Is it possible to make a Holley 4106 Vac. secondary carb, to a dual feed?
In a sense, removing the transfer tube?

I am building a dual quad, and I am thinking that the transfer tube, will not supply adequate fuel.

I went with these carbs, as I don't have to turn them sideway's. And I got a great deal too....

i'm sure you could with some drilling and tapping... but i've never seen anyone do it... and most likely since the carb isn't setup for it, it'd prolly cause a lot of problems... wait for one of the carb wizards to reply tho

I'm setting up 2 4160 (450 CFM) mech. sec. Holley's on a tube tunnel ram, feeding a 540 cu.in. Cadillac. I had the same fuel volume concerns as you. I scrounged up a pair of used float bowels, and as soon as I can find the time, I'm gonna drill and tap the transfer tube holes for 1/8 inch NPT, and run fuel hose and a "T" fitting for a second feed point to the carb, between the front and rear bowels. I think this will work, but I haven't measured the boss sizes yet. It might over power the floats or upset the metering, I just don't know enough about holley's to know, so I'm just gonna try it. Any of you Holley guru's want to jump in here?????? tks Paul

Here's a pic of what I'm going to use.

Holy Bejesus......Look at that thing.


Post a pic, if and when it gets done.....I will let you do all the hard work first....LOL
