Getting massive amount of power from a big block engine without the benefit of turbochargers or superchargers is a difficult path. Chevrolet Performance, however, took a route that copies from the past — increasing displacement. Its latest crate engine is not just the largest, but also the most powerful in its history – the ZZ632/1000.
Chevrolet Crate Engine: No Replacement To Displacement
Chevrolet Performance’s new crate engine is essentially a naturally aspirated big block V8 mill that – unlike Mopar’s latest Hellephant – does not require the help of superchargers to deliver 1,004 hp of max output at 6,600 rpm and 876 lb-ft of peak torque at 5,600 rpm.
The number 632 in its name refers to engine’s displacement in cubic inches, which is equivalent to roughly 10.32 liters. It features a Tall Deck 632 Bowtie Sportsman, cast iron block with RS-X Symmetrical Port CNC-machined aluminum high-flow cylinder heads and forged aluminum pistons as well as forged steel crankshaft and connecting rods.
New Crate Engine To Grace 2021 SEMA Show
Chevrolet Performance ensures that this massive crate engine can take some beating, since a prototype of the ZZ632/1000 managed to endure more than 200 simulated drag strip passes on a dynamometer. Chevrolet Performance will display the new ZZ632/1000 crate engine at the 2021 SEMA Show in Las Vegas, in Nov. 2–5. Deliveries will commence in early 2022.
