I just rebuild an old Holley I had, a factory replacement. There are some ports on the carb that are not on the Holley 3310 that I am using now. It's a 600 cfm list number 6909. I am running a 383 with the dual snorkel air cleaner and have the 3 nipple air breather on the valve cover. I think the nipple I have taped off goes to the top of the front bowl on the 600 cfm carb.? Does anyone have any factory pics. I have manual brakes so no booster. Does the pvc go to the back port on the carb? I use full manifold vacuum I know that goes to the base port. I will cap off the timed port. Thanks in advance. It's a 71 Road runner.
