525 RLB

High-revving, high-strength racing engine in long block form For racers who want to complete their engine with their own induction system, Chevrolet Performance now offers the 525 RLB (P/N 19435005) — a sealed long-block assembly based on the high-revving, high-strength CT525 racing crate engine and developed for universal racing sanctioning bodies. The 525 RLB crate engine is assembled with strong forged pistons and heavyduty connecting rod bolts designed to support its performance capability and help enhance its durability. With its deep-breathing LS3 rectangular-port cylinder heads, it is 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 a coil-on-plug ignition and an SFI-certified balancer, 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 available from Chevrolet Performance. See page 149 for more details and the additional parts needed to make this specialized long-block assembly the complete engine that will help drive you to the checkered flag
