Sherman adds a 1-inch spacer to the Performer RPM intake manifold, which he says is worth an additional 10 hp. As well as providing WOT power, since the 800-cfm AFB carburetor features primary metering rods that work off engine vacuum, they can meter fuel 12 percent leaner or richer, benefiting performance or economy-depending on how the engine is being used. Hood clearance with the RPM intake and spacer might be questionable on some Pontiacs, but not Orwin Middleton's '61 Catalina. View Related Article
