The Chevrolet Performance LS376\/525 is our most powerful naturally aspirated production-based crate engine, purpose-built for no-compromise performance.\u003cbr\u003e\u003cbr\u003eAt its core sits an aggressive ASA camshaft—the same hydraulic roller developed for circle-track racing—delivering .525-inch lift and 226 degrees intake \/ 236 degrees exhaust duration at .050-inch. That tight 110-degree lobe separation angle means excellent throttle response and exceptional high-rpm breathing. Pair it with higher-rate valve springs, and you get 525 hp at 6,200 rpm and 486 ft.-lbs. torque at 5,200 rpm.\u003cbr\u003e\u003cbr\u003eThe foundation is bulletproof: cast-aluminum block with 6-bolt cross-bolted main caps, nodular iron crankshaft, powdered metal connecting rods, and hypereutectic pistons. Aluminum L92-style cylinder heads with 68cc chambers flow premium air into a 10.7:1 compression ratio that demands 92-octane fuel. Cast roller rocker arms on a 1.7:1 ratio complete the valvetrain.\u003cbr\u003e\u003cbr\u003eMaximum recommended rpm hits 6,600. The engine ships as a complete long block with EFI intake, fuel rails and injectors, ignition coils, plug wires, spark plugs, oil pump and pan, harmonic balancer, timing cover, and water pump. Internally balanced with 58X reluctor wheel. Ready to bolt into your Camaro, Chevelle, or any resto-mod hungry for serious power.\u003c\/p\u003e\n\u003cp\u003eSpecifications:\u003cbr\u003ePower: 525 HP @ 6200 RPM, 486 ft. lbs. of torque @ 5,200 RPM\u003cbr\u003eDisplacement: 376 CID, 6.2L\u003cbr\u003eBore x Stroke: 4.060” x 3.620”\u003cbr\u003eCompression Ratio: 10.7:1\u003cbr\u003eRecommended Fuel: 92 Octane\u003cbr\u003eBlock: Cast Aluminum with 6 bolt cross bolted main caps\u003cbr\u003eCrankshaft: Nodular Iron\u003cbr\u003eConnecting Rods: Powdered Metal Steel\u003cbr\u003ePistons: Hypereutectic Aluminum\u003cbr\u003eCamshaft: Steel Hydraulic Roller Tappet\u003cbr\u003eCam Lift: .525” Intake \/ .525” exhaust\u003cbr\u003eCam Duration @ .050”: 226 deg.
