CRATE ENGINE 6.2L LS3 533HP
533 Horsepower, 477 ft. lbs. Torque
Part Number: GM19435005
Chevrolet Performance?s 525 RLB is based on the LS engine family and is like the 6.2L CT525 but sold as a sealed long block for universal racing sanctioning bodies.
The high-revving 525 RLB crate engine is assembled with strong forged pistons and heavy-duty connecting rod bolts designed to support its performance capability and enhance its durability. With its deep-breathing LS3 rectangular-port cylinder heads, it is a combination rated at 533 horsepower at 6,600 rpm and a strong 477 lb.-ft. of torque at 5,200 rpm, when used with a 4-barrel carburetor and intake manifold, per Chevrolet Performance testing.
The engine assembly comes with coil-near-plug ignition and an SFI-certified balancer, along with a 6-quart racing oil pan and more. All that?s needed to complete the assembly is an induction and ignition system ? and all those components are also available from Chevrolet Performance.
