I think I may have found my problem with my loping, but just want to make sure. Right now my PCV valve is connected to the back of the intake manifold, and my brake booster is connected to the large port on the Holley 4160. Isn't this backwards? Shouldn't the PCV valve be connected to the large port on the carb?

Well my brake booster is connected to the large port at rear of carb and PCV is connected to a port on front. I believe they are both manifold vacuum sources.

typical configuration Booster in the back by itself.
PCV connected to the front by itself.
good luck.
