate engine (part number 19244611) to build a modern 454 engine for the Chevrolet Camaro SS, while NeSmith installed the supercharged LS9 engine from the Corvette ZR1 into their Camaro.
Both cars are featured on the cover the 2011 GM Performance Parts catalog. The DeNooyer 454 Camaro, dubbed the HTR-SS454 (named for partner Redline Motorsports' owner Howard Tanner), takes the GMPP LSX454 crate engine and adds a port fuel injection system to its LS7-style LSX six-bolt cylinder heads.
Other improvements include a front end accessory drive system, a custom flywheel and ZR1 clutch matched to the six-speed manual transmission.
The engine delivers an impressive 520 horsepower and 530 lb.-ft. of torque at the rear wheels, or right about the 620-hp/590-lb.-ft. estimates from GMPP for the basic crate engine. In order to handle this amount of power, the car also received stronger axles and stiffer bushings throughout.
NeSmith’s LS9-powered “Storm” Camaro is powered by the impressive engine found on the Corvette ZR1 and delivers an impressive 700 hp. As expected, the car features stronger axles and a Baer brake system featuring six-piston calipers, front and rear.
