A new, higher-lift camshaft helps it produce 570 horsepower and 540 lb.-ft. of torque—increases of 65 hp and 70 lb.-ft. over the production-based LS7 crate engine. Additionally, a new wet-sump oiling system facilitates easier and less costly installation, because the supporting components for the production-based LS7’s dry-sump system are not required.\u003cbr\u003e\nProduct highlights:\u003cbr\u003e\n• Based on the production LS7 crate engine\u003cbr\u003e\n• Unique high-lift hydraulic roller camshaft with.591-in. intake\/ .590-in. exhaust lift\u003cbr\u003e\n• Unique high-rate valve springs\u003cbr\u003e\n• F-body wet-sump oil pan and specific wet-sump oil pump\u003cbr\u003e\n• Low-profile LS7 EFI intake manifold with fuel rails, injectors and throttle body installed\u003cbr\u003e\n• CNC-ported cylinder heads featuring 2.2-inch titanium intake valves\u003cbr\u003e\n• Comes assembled with 14-inch Camaro Z\/28 168-tooth manual transmission flywheel\u003cbr\u003e\n• Use with LS427 Engine Controller P\/N 19420000 (sold separately)\u003cbr\u003e\n• Not intended for marine applications\u003cbr\u003e\nTECH SPECS\u003cbr\u003e\nPart Number: 19420191\u003cbr\u003e\nEngine Type: LS-Series Small-Block V-8\u003cbr\u003e\nDisplacement (cu in): 427 (7.0L)\u003cbr\u003e\nBore x Stroke (in): 4.125 x 4.000 (101.6 x 92 mm)\u003cbr\u003e\nBlock (P\/N 12602689): Cast aluminum block with 6-bolt, cross-bolted main caps\u003cbr\u003e\nCrankshaft (P\/N 12611649): Forged steel\u003cbr\u003e\nConnecting Rods (P\/N 12661677): Forged titanium\u003cbr\u003e\nPistons: Hypereutectic aluminum\u003cbr\u003e\nCamshaft Type (P\/N 19419859): Hydraulic roller\u003cbr\u003e\nValve Lift (in): .591 intake\/.590 exhaust\u003cbr\u003e\nCamshaft Duration (@.050 in): 227º intake \/ 242º exhaust\u003cbr\u003e\nCamshaft Lobe Separation Angle: 116º\u003cbr\u003e\nCylinder Heads: CNC-ported LS7-style ports with 70cc combustion chambers\u003cbr\u003e\nValve Size (in): 2.200 titanium intake, 1.610 sodium filled exhaust\u003cbr\u003e\nCompression Ratio: 11.0:1\u003cbr\u003e\nRocker Arms: Investment-cast, roller bearing trunnion\u003cbr\u003e\nRocker Arm Ratio: 1.8:1 (offset intake)\u003cbr\u003e\nRecommended Fuel: Premium pump\u003cbr\u003e\nMaximum Recommended RPM: 7,000 rpm\u003cbr\u003e\nBalanced: Internal\u003cbr\u003e\nNOTE: LS427\/570 engine will include F-body wet-sump oil pan. \u003cbr\u003e\nChevrolet Performance recommends 15W-50 MOBIL 1 engine oil for the LS427\/570 Crate Engine\u003c\/p\u003e","brand":"My Store","offers":[{"title":"Default Title","offer_id":67611450835260,"sku":"19421004","price":15999.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/specbuiltls.com\/products\/ls7-570hp-wet-sump-crate-engine-7-0l-427-19421004","provider":"My Store","version":"1.0","type":"link"}
