Not sure which adapter plates you need for your LS series engine swap?

Swapping a GM LS series engine into an older GM vehicle just got a whole lot easier with Swaptech's patent pending multi-position motor mount adapter plates. They allow you to install the engine in a standard, 1" forward, or 1" back position, allowing you to find the right mounting spot to help with many of the common clearance problems found with most LS engine swaps. Our beefy 3/8" thick steel plates are perfect for stock or high horsepower applications, and work with most stock replacement and aftermarket SBC and BBC motor mounts without requiring motor mount grinding. Silver finish.  Installation instructions and premium automotive grade hardware are included. Proudly made in the USA.

Fitment
Fits Gen III and Gen IV Small Block Chevrolet engines including : LS1, LS2, LS3, LS6, LS7,  and Truck/SUV applications (4.8L, 5.3L, 6.0L).
