A fellow owners has asked me a question.  He is running a fairly
high lift cam in his engine.  He had his 7 inch booster rebuilt
for big $.  At idle or when shifting gears, he is loosing boost.
No obvious vacuum leaks.  But at idle his vacuum is very
low because of the cam.  Could this be his problem?

What is the minimum vacuum the booster needs to work.

He is thinking about putting in 302 variable lifters to boost
the vacuum at low rpm.  Does this work?
