The recently-announced Chevrolet Performance ZZ632 Crate Engine is officially the biggest and baddest. There has never been a Chevy crate engine more potent than this one. But that got us thinking about other GM motors as the automaker has a history of building some monsters. Back in 2016, GMPartsCenter.net made an infographic that highlights the 10 biggest GM engines in history. The graphic ranks the “big ten” engines in cubic inches, horsepower, and torque with a pre-war Cadillac V16 and Chevy 572 crate engine serving as the bookends.
“We thought it would be fun to republish this infographic on the biggest GM engines again,” said Carl Anthony, Managing Editor here at Automoblog. “GM’s big displacement production dates back to the 1930s when Cadillacs featured V12 and V16 engines, which is where this infographic starts.”
“In 1938, the 7.1-liter V16 Cadillac Series 90 engine was state of the art, producing 185 horsepower. Three decades later, the Olds 455 was producing 400 horsepower with eight fewer cylinders,” explained Matt Mylan, GMPartsCenter.net Director. “Three more decades and Chevy’s 572 crate motor can produce 720 horsepower, nearly twice the power of the Olds 455.”
