America\'s Oldest Speed Shop® Lincoln, NE GM Performance 19244098 LS7 7.0L Engine, 427 CID Sku # 35519244098 Mfr. Part # 19244098 Condition New Brand Chevrolet Performance Parts Sold Each Details Info
When people look back at high-performance engines, the Camaro Z/28’s LS7 will be remembered as a benchmark in naturally aspirated power. When it is all said and done, it will be one of the most popular LS crate engines ever offered, with 505 horsepower and 470 lb-ft of torque.
Within its classic 427-cu-in displacement, engineers extracted Big-Block grunt from its high-revving Small-Block package. It features a unique, big-bore cylinder block that is anchored with a forged crankshaft, featherweight titanium connecting rods, and friction-coated pistons. But it’s the airflow capability of the 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.
Chevrolet Performance\'s 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.
