Pierre Gearhead Posts: 624 From: Near Paris, France Registered: Apr 2002	posted 11-29-2005 02:57 AM My cam pulls 15" at idle so I was thinking of either one of these options. What are the pros & con and in what case should they be used respectively ? Thanks IP: Logged

But....if you must,My choice would be a tank.Nothing wrong with 15 inches at an idle. Cory ------------------ 68 Fastback 427MR 4 spd.Deluxe interior,8000 tach,140 speedo,am/fm,tilt. IP: Logged

buening Gearhead Posts: 247 From: Decatur, IL Registered: Mar 2005	posted 11-29-2005 05:54 PM I have a CompCams XE262H in my 351w and i too am pulling 15" at idle. I have power brakes and air conditioning and have no problems with them working. Keep in mind that when driving the vacuum goes back up to around 20". Cars with A/C (at least 69/70 mustangs) have a small vacuum canister mounted in the rear passenger inner fender near the hood hinge. Not sure how much it actually helps but just an idea. ------------------ 1970 Grabber Blue Mach 1 H-code 1970 Fastback 2003 Torch Red Mustang IP: Logged
