CT525 Sealed 6.2L LS Circle Track Crate Engine, Dyno Tested

A sealed 6.2-liter LS circle track crate engine rated at 533 horsepower and 477 ft-lbs of torque, built on an LS3-based cast-aluminum block for Super Late Model and Modified competition. What's inside This long block pairs a 376 cubic inch displacement (4.060 x 3.620-inch bore and stroke) with forged aluminum pistons, a nodular iron crankshaft, powdered metal rods, and a hydraulic roller tappet camshaft running a 525-thousandths lift figure and a duration profile of 226 degrees intake, 236 degrees exhaust. The LS3-style rectangular-port aluminum cylinder heads use 68cc combustion chambers with 2.165-inch intake and 1.59-inch exhaust valves, topped by a single-plane aluminum intake manifold, and the block itself uses six-bolt, cross-bolted main caps for strength at high rpm, with a 6,700 rpm maximum. What's included and what you'll need to add Valve covers, cylinder heads, oil pan, timing cover, harmonic balancer, and flexplate are installed, along with spark plugs and wires, but the carburetor, starter, fuel system, exhaust, and front accessory drive are not included, and a distributor and water pump are not fitted either, since the build is intended to run with a buyer-supplied ignition and cooling setup, plus an external oil filter and cooler for roughly 8 quarts of capacity. This engine is built and sealed for racing use rather than street driving, and racing engines like this one are sold without a warranty. Common questions Is a carburetor included? No, a carburetor is not included. Can this go in a street car? No, it is built and sealed for racing use only.
