Look for the Holley Number on the side of the carbs . Should be a 4 digit # with a dash digit at the end. Example 8082-3 . look up the original specs start there. Good guess would be 88 Primary Jets and 35 ish Air Bleeds ( The ones closest to the bowl vent tube ) , with 3.5PV , 92 Secondarys with 35 ish Airbleeds and 3.5PV . Idle Air bleeds around 50 ish ( Outer Ones ) Idle Screws at 1 1/2 Turns . Make sure Primary and Secondary Throttle Plates are open Equally. If they are open much more than .010 , the idle circuit loses a lot of signal and they tend to go lean . You can check your Idle by Putting your fingers over all 4 Idle Air Bleeds , if it speeds up its lean , if it slows down its rich

I have 9.7 comp. and I run a dominator. I have 92 jets pri. 94 sec. 28 mab 70 iab. 4.5 power valves both sides. I think that set up would be safe to start with.
