XE 268 cam

How much vacuum should I have at idle?
In park I have 11" and in gear 9.5"
The engine is a 340 cast iron exhaust manifolds and a spread bore 71 intake.
Car seems to perform well but it only has 1000 miles on a rebu

I have this cam in my 318, That's about the same readings I get. brasil is right, this cam seems to like a little more in terms of initial timing.
