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 Viking Auto Repair Electric & Air at 904-731-5065 to get started with your LS engine swap.

At Viking Auto Repair Electric & Air, we specialize in turnkey engines such as the LS3, LS7, LQ9 and LSX series. The mechanics at Viking Auto Repair Electric & Air 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 Viking Auto Repair Electric & Air 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 Viking Auto Repair Electric & Air 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 Viking Auto Repair Electric & Air 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

What People Say About Us

  • Best Service!

    My son is a student in Jacksonville. He needed an alternator for his car. While he was in class the staff at Viking worked with me over the phone to ensure that his car was ready to go as soon as possible. I felt assured that I was being given the best service at a very reasonable price. If the need arises again I will make sure to go to Viking for service.

    Harry and Steve are great. One shop told me I needed a new condenser and they found it was just a pressure switch. Saved me $350! Good people.

  • reviewicon

    Very friendly and helpful people here. Rebuilt an alternator for 1993 Grand Marquis for me 15 years for the best price. Today I called for another rebuild though they couldn't help me due to the limited supply of parts for my Mazda, I'm still a happy customer, thanks for help!

  • reviewicon

    Fast service. Did not try to fix anything that wasn't broken. Told me what the issue was and fixed it. Pricing is good. Will return if services are needed again.

    Harry (owner) is a very honest, reasonable and transparent owner- something you don't find with most local and nationwide shops. I highly recommend him!!

    When the alternator on my Volvo needed to be replaced, Harry gave me the best price out of all of the shops I received quotes from (five shops total, the highest quote was over $300 more than I was charged here). Very happy.

    After exhausting all other options to find a another alternator for my home generator I went and saw Harry at Viking. Within hours he had a replacement and later that day it was installed. Before going to Viking I had given up hope. These guys came through and made the impossible a reality. Highly recommend them!!

    Mike and Harry are awesome! Fuse kept blowing and no rear lights would work. Mike figured out the problem quickly and got the parts ordered ASAP, all for a fair price!

  • reviewicon

    Super awesome shop. My first visit but certainly won't be my last. Did great work and did it quickly. I highly recommend Viking.

  • reviewicon

    Left my car late on Sunday night because the dashboard warning lights had gone crazy and worst of all my power steering was not working. Viking called the next morning with the diagnosis, turns out it was the alternator, and the estimate. Repair was completed in a timely manner and I have my vehicle back. Thank you gentlemen for the great work!

  • reviewicon

    I picked up my car today. Very clear explanations from Staff, regarding my repairs. The price was also reasonable for my oil pan assembly install. Mike, also informed me of additional detail regarding my vehicle... I will recommend anyone to seek Viking, before seeking Dealerships!
