Best place to pull vac from???
It's an iron 408 n/a build strickly for the street, maybe the track once or twice.
My ring package is the GFX rings from Wiseco; 1.2×1.2×3mm. I have the gen 3 ls1 syle valley cover. Also have the proform slant edge valve covers w/ baffles.
So should I use that and pull the vacuum from the valve covers like the way an ls1 pcv system is run except I will be using a mechanical vacuum pump, either GZ or Moroso.
Or should I grab an ls6 valley cover and pull the vacuum from there? Thanks for any help on it.
