I know a lot of parts can be interchanged between Demon's and Holley's. I'm using Holley jets and gaskets on my Demon now. But how about things like metering blocks? My Road Demon Jr. uses a metering block instead of jets for the secondaries. The same as the Holley that came off the car. Since the Demon primary jets are WAY big out of the box, I'm guessing the secondaries are the same way. Will the Holley metering block work on the Demon? I've never seen a listing for different size BG plates, and I doubt they would be cheep. Anyone ever tried this?
