Thanks all.

Limiting the discussion (for me) to the Holley 750 DP, I see 7-8 iteratrions of 4779s on the Holley tech site that run from almost square jetted 75- 76s (with a small pump nozzle) to several in the 72-80 range. I'm looking specifically at the 82751 HP flavor which comes with 75-80s and 31/28 nozzles. Although initially it seems to run a richer primary circuit, it also has the milled/radiused body, choke housing removed, and adjustable air bleeds, which presumably would require fattening up on the jetting to achieve the same overall AF ratio, but I suspect something on the order of 72s or 73 on the primarys would put in (initially) in the ballpark. ???? Thanks all..
