Just as a matter of interest since we're talking vacuum. Someone may correct me if Ive got this wrong I was told our Falcon GTHO's in Aust had both ported and manifold, no doubt to do with starting a high comp engine.

Also the effect of vacuum, today here is very humid and sticky noticed I was barely getting over 20Hg on a cool crisp clear morning I will get close to 22 Hg.
