That makes it the most powerful naturally aspirated 6.2L street engine in our portfolio – and one that has an edge to it. You’ll notice it in the idle quality and you’ll feel it when the revs quickly climb.\u003cbr\u003e\nThe ASA camshaft is a hydraulic roller with .525-inch lift on both sides, along with 226 degrees duration on the intake side and 236 degrees on the exhaust side. Coupled with a tight, 110-degree lobe separation angle, it helps the engine deliver excellent throttle response and breathe exceptionally well at high rpm. And for durability, we complement the cam with higher-rate valve springs.\u003cbr\u003e\nYou’ll need tuning to make the most of the engine in a late-model GM vehicle. If you plan to use the engine in a vintage car, you’ll need controller kit P\/N 19354332, which includes the throttle pedal to match its electronically controlled throttle body.\u003cbr\u003e\nTECH SPECSPart Number: 19435104 - NEW F-BODY PAN \/ NO EXHAUST MANIFOLDS. REPLACES: 19434642, 19419866, 19370413, 19301360, 19369338Engine Type: LS-Series Gen IV Small-Block V-8Displacement (cu in): 376 cu in (6.2L)Bore x Stroke (in): 4.065 x 3.622 (103.25 x 92mm)Block (P\/N 12623967): Cast aluminum with 6-bolt, cross-bolted main capsCrankshaft (P\/N 12597569): Nodular ironConnecting Rods (P\/N 12607475): Powdered metalPistons (P\/N 19207287): Hypereutectic aluminumCamshaft Type (P\/N 88958770): Hydraulic rollerValve Lift (in): 0.525 intake \/ 0.525 exhaustCamshaft Duration (@0.050 in): 226° intake \/ 236° exhaustCylinder Heads (P\/N 12629063): Aluminum L92-style port; as cast with 68cc chambersValve Size (in): 2.165 intake \/ 1.590 exhaustCompression ratio: 10.7:1Rocker Arms (P\/N 12669995 int): Investment cast, roll trunnionRocker Arms (P\/N 12669993 exh): Investment cast, roll trunnionRocker Arm Ratio: 1.7:1Recommended Fuel: Premium pumpMaximum Recommended RPM: 6,600Reluctor Wheel: 58xBalanced: Internal\u003cbr\u003e\nINSTALLATION NOTES• Assembly does not include any electronics• Use LS376\/525 Engine Controller Kit for engine operation, P\/N 19354332• Includes LS1 F-Body wet sump oil pan• Does not include exhaust manifolds• Intended for pre-1976 street vehicles or any off-road vehicle• Not intended for marine applications• Front-End Accessory Drive Kits are available in several configurations.\u003cbr\u003e\nChevrolet Performance Crate Engines include a 24-month or 50,000-mile\/80,000-kilometer limited warranty.\u003c\/p\u003e","brand":"My Store","offers":[{"title":"Default Title","offer_id":67611449033020,"sku":"19435104","price":12197.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/specbuiltls.com\/products\/ls3-525-533hp-crate-engine-6-2l-19435104","provider":"My Store","version":"1.0","type":"link"}
