So I finally got this car turned on I know the engine has stage 2 cam and heads from coy miller. My question is would the cam affect my vacuum cause my stock bird at idle the vac is around 22-24in-hg this bird at idle is 12-15in-hg.
As far as I know, the larger lift of the cam, the greater loss of vacuum at idle.
I thought it was duration not lift that affects idle

My vote is Lobe Separation Angle has a major affect on vacuum
I would vote to say that all three would effect idle vacuum.
Tks Dave
Will take a couple of reads to fully sink in.
Can't find factory cam LSA in manual. Presuming 114 or 116
So with 218/224 112 lsa I will be running pretty low? (motor not installed yet)
