I had a strange idea of reading the instructions, so I found the Holley model 4106 #0-8007 instructions on Summit Racing. Which had a diagram for the 390cfm carb:
Looks like the carb already includes ports for the PCV and HEI vacuum advance hoses right on the carb. There's another port labeled full manifold vacuum, and recommends it for the Thermac air cleaner, but I'm not sure if it should also be used for the Evap canister? I don't see a line to hook the fuel bowls to the Evap canister tho? Or any indication that the 390cfm carb has the purge valve built in for the Evap system?
