440 Mechanical six pack PCV valve ??? - 10/09/19 12:13 AM
Hi gang, I'm looking for input for a PCV valve for a hopped up engine with 12 inches of vacuum at idle in park. Oh and it can't be made of unobtanium.
I started with a Fram PV163. The idle was so high I could not adjust the carbs even close to seeing the transfer slot.
I then did a web search and learned that a valve from a s10 2.2 liter flowed significantly less at idle. So I installed an ACDelco 19313315. The idle dropped significantly and I think I'm going to stick with this PCV for my larger canned engines.
Thoughts???
Thanks!!
