borrow some manifold vacuum

moper your absolutely right and I am also going to install a shroud and go back to a factory fan. However, since the point of ported vacuum is to actually make the motor run hotter on purpose, and I'm chasing a smoother idle anyway, I thought I'd give this a go too.

After 67Dart273 comment, I visited the holley site and that hose isn't in their manual. So I took it off, blocked both ends, and went for a ride. The motor seemed to run a little smoother. I think that manifold port just became available!
