How Much Vacuum??

With it getting dark so damn early, I haven't had a chance to get out and tinker on this issue. I'll keep ya updated when I get a chance to get my hands dirty.

I think I have that cam in my 340 (I'll confirm later tonight) and I get 15 at 750 curb idle.

I'd appreciate it. Thanks! The cam was spec'd by Brian at IMM. I love the cam. Just gotta figure out this minor low vacuum issue. I'm sure it's probably something little.
