Hey folks, I'm finally getting around to sorting out my brake issues. The "issues" are legion (half-done disc brake conversion, dragging front disc pads, no front/rear proportioning valve, etc.) but a significant aspect is clearly vacuum drop or lack of vacuum to the brake booster. My '66 Charger has a 440 RB transplant with a pretty aggressive Comp Cams cam installed, and clearly there are issues due to the aftermarket cam causing vacuum lag/drop/whatever. Anyway, I want to install a vacuum reservoir as part of this next round of brake refurbs. Dead simple part, but I figured I should check on part recommendations, and any caveats or suggestions regarding brake vacuum management would be welcome.

Any of the Summit Racing reservoirs look perfectly fine. I gather a strong, reliable check valve is the main requirement (it's just a can, after all). I do want one with a gauge port. Is "capacity" an issue?
