But do not count the Z/28 dead. To the contrary, Chevy is patiently saving its most vaunted muscle-car badge for the next bullet: a Camaro with 700 or more naturally aspirated horsepower and a chassis capable of spanking the other pony cars at the road course of their choosing. Getting there will take a few more months. It remains a distinct possibility that the Z/28 could use a 750-ish-hp version of the supercharged pushrod small-block V-8 slated for the 2018 C7 Corvette ZR1. But tantalizingly, as we speak, GM engine dynos already are revving the latest and what should be the greatest small-block V-8 ever conceived. Breaking cleanly from Ed Cole’s 1950s brilliance, the coming LT6 and LT7 designs finally will dispense with pushrods and two-valve combustion chambers.
We’re expecting this new engine family to combine aluminum block and head construction, dual overhead camshafts, four-valve combustion chambers, direct (possibly in combination with port) fuel injection, titanium connecting rods, and a flat crankshaft, with approximately 5.5 liters of displacement to produce the target power. Need we remind you that most of those specs also fit a bored-and-stroked Ferrari 458 Italia V-8? Peel your ears to hear Pavarotti serenading from heaven. The twin-turbo LT7 version will trade some of the exhaust aria for additional power, à la Ferrari 488GTB.
These engines eventually will power the Camaros and Corvettes of your dreams as well as the hottest Cadillacs in GM’s arsenal. We’re estimating the sequence could begin with a Z/28 for the 2019 model year and continue with the C8 Corvette Z06 shortly thereafter. Cadillac will join the fray on its own schedule to run with BMW Ms, Mercedes-AMGs, Porsche Panameras, and the like. You heard it here first.
