Chevy Performance Reveals 10.3-Liter Crate V8 With 1,000 HP

On Wednesday, Chevrolet Performance announced the ZZ632/1000 — a naturally aspirated 632-cubic-inch (10,348 cc) V8 producing 1,004 horsepower and 876 lb-ft of torque on pump gasoline.

While 100 hp per liter may not be an engineering marvel today, delivering a crate motor that’s sized to embarrass every other powertrain installed into a production vehicle is an achievement in itself. This 10.3-liter behemoth makes the 8.4-liter V10 installed in Dodge’s Viper (rest in peace) look like it’s supposed to be fitted to a riding lawnmower. Of course, it’s also huge in comparison to literally every powertrain we’ve seen on a project car that didn’t source its parts from vintage aircraft.

I'm not complaining, to be clear, since I could've popped Peacock on and yet I chose to watch something else."Being you sounds like a real chore. 😉
