Re: Swapped PCV & gained big time!
Sorry kind of late getting back here. I have had a good experience with this pcv valve as it cleaned up my idle and works as advertised.
My 383 pulls 15 in of vacuum and is currently running 18 deg initial timing with 20 deg mechanical advance in the distributor all in by 2000 rpms. I am running a vacuum advance can which is set to add 10 deg timing using the full manifold vacuum port. The carb is a Quickfuel Hotrod series 670 cfm with vacuum secondaries. Hope this is helpful!
