Default Carb Boosters Info
Hi all,
I would like to replace the Straight Boosters on my Holley 4150 dp into Down Leg Boosters.
Is someone able to explain to me the different specification numbers like for instance:

Down Leg 0.600
Down Leg 0.500 I.D.
Down Leg 0.120
Down Leg 0.135 oriffce
Down Leg 45R-1-11

Looking forward to your replies - Thanks!

Rico
