SEMA 2014: Chevy Performance Highlights the Gen V LT1 Crate Engine

Over the past few years, Chevrolet Performance (nee General Motors Performance Parts) has found a lot of market success with their LS crate engine program. They’ve offered everything from mild 5.3 truck engines all the way up through the 638 horsepower LS9 from the C6 Corvette ZR1, so it’s not surprising that they’ve almost immediately made the new Gen V LT1 engine that powers the new Corvette Stingray available as a crate engine, too.

LT1 Specifications

Bore x Stroke: 4.065 x 3.622 (103.25 x 92mm)

Crankshaft: Forged Steel

Valve Lift: 0.561 intake, 0.531 exhaust

Camshaft Duration: 242 degrees intake, 244 exhaust

Rated at 460 horsepower, the LT1 is available in both wet sump (PN 19328728, MSRP $11,000.00, $8,898.88 at Pace Performance) and dry sump (PN 19329997, MSRP $11,250.00, $9,189.88 at Pace Performance) versions.

The engine electronics (PN 19303137, $1,898.88 at Pace Performance) are set up to properly control the variable valve timing system, though the crate engine package doesn’t implement the Corvette’s Active Fuel Management cylinder deactivation function.

In addition to bellhousings to mate the LT1 to the manual gearbox of your choice, Chevy Performance will also be rolling out an electronically-controlled four-speed automatic specifically set up for this crate engine (PN 19329645, $2,198.88 at Pace Performance.)

While we were visiting with Chevy Performance, we also got a look at the 2015 COPO – once again, just 69 cars will be made for this model year, and with this being the last hurrah for the 5th gen Camaro, we expect these cars to be hot commodities among collectors. That’s not to say they won’t see the racetrack duty they were built for, though; Chevy has done a pretty good job of vetting potential buyers to keep speculation at a minimum.
