Tunnel ram carb tuning

I have jetted down from 66s to 60s to 57s with no change. I am definately running on the transition slot . Idle mix is 3/4 of a turn out. 15 to 1. 1850s so no replacement bleeds. However, quick fuel blocks with 3 #28 emulsion jets, 33 idle jet and like a fat 53 pvcr jet. I have co sidereal pulling them all apart again and drilling for replacement bleeds on the main body and putting in a .071 restriction in the transfer slot passage. Most people have said dont do that work with the air bleeds. I have given up and purchased the 2 tunnel ram carbs. This is strictly a street car. I may do these modifications over the winter. I also have a set of 660s which I may throw on IF I do go to the track,but that is unlikely. Valiant goes to the track. I will let you all know how the twin vac secondary quick fuel carbs treat Mr on the street. Should be here any day now.
