7.0 | 7.4L Engine

7.0 | 7.4L Engine

One of the most legendary engines in muscle car history is the Chevy 454 Big-Block. With the LSX Bowtie block, GM Performance Parts engineers were able to build a 21st century 454 with the latest technology – and it requires no more space under the hood than a production LS engine. It’s perfect as the power plant for a late-model Camaro drag car or a high-tech retro-fit for a ’70 Chevelle pro-touring machine.

  • After only a few short years, the LS7 7.0L engine of the Corvette Z06 is a legend in its own time. Sure, it’s got more than 500 naturally aspirated horsepower and 470 lb-ft of torque, but the exceptional high-rpm performance and low-end grunt gives this 427-cubic-in combination the great tractability for which LS engines are known and the pulling power expected of a Big-Block with its historic displacement.

The LS7 features a unique big-bore cylinder block that is anchored with a forged crankshaft, featherweight titanium connecting rods and durable, friction-coated pistons. But it’s the airflow capability of the LS7’s cavernous, CNC-ported heads that enables its tremendous power. Large-volume, straight-passage intake runners channel air directly through 2.20-inch titanium intake valves. The mixture is burned in large, 70cc combustion chambers and what’s left exits through 1.61-inch sodium-filled exhaust valves. And did we forget to mention the dry sump oiling system? This is a serious engine for serious enthusiasts.

GM Performance Parts’ LS7 7.0L crate engine package includes a production style engine with the dry sump oil pan. You’ll need to supply the external oil supply and oil lines to the engine, but the rest of the assembly is fully dressed, including the manifold assembly with injectors and electronically controlled throttle body, and log-style exhaust manifolds.

  • Chevrolet Performance LSX 454R crate engines are designed for the unique, high-rpm demands of drag racing. These 13.1:1 compression, naturally-aspirated, big-inch LS engines are officially rated at 776 hp at 7,000 rpm with 649 lbs.-ft. of torque at 5,100 rpm; and Chevrolet knows there is room for more. But more than power, the 454R engines are built for durability--the cast iron LSX Bowtie cylinder blocks are filled with all-forged rotating assemblies

They breathe through Chevy's LSX DR 11-degree, six-bolt aluminum cylinder heads that feature raised ports with 313cc intake runners to provide tremendous airflow. Chevy complements them with an exclusive, high-rise open-plenum intake manifold and a Dominator-type carburetor to complete the assembly. Chevrolet Performance LSX 454R crate engines are the ones you can depend on round after round, season after season, to deliver success at the track.
