Why Buy a Rebuilt LS3 Engine

The LS3 first appeared in the 2008 Corvette and later powered the Camaro SS and other GM performance cars. Its large-bore aluminum block and high-flowing heads make it one of the most popular platforms for swaps and builds. A rebuild restores worn components and gives the engine a known starting point, which is especially valuable when you are investing in a full swap.

At 525HP, this rebuilt LS3 engine delivers a big jump over stock while keeping good drivability for street use. It is a great choice for restomods, trucks and weekend track cars.

Before You Order

• Ask us for the build sheet, including cam, valve springs and parts used.
• Confirm the oil pan, accessory drive and intake height suit your vehicle.
• Plan for a tune that matches the camshaft and your transmission.

Break-In Tips

Prime the oil system before first start, follow the builder’s break-in procedure and change the oil and filter after the first few hundred kilometres. Check for leaks and retorque fittings where appropriate.
