You might recall that I am running stock FI intake and TB. Last  March I 
drove
to PH and had a vacuum gauge Teed into the vacuum line to the  stock 
distributor.

At a steady 67 mph at an altitude of 6163', I had 6"  of vacuum. Now 
granted I
have a slightly larger than stock 1776, but that  should give an idea of 
how much 
advance was being added at that point.  Maybe someone with a vacuum pump 
could tell us what 6" at the canister  yields in degrees of advance.


This  might be a job for someone with a distributor machine. Although, I 
think if 1  had a digital timing light, and a vac pump, it might be possible 
to get an  idea of how much it changes. I think the hard part might be 
getting just 6  inches of vac, so a reading could be taken, as I don't really know 
how much  vacuum is made thru the fitting on the FI port (normally). That 6 
inches of  vac doesn't sound like much, and more like having your foot in 
it. ;-)
