5'' on a vacuum gauge , take ur pic . Pulling it out of a blank location , I drilled and tapped the black mopar performance cover BLANK spot , same side as the pcv set up, SCREWIN CAP ON THE OTHER COVER I mentioned. W/ my solid .600 lift street roller it only has roughly 8-15 '' intake vacuum depending on rpm .
I had a freind thats called (mr chevrolet) by some around here tell me to do the pcv / sealed cap deal on a hot 406 sbc engine I had once, to bring it into the 20th century ,
" food for thot! !!". -----------???
Probly going to take the oil catch can off and run it with this set up for a while , I think my rings have finally seated .
