P.S. as an aside I called Fram tech support to see if they had any specs on the PCVs that some said are better for our application, i.e. low idle vacuum, He knew some were for some GM and Ford hi-perf engines but could not come up with any real numbers, so I opted for the adjustable one rather than guess.

i crossed the part number that was the Mopar Performance valve and somehow i came up with an application for one of the 4 cylinder dodges from the 90s i think it was.

it was significantly lighter weight than the PCV valve what was on the car, which i imagine was a factory 318 magnum application. i haven't started it yet so it will be interesting to see if it makes any differences.
my motor has 13" vacuum at 850rpm idle in neutral.
