Holley LS Swap Systems Take Out All the Guesswork
Holley carries the most comprehensive LS swap systems on the market today. Our swap kits are compatible with the popular 200-4R, TH400, 4L60, 70, 80, and 85 automatic transmissions, and if you want to bang some gears, you can choose one for the T-56 or T-56 Magnum manual transmissions. Complete LS swap kits are available for popular GM A, F, G, and X bodies as well as the C-10, and S-10 truck platforms. We even carry kits to swap your LS powerplant into such non-GM vehicles as Fox Body Mustangs and Nissan 240SXs, with more coming all the time.
Holley takes all the guesswork out of it for you. We test and develop LS engine swap kits to work with both current and future Holley products, ensuring that whether you're installing Holley accessory drives, Hooker engine mounts and transmission cross-members, or BlackHeart headers and exhaust systems, they all work without issue. Don't forget about our other great swap parts – Frostbite radiators, Sniper EFI conversion fuel tanks, and the complete line Holley EFI fuel systems. And once that LS engine is installed, we can help you dress it up with a huge selection of valve covers, air cleaners, valley covers, and more from brands like Holley, Sniper, and Mr. Gasket. And just because we're on top, it doesn't mean we're going to stop. We use constant feedback from engine builders, racers, and LS engine enthusiasts just like you to help us design and develop new LS parts all the time, so be sure and check holley.com for all the latest LS engine accessories and swap parts available for your ride.
