These billet adapters place the Cadillac M122 Supercharger on LS1/LS2/LS6 and 4.8/5.3/6.0 cathedral port engines with the truck pulley spacing. No machining to your blower is necessary!!! It is possible to machine the blower snout shorter for other offsets. Machined with dovetail O-ring grooves makes for a painless reusable cylinder and manifold seal.
This is for the adapter plates and install hardware only!
