[Chevelle-list] Vacum continued

[Jim & Chris]

I got the motor running again without the knocking / tapping noise. I measured 
the vacum  and it was between 11-12lbs. I am running a comp cams "High energy 
"cam that has 526 lift on the intake and exhaust. is that enough vacum or 
should I retrace my steps and look for more . Thanks, Jimmy C.
