ATK High Performance Chevy LQ4 6.0L 505 HP Long Block Crate Engines

ATK High Performance Chevy LQ4 6.0L 505 hp long block crate engines are designed to be a performance upgrade for LS-based vehicles or perfect for a 2001-07 Chevy Truck LQ4 or LS swap in a hot rod. Expect big mid- to upper-end power, with a noticeable idle. (For optimal performance, you'll need headers, chassis dyno tune, and 36 lb. injectors. Engine specifications: * Horsepower: 505 * Torque: 480 * Block: OE LQ4/6.0L Iron * Bore/Stroke: Up to 4.040 in. x 3.622 in. * Displacement (cu.in.): Up to 371 * Crankshaft: OE GM 24-tooth reluctor wheel * Rods: OE powder metal or stock GM * Pistons: Hypereutectic 10:1 compression * Rings: Moly * Camshaft: Hydraulic roller * Cam specs: Custom performance grind * Timing chain: OE single roller * Cylinder heads: OE cathedral port aluminum 71cc/210cc 2.00/1.55 * Rocker arms: 1.7 ratio * Oil pump: Melling STD volume * Engine info: -- Oil: Conventional / Non-Synthetic 10W30 -- Oil Filter: Wix or K&N -- Timing: Set to factory specifications via PCM module -- Spark Plug Gap: .040 in. -- Firing Order: 18726543 -- Octane: 91+ -- Stall Converter: 1800+ -- Exhaust: 1 5/8 + Headers (Per application – Larger diameter will make more power) * NOTES: This engine replaces the 2001-07 Chevy 6.0L LQ4 engine. ECM MUST BE TUNED; not doing so can damage the engine. A PCV valve must be run. You must also run an air-oil separator system such as the Moroso 85487 to capture the excess crankcase vapors LS engines are known for. If you are not running a MAP sensor, the MAP timing option in the timing control box must be zeroed out all the way across. Failure to do so will allow the controller to add timing which can lead to detonation. You must also run some sort of a steam line kit that dumps to your water pump, radiator or radiator hose; ATK recommends a 4-corner setup like the Trick Flow TFS-306SB601. This allows air pockets/hot spots to escape the heads and can also be used to purge out trapped air when filling the radiator for the first time.
