vacuum at idle
By bprewit - 02/22/2004 2:00:02 AM; IP 209.240.162.26
I installed the performer rpm cam in my 390. Edelbrock claims that this cam keeps 10-12hg vacuum at idle but I only read about 6-7hg. I have searched until i was blue in the face for a vacuum leak but cannot find anything not connected or plugged, or any leaks for that matter. Anyone else installed one of these cams? Any ideas? Not bad thing except vacuum advance dosent work correctly on distributor.
This thread, so far...

 You'd need 500ci to see 12 in/hg with that cam. -- Gerry Proctor, 02/23/2004
