Hi,

I'm using the Holley 4150 shown in the picture below.
I need to connect the following:

A- Electric choke vacuum line (this is 4 in the picture below) Which port should the other end of this vac line go to?
B- HEI vacuum advance line
C- PCV valve (I assume it goes to 5 in the picture which is in back of the carb, correct?)
D- Governor vacuum connection for Powerglide trans

Which carb vacuum fitting should each one connect to and which ones should I plug?

1- cap off
3 - distributor, Tee into your vac modulator line
This will give vac advance at idle which, in turn, will let you run the carb leaner at idle and keep your throttle blades adjusted where they will stay out of the transfer slot circuit.
