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\n****NOTES FROM PTS:-The ASA camshaft was originally designed for racing in the late 90's. This cam has a bit of valve overlap, and will have some additional fuel smell compared to other cams. -The horsepower on this engine makes peak power near redline. There is not a lot to be gained over the 495hp crate, other than a more lopey idle, and peak power. -If you have an automatic, make sure to have a high stall speed to help prevent surging. \u003cbr\u003e\nTECH SPECSPart Number: 19432557Engine 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 12649190): Powdered metalPistons (P\/N 19207287): Hypereutectic aluminumCamshaft Type (P\/N 12623063): 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, roller trunnionRocker Arms (P\/N 12669993 exh): Investment-cast, roller trunnionRocker Arm Ratio: 1.7:1Recommended Fuel: Premium pumpMaximum Recommended rpm: 6,600Reluctor Wheel: 58x Balanced: Internal\u003cbr\u003e\nINSTALLATION NOTES• Assembly does not include any electronics, intake manifold, fuel system, ignition coils\/harnesses\/brackets\/wires, or spark plugs. • Includes Chevy F-Body wet sump oil pan (may need to be changed depending on application). • Intended for pre-1976 street vehicles or any off-road vehicle• Not intended for marine applications\u003cbr\u003e\nTo make your long block into more of a crate engine, visit our exclusive product here: LS3 Long Block Completion Kit for 430 495 525 Crate Engines – Pro Touring Store\u003c\/p\u003e","brand":"My Store","offers":[{"title":"Default Title","offer_id":67611471610172,"sku":"19435110-No LG - Res","price":8259.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/specbuiltls.com\/products\/ls3-525hp-long-block-crate-engine-6-2l-533-19435110-no-lift-gate-residential-address","provider":"My Store","version":"1.0","type":"link"}
