    I would run 800-850they run great with smaller carbs but you do not realise what you are missing
    Now way would I go smaller than 750 considering they used a 850 TQ on a 340/360

    I have a 750cfm vacuum Holley. I do not see any reason to go smaller that that. The vacuum secondaries keep you out of trouble from "over-carburation", anyway.

    My Challenger has a very mild almost stock 440 (stock intake and exhaust manifolds, old real factory Magnum cam from a friend´s RT 383 Magnum, 1.6:1 roller rockers, AT and 3.23 gears). Easy to cruise on higways, good mileage (at least the same as what the magazines reported back in 1970 with similar 440/727/3.23 Challenger).
