RPM airgap with carb spacer?

Spread bores are EXCELLENT carbs for street/strip cars. Super responsive with those small primaries and huge secondaries when needed. The TQ is my favorite spread bore carb. Holley makes a good one. Quadra jet is ok but I don't like them as well as the TQ. The TQ's are plentyful and cheap enough. You can pick one up at swap meets for $25. bucks, get a couple for spare parts. You can run a TQ on a std. holley (4150/4160) flange with a spread bore open spacer/adapter. I ran one of those for years with NO issues. And put me down for the 8 3/4 ..yes, you WILL need that.
