Use a small [ 800 cfm ] TQ carb. To resist the temptation to use the secondaries, disconnect the link connecting the pri to sec. The extra booster ring in the TQ primaries provides exceptional fuel metering & atomisation, a must for good economy.
Not a bad idea at all. Never once in my mopar mind have I thought about using a Thermoquad for economy but I can see how the small primaries would benefit very well. The big secondaries would help for passing situations as well
