Dave---are you sure about the vacuum line for the power brakes being o.k. for a pvc? I have been told that a power brake vacuum canister is a sealed unit with a check valve on the infeed line, so that effectively the vacuum line on the carb can only pull air there freely in the first minute or so after the engine starts, then once vacuum is created in the canister, the carb can't pull any more air there untill the brakes get applied, or the vacuum in the canister bleeds down while the car is setting with the engine shut off. If you use it for a pcv line, the carb will pull too much vacuum at that port all the time and cause the carb to behave like it had a vacuum leak at idle. I heard all this about 3 weeks ago when I first fired the engine in my roadster pickup. I had that brake vacuum port running to my pvc, and the engine wouldn't idle properly. When I plugged that line, the engine idle smoothed out a lot, which lead me to believe there may be truth to it.
