It features a compact, efficient 1.7L Eaton R1740 TVS supercharger, which spins at up to 20,000 rpm. That’s enough to generate more than 9 pounds of boost and help produce 650 horsepower and 650 lb.-ft. of torque.\u003c\/p\u003e\n\u003cp\u003eThe LT4 is based on the same Gen V Small-Block architecture as the LT1 engine, with several unique features designed to support its higher output and the greater cylinder pressures created by forced induction. They include Rotocast A356T6 aluminum cylinder heads, which are stronger and handle heat better than conventional castings, lightweight titanium intake valves and stronger forged aluminum pistons.\u003c\/p\u003e\n\u003ch2\u003eChevrolet Performance LT4 Crate Engine Installation Notes\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eAssembly does not include any electronics\u003c\/li\u003e\n\u003cli\u003eSelect the right controller kit for your LT4 engine (see chart on page 81 of catalog)\u003c\/li\u003e\n\u003cli\u003eFront-End Accessory Drive system must be ordered separately (see page 72 of catalog)\u003c\/li\u003e\n\u003cli\u003eCan accommodate P\/N 19420210 Hydraulic Power Steering Kit (not included with Accessory Drive System, see page 73 of catalog)\u003c\/li\u003e\n\u003cli\u003eIncludes 8-bolt flexplate\u003c\/li\u003e\n\u003cli\u003eNot intended for marine applications\u003c\/li\u003e\n\u003cli\u003eCrankshaft has 8-bolt flywheel mounting pattern\u003c\/li\u003e\n\u003cli\u003eEngine includes direct injection and VVT\u003c\/li\u003e\n\u003cli\u003eChevrolet Performance control kits do not use the Active Fuel Management components on this crate engine\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eMobil1 is the recommended engine oil for all Chevrolet Performance Engines\u003c\/p\u003e\n\u003ch6\u003eChevrolet Performance Crate Engines include a 24-month or 50,000-mile\/80,000-kilometer limited warranty, whichever comes first.
