Our 1978-1988 GM G-body LS Swap Kits are engineering to provide a complete and comprehensive solution for swapping an LS engine into your ride. Unlike many of the other swap parts and kits on the market where the engine is placed as high as possible, the engine positioning achieved with our Kits provides your vehicle with a lower center of mass and optimized engine inclination/ U-joint working angles. As an additional benefit, transmission-to-tunnel clearances (especially those regarding GM 4L80/4L85 transmissions) are greatly improved.

All of our LS Engine Swap Kits are fully configurable in the cart. Simply add the kit of choice to the cart and there you can remove parts you may not want or need. You may also add additional parts to the cart such as valve covers, EFI kits, or anything else you may need for your project.
