Installed the 1″ aluminum spacer on top of a Holley Sniper EFI in order to gain clearance for the throttle linkage, which allowed me to use the factory cowl induction air cleaner on my SBC 327 motor. You need to remove the air cleaner middle spacer ring from between the air cleaner base and seal reatainer in order to maintain clearance to close the hood and seal to the bottom of it.
