Is it one of the computer controlled 301 carburetors or a standard unit?....Cliff

If it is a turbo carburetor, there will NOT be hole in the throttle body to supply vacuum to the power piston.  The vacuum is routed in from the front of the throttle body between the mixture screws.  It should go thru a device in line to keep from pressurizing the PP under boost.....Cliff
