GM LS3 6.2L 533 Horsepower CT525 Crate Engine (GM19432720)

Designed for racing classesrequiring more power than our proven CT350, and CT400 Gen I based racing engines, the all-new CT525 delivers the goods! It is an ideal engine for Super Late-Model-type cars.

Based on the latest production version of the now-famous Gen IV LS family of GM small-blocks thatpower the C6 Corvette, the CT525 is destined to set a newstandard for affordable power.Aluminium block and heads, hypereutectic aluminum pistons, nodular iron crank and hydraulic roller tappet camshaft churn out an impressive 533 horses in a bullet-proof race-proven package. The recent design changes that have produced thepower-building rectangular port cylinder head design, also create a torque-y, yet relatively high revving engine. The CT525 fills the "Need for Speed" at a surprisingly affordable price. The CT525 uses a conventional four-barrel carb,individual runner manifold, retaining the factory coil-near-plug ignition design.

Includes a 6 quart circle track oil pan that is designed to clear mostGM rear-steer chassis with stock engine location. Requires external oil filter and cooler which increases oilcapacity to approximately 8 quarts.
