Run up front with the 400-horsepower CT400 crate engine (often referred to as the "604 crate") featuring Fast Burn heads from GM Performance Parts. Now, Speedway Motors Racing Engines is offering this 604 crate engine as a dyno-verified package that is ready to race! These IMCA-sealed 604 crate racing engines are based on the popular Fast Burn 385 street crate engine, but include a racing-only 8-quart circle track oil pan with dual kick-out design, along with a valve cover breather kit and special "kool nut" rocker arm design. The assembly also includes an open-plenum high-rise intake manifold and 1.5:1-ratio aluminum roller rockers. The 604 crate engine includes a bulletproof bottom end, anchored by a forged steel crankshaft and hypereutectic pistons. The 23-degree, Fast Burn aluminum heads enable tremendous power in the small-block V-8 because of a unique chamber design that quickly and completely burns all of the air/fuel mixture – giving you maximum power. With the CT400 racing engine under the hood of your Modified or Late Model, you'll put a "fast burn" on the competition.Dyno-verified horsepower and torquePiston rings are broken-in using a proprietary dyno programLash and timing are individually tunedEngine is ready to race, right out of the crateIMCA-sealed for equal competitionPopular in Modified and Late Model classes*400 HP @ 5500 RPM400 ft. lbs. of torque @ 4500 RPM4.00" x 3.48" bore x stroke9.6:1 compression ratio92 octane recommended fuel4-bolt main capsCam lift: .474" intake / .510" exhaustCam duration @ .050": 208° intake / 221° exhaust112° lobe separation1.5:1 ratio aluminum roller rocker arms2.00" Intake / 1.55" Exhaust valvesIncludes:Fully assembled long blockBlack steel valve covers w/ breathersOil pump, pick-up, 8 quart oil panEliminator Vortec intake manifoldSpark plugs8" harmonic balancerFront timing coverDyno sheet of your engineIMCA-issued bolts and is approved for use in IMCA
