Quadrajet Carb Talk and Tips / Large or small main air bleed?
« Last post by 68rs/ss on March 11, 2024, 06:41:59 PM »Just curious and looking to be educated some. I am wondering if there are any benefits to running either a small or large main air bleed carb on a performance build? I've done a few carbs that were all newer and were all LMAB. I realize the big bleed carbs use bigger jets and bigger primary rods while the smaller bleeds use smaller jets and rods. Is one better than the other for performance or tuning? I see in Cliff's book that there is a section showing how to change and add restrictions to the bigger bleeds, thus, using the smaller jet and rod combination after.
At the end of the day, would either work equally well or is there a benefit somewhere to using one or the other? Guessing the A/F would be similar if both were tuned to a same application, just a different way getting there?
Hope this is a dumb question.

Choke is not even close. I dont like the sandblasted finish and the phillip
head bowl screws either. Open hole in top. No telling whats been done inside.
At this point I would reccomend finding a better carb.
Dont mean to sound discouraging but....

and valve are harmless. Just dont wire it up.
