About the LS 5.3 500HP Engine

The 5.3L LS is the most widely produced engine in the LS family, found in millions of GM trucks and SUVs. Its iron or aluminum block is strong, and with upgraded heads, a performance camshaft and supporting parts it can make far more power than stock. Reaching 500 horsepower from a 5.3L shows how much potential this platform has when it is built properly.

Because it shares mounting and accessory dimensions with other LS engines, the LS 5.3 500HP engine is easy to fit into trucks, muscle cars and import chassis that already have LS swap kits.

Before You Buy

• Ask for the build sheet, including cam specs, heads and valve springs.
• Plan a fuel system and tune to support 500HP.
• Confirm the oil pan and accessory drive for your chassis.

Break-In Tips

Prime the oil system, follow the builder’s break-in procedure and change the oil after the first few hundred kilometres. Verify the tune on a dynamometer if possible.
