Hennessey EXORCIST ZL1 Final Edition to Mark End of Camaro Production

Hennessey Performance, the Texas-based hypercar manufacturer and high-performance vehicle builder, has announced an end-of-production limited ‘Final Edition’ series of the company’s EXORCIST Camaro ZL1 upgrades.

In stock form, the Chevrolet Camaro ZL1 has a 6.2-liter supercharged LT4 V8 rated at 650 hp and 650 lb-ft of torque. Hennessey’s technicians fit the Camaro’s pushrod V8 with a larger high-flow supercharger, high-flow air induction system and upgrade the auxiliary fuel system, fuel injectors, and fuel pump. Turning to the V8 powerplant, the cylinder heads are ported, custom HPE camshafts are fitted, and the intake valves, exhaust valves, valve springs, retainers, lifters, and pushrods are upgraded. An oversized heat exchanger is fitted for enhanced cooling, while long-tube stainless steel headers and high-flow catalytic converters improve breathing.

Additionally, the EXORCIST ‘Final Edition’ is calibrated with an HPE Engine Management software upgrade. This enhancement, along with the comprehensive overhaul of the engine, results in the LT4 engine achieving an output of 1,000 horsepower and 966 lb-ft of torque.

“Our comprehensive upgrade to the Camaro ZL1 is one of my all-time favorites,” John Hennessey, company founder and CEO, said. “The chassis, suspension, and powerplant work seamlessly together, so all the driver experiences is raw, unbridled horsepower. There’s nothing else like our EXORCIST, so we’re eager to share this special limited edition with fans of this iconic car before it’s gone forever.”

Complementing the upgraded powerplant – each engine is finished with a ‘Final Edition X of 57’ serial-numbered engine bay plaque, commemorating 57 years since the Camaro first entered production. The engine badging is accompanied by EXORCIST ‘Final Edition’ graphics on the exterior.
