You need to call QuickFuel (now Holley, again). There are a lot of approved carb numbers that aren't on any published NHRA lists. You are probably looking at the 585 vs to replace a Holley for SBF. On the Holley/QF catalogue page is the following:

"585 CFM QuickSel'" vacuum secondary for Stock and Super Stock; replacement for Holley" 1.250" primary, 1.313" secondary venturi 1 9/16" throttle bore Replaces list numbers: 2818, 3043, 3139, 3140, 3245, 3367, 3419, 3420, 3530,3557, 3793,3795,3796,3806,3810,3811, 3814,3815, 3807,3836,3837,3838,3839,4088"

Hope this helps. I went through the same thing.
