2023 COPO Camaro 1004HP From 10.4L V8: Highest Powered Muscle Car Ever

By Dave Ashton

Chevrolet the iconic bowtie brand has released a limited edition 2023 COPO Camaro. The factory drag racer built for off-road use only features Chevy’s huge crate engine. All 10.35L or 632 cubic inches of V8 power, are designed to drink regular pump gas or 93 octane for full performance. In real-world terms, this equates to 1,004 hp and 876 lb-ft of torque.

To give some semblance of an idea of the power levels, the engine can produce 600 lb-ft of torque at 3,000 rpm, with the peak torque levels maxing out at 5600 RPM.
This engine shares the same basic iron block as the ZZ572 crate engines, but with a larger bore and longer stroke to accommodate the larger displacement. Fuel hits the cylinders through port injectors, pushing through to forged aluminum pistons and a forged steel crankshaft and connecting rods.
The transmission will be an ATI Racing Products TH400 3-speed automatic with a Hurst shifter, fuel injection, and Strange Engineering rear differential.

The limited edition run of muscle cars will be offered with 3 engine options. The engine previously mentioned, a 7L/427ci V8 with 470HP and a supercharged 5.7L/350ci V8 with 580HP.

The vehicles available are usually 69 units, corresponding to the original 1969 COPO Camaros which featured aluminum 427 ZL1 engines.

The history behind the limited edition run goes back to the Central Office Production Order (COPO) system run by Chevrolet for fleet vehicles. The original idea behind the COPO system was to provide utilitarian options such as different paint colors and work equipment. But, guys such as Illinois-based dealer Fred Gibb use the ordering system to drop the ZL1 427 engine into a Camaro for peak power levels.
