Over the years I have ran everything from WCFB to 780 Holleys. Currently my chevelle (355/350th 3.08) has a Qjet and I have ran it two years without any problems or adjustments. tiny primaries so mileage is pretty good. Before that I had a 500cfm Holley @bbl on it. Not as good of mileage as the Qjet because the bores are larger. Got rid of it when the idle circuit starting acting up and I could not get it to run right. Before that I had a Edlebrock 600cfm Performer, but the idle circuit in it went fubar too. Not as good of mileage as the Qjet. On other SBCs I have had Holley carbs, but always seemed to be fiddling with them. Ok for race applications where it is full throttle. Around here you can get Qjets off of running engines for less than $50 when guys upgrade. Get the early ones before they added all the electronics. IF you want to speed the cash I have heard good things about the Edlebrock FI systems but have no personal experience.
