Holley Carb help!

Hey folks!! So, I have a 350 sbc with a new Holley carb (I tried to attaché photo) I'm new here so I'll get a hang of it.

I'm looking for assistance with the lines for the carb (minus the fuel lines I have that done). I have a 4 barrel intake from a Rochester carb ... and a Holley carb with the adapter on it. I can't seem to find a diagram or resources to help figure out the hoses.

If anyone can help that would be great! This is all new to me, I built this vehicle myself and now it's time to start it. Just looking for some help as the local mechanic shops refused.

Thanks!

how many hoses are you trying to figure out ? there is only one or two that are vital to your engines performance .. the others are just worker bees sort of ..power break booster / PVC system / auto trans modulator / AC system if you have AC .. the performance one to be concerned with is the vacuum advance for the dizzy ...

Yeah basically that's what I'm trying to figure out haha. I'd like to find out which ones I actually need. I understand that gasline and the throttle and choke set up. But I was told to make sure the other lines were connected... which I have 0 clue what they are.

If you go to Holley's website you should be able to open a PDF manual on your model carb that will show you all that stuff.

On the passenger side of the carb on the metering block above the idle mixture screw the should be a port about 3/16th's or so and that is where the vacuum advance goes. At the base of the carb, from the picture I couldn't tell if it was in the front or the back, there should be a port about 1/2 or so and that is the pcv hook up. Any others I would just plug.

high port on pass side is timed spark advance. the 2 lower ones are manifold vacuum. the larger one is p/b or pcv .
