dual quad low profile?

Well, I definitely know the Holleys.....and done enough work on them. The first one I had was a 600 SP that leaked fuel like a lawn sprinkler on a golf course from the throttle shaft bushings. I'd go out and thrash my Duster on a good run and find little puddles on the intake......Yikes! :wack:
After I changed the teflon bushings it was better, but not perfect, as the base casting was worn from some twit running it with no bushings. (No, not me; the guy I bought it from used!) I put a secondary metering block on it and finally got the secondaries tuned, after going through four or five springs and about a dozen jets. Just about then a guy offered me the 650 double pumper and I had to start all over again (though, for me it was a much easier carb to tune). So, I figure I've paid my dues with the Holley Blues. But again I have no beef with the Carters except for the choke thing. Also with the 2X4 setup Holleys have to be mounted sideways unless you're using the shorty SP's with a secondary metering plate. The Offy manifold won't even take Holleys sideways. Oh well, as I said, I've got time to think on this one.
