How much vac at idle with a mild cam

How much vac at idle do yall guys have that run cams close to 218/218?

Ive got a 204/214 and if I recall vac was 12+ in D and 15~ in P/N.

It's weird how it can vary from car to car. My vacuum stayed the same with everything from the 200-200, 210-205, to the 204-214. It was never lower than 17" in D. I wonder if my smaller, looser convertor has anything to do with that. 218 degrees is kind of big for a 3.8L. What else do you have to support it?
