Several unsuspecting mouths were left agape when Chevrolet revealed its COPO Camaro Concept at this year’s SEMA Show last month in Las Vegas. The proposed NHRA drag racer is the answer to the Mustang Cobra JET offered by Ford, if only GM gave it the official green light. Despite it still falling under the “concept” category, Chevy announced another engine variant to the straight-line sprinter.
Falling under the 5.3L (327 cubic inches) category and boasting a huge 4.0L Whipple supercharger, preliminary statistics pin the engine with enough velocity to propel the COPO Camaro through the quarter-mile in 9 seconds or less. In NHRA talk, that qualifies it for Super Stock class. The prototype engine would *hypothetically* be flanked by a 7.0L (427 cubic-inch) LS7 designed for A Stock and a less potent 5.3L supercharged engine for AA Stock racing. If you ask us, it seems that Chevy has gone deep enough here to drop the whole “proposed” and “concept” wording, and just launch the damn thing, with neck spraining velocity.
