Its possible a bearing might have seized, you did plumb in the pressurized oil lines to the blower, and the return oil lines back to the crankcase? gotta have them or it won't go far.
Anyone have the blower apart before? could be rotor lockup, they have to be timed (clearanced) or they will jam and do damage.
As far as aftermarket intakes for the 22r specifically made for the Holley carb I don't know of any, but they do have adapters available to bolt the Holley to the stock intake.
