cam profiles play a big part of what vacuum you will see.

At idle I see around 12-13 ". But I believe you are running a larger cam than I.

A little larger cam but for some reason i thought due to the dur. the 5.0 had to have there would be more than a crap-e 8 at idle

you may be correct. that does sound low

I get around 15 at Idle. Usually 10 at cruise.

not meaning to intrude into your thread, but where is the best place to hook a vacuum gauge to? does it have to be like the pcv line or what? sorry for the intrusion, i am trying to diagnose a light throttle miss, and was gonna put a gauge on my car..
