LS Engine Swap

LS Engine Swap

Don't wait one more day to feel the power of a new GM LS engine. Get the most out of your LS engine whether you prefer a street, off-road, supercharged or stroker assembly. Call the mechanics at Ruffing Automotive Services at 920-766-7889 to get started with your LS engine swap.

At Ruffing Automotive Services, we specialize in turnkey engines such as the LS3, LS7, LQ9 and LSX series. The mechanics at Ruffing Automotive Services will determine what adjustments need to be made to your vehicle to create the perfect fit and maintain original function. We will also recommend the correct frame and motor mounts for your specific car or truck.

LS Engine Swap Cost

GM makes a powerful and affordable engine. Making a LS engine swap convenient and affordable is our highest priority.

First, the mechanics at Ruffing Automotive Services will help you estimate the cost of your LS engine swap by considering the driving application and your style. LS3 series engine swaps are popular for street applications while the LS7 series is for trucks and off-roading applications. The LS3, released in 08 was the most powerful Corvette engine. The LS7 provides more horsepower for greater towing capacity than the LS3 and is the largest LS engine built by GM Performance.

Leave the Motor Mounts to Us

At Ruffing Automotive Services we know replacing the frame mounts and motor mount adapter plates are the foundation of a successful GM LS engine swap. Adapter plates bolt onto the engine block and secure it to the cross member. We have adjustable and stock location adapter plates available to create the perfect fit and maximum stability. Most car applications require the LS engine to be moved forward due to firewall clearance issues with the passenger side cylinder head. For GM LS and LSX engines we recommend 1" set back adapter plates to retain the factory transmission cross member and driveshaft distance.

For perfect fit and function Ruffing Automotive Services often recommends updating these important parts and systems.

  • Transmissions
  • Flex plates
  • Wiring and computer systems
  • Oil pans
  • Steam tubes
  • Gauges
  • Fuel systems
  • Exhaust systems
  • Carburetor conversions

    Jeff and Joe are easy to work with and I especially appreciate the use of a loaner vehicle for more complicated repairs. They give me an estimate and that's what I pay. They also have a fast turn around time.
