We have fitted a ls gm v8 in a GD Subaru. We haven’t tried a GC yet, but we think it might require some extra attention and finesse. This swap has two motor mount settings and moves the car’s frame down 1.5 inches. The front control arm mounts have a correction of one inch.
This kit comes with the motor mounts and a second set of spacers to further get the motor in the correct position depending how deep in the fire wall you want to go. front sump aluminum pan will be needed there is only 9 inches wide to clear the rack mounts to get the motor seated as far as possible
