On my 470 the QF 1050-AN (annular boosters) worked much better than the Holley 850 and 950 that I tried. The 950 was converted to annular boosters which improved it significantly, but the QF 1050 was still the best carb.

However, this is just dyno testing where we run the engine from 5000 to 7000. The carbs could behave differently on the street or the track. On the dyno we don't really have a way to test "driveability" issues.
