Chevrolet Pulls The Plug On Another High-Horsepower Crate Engine

At some point, most of you, like us, have thought about sticking a Chevrolet Performance LT5 crate engine in a project. Let’s face it; there’s nothing like the sound and power of a supercharged mill under the hood with a factory warranty to boot. But, unfortunately, this dream has come to an end for some as we’ve learned that Chevy has pulled the plug on this killer engine and will no longer be offering the powerplant known for pushing the 2019 Corvette ZR1.

The 6.2-liter LT5 is rated at 755 horsepower at 6,400 rpm and 715 lb-ft of torque at 3,600 rpm at only 14-pounds of boost thanks to its efficient four-lobe design supercharger. A 2.65-liter supercharger sits atop the LT5 and is 64-percent larger than the now legendary LT4 engine’s blower, making it a monster. The LT5 offered a host of goodies to support the supercharger including, 10:1 Forged aluminum pistons with polymer-coated skirts, forged steel crankshaft, and Rotocast A356T6 aluminum cylinder heads. Unlike other GM direct injection engines, the LT5 utilized both direct injection and a secondary injection system as well.

LT5 Tech Specs

  • 4.06 Bore x 3.63 Stroke 
  • 10:1 Compression Ratio
  • Forged steel crankshaft
  • Forged aluminum pistons with polymer-coated skirts
  •  Rotocast A356T6 aluminum cylinder heads 
  • 2.13-inch titanium intake valves and 1.590-inch sodium-filled exhaust valves
  • R2650 2.65-liter supercharger
  • 11-rib supercharger belt drive
  • 14 psi max boost
  • 95mm throttle body
  • Direct injection primary with secondary port injection 
  • 755 horsepower at 6,400 rpm
  • 715 lb-ft of torque at 3,600 rpm

While we hate to see GM pull the plug on this supercharged powerplant, it’s not much of a surprise due to the $19,995 MSRP price tag. It also makes us wonder if the company will be removing even more crate engine options in the future since it announced its plan to go all-electric by 2035. For that, we will have to wait and see.

To this day, the LT5 is the most powerful engine that Chevrolet has ever offered in a production vehicle, and naturally, it was one of Chevy’s most potent crate engines as well.  Photo Credit – The Block

If you are looking for an LT5 crate engine, we wish you the best of luck. Unfortunately, companies like Scoggin Dickey, Jegs, and Summit Racing, which would usually have these engines in stock or at least access to one, have already posted that it’s no longer available or discontinued. And while Chevrolet recommends contacting your closest dealer, that could be a very long shot. But who knows, maybe you’ll get lucky. And while this may be a bummer for some, the good news is Chevrolet Performance still offers several LS and LT crate engines to choose from.
