Not strictly an FE question, but it is about my FE. I don't have clearance with the short Ansen aluminium valve covers to use a rear breather. I've been looking at changing the valve covers, but the only cast ones I've found are the tall Ansen covers. From the specs these will probably touch the brake booster, if not when I slam it, there will be contact and I don't think I want to put in a torque strap to prevent that.
The other possibility is a smaller booster. I'm a little concerned that with the relatively low idle vacuum I won't get much boost out of a smaller diaphragm. I don't know if the old Ford booster is single or double, and I can't find any info on the amount of boost I can expect out of a smaller booster with two diaphragms.
Does anyone have any guidance to offer? I've looked at hydraulic boost kits on line, but they are expensive and I don't see any that fit an F100.
