Performance Tiger Unleashed
Detroit, Mich/Chevrolet.com — The legendary Camaro Z/28 is back for the 2014 model year. Originally introduced in 1967, the Camaro Z/28 was designed specifically to compete in the Sports Car Club of America’s Trans-Am 2 class. Lightweight, nimble and incredibly powerful, the original Z/28 was designed ideally for road racing. The 2014 Z/28 carries the same racing credentials.
A hand-assembled LS7 engine powers the Camaro Z/28, boasting an incredible 505 horsepower and 481 lb.-ft. of torque, making it the most powerful normally aspirated regular production small block V8 ever. The highest-quality parts and precision assembly elevate the redline level to 7000 rpm.
The LS7 is mated to a TREMEC® TR-6060 6-speed manual gearbox that features close-ratio gearing – optimized for the engine’s power characteristics. The TREMEC is coupled with a 5.1:1-ratio short-throw shifter to ensure quick and precise shifts.
The manual gearbox is packed with the same ratios as in the Camaro ZL1, but the Z/28’s final-drive is 3.91:1 versus the ZL1’s 3.73. The engine features titanium rods and intake valves, a forged-steel crank, hydroformed exhaust headers, and CNC-ported heads. It inhales through a cold-air intake and exhales via a dual-mode exhaust system with large-diameter pipes. All engine and gearbox cooling systems are standard, as they are on the ZL1.
Design features of the TR-6060 include a combination of double-cone and triple-cone synchronizers on all gears. Anti-friction ball struts and fine-pitch splines provide reduced friction between components. A spring loaded anti-friction roller, in combination with broach forward and reverse detent grooves on the mainshaft provide precise control of shift detents and a positive shift feel.
