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 Allied Auto Stores at 510-656-6233 to get started with your LS engine swap.

At Allied Auto Stores, we specialize in turnkey engines such as the LS3, LS7, LQ9 and LSX series. The mechanics at Allied Auto Stores 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 Allied Auto Stores 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 Allied Auto Stores 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 Allied Auto Stores 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

    Friendly staff helped me pick the correct parts for my car very quickly. Was in and out of there in a few mins.

    Great knowledge, helpful, good prices, worth the trip. I appreciate the level of professionalism. They are helpful with just the right tone, don't try to oversell me or treat me as brainless. I am given the appropriate prices and guidance, and I am very comfortable with their store, quality and recommendations. I drive past MANY chain options to get here, because they know what they are talking about, and they treat me right. It's worth driving to get to!!

    These guys definitely know their stuff. They were able to identify the heater control valve I needed for my Ranger over the phone and had it ready to go as soon as I got there. They even went the extra mile and had two different price levels ready for me and thoroughly explained the difference while allowing me to make my own decision. Definitely wont be going anywhere else from now on.
