Hi , been reading and learning on this forum and the racing fuel systems forum for the last year and a half . This is my first post , a buddy of mine runs a late model pro stock with a sealed crate engine and it has the 650 HP Holley carb on it .After learnig about the too much emulsion and too big of air bleed problem with the newer carbs I am doing the mods to the blocks to fix them . Looking for advice on what to start with for a main air bleed . I mapped it out , metering blocks have 3 hole e bleeds 1 .027 2 .031 3 .035 it has a .037 IFR up high .050 PVCRS #68 mains front and rear , IAB .068 MAB .041 . I relocated the IFRs to the low position and dropped it to a .032 blocked the #3 e bleed and drop 1 And 2 to .026 . Would love to hear your thoughts thanks .

I'm sorry I missed this post. I changed things in order to be notified to email with new threads/posts. MAB's of 0.025"-0.028" are common, and better with your good mods so far than the ridiculous 0.041"...

Thanks , going to try .028 bleeds , got to wait for the tracks to open to get some testing done . Already did the circle track advance curve to the MSD and it made a huge difference off the corners .Hope the carb mods make it more consistent, I have a LM2 that I will put on it to check it out .
