What type of vacuum would you expect to get out of a stock stroke 440 with 252/260 @ .050 duration. Cam was degreed in at 104.5 ICL, its a 110 LSA Comp.

32 degrees of timing locked out on the MSD Pro Billet. I'm getting a fluctuating 6-8 inches at idle. I don't really care, I just expected closer to 10, and my desktop dyno is telling me 12 (which seems very optimistic). I have a 6.5 PV in there now so I'm going to swap it out for a 4.5, and I'm thinking that should help stabilize the reading closer to 7/8.

Just looking for some input. Throttle response is good, doesn't appear to have a vacuum leak checking with carb clean. I'm just trying to get this thing squared away before I venture out for some WOT blasts on the street.

Now I need to pin those needles, got to feel that heat
