-With my purple 292/.509 cam, I had around 10 inches vacuum at around 750/800 rpm,and IIRC around 16* idle advance and 11.1 true C/R.I did not need the vacuum reservoir, though I contemplated it during the planning stages.
-If you have only 11 inches with the 284 cam, I suspect that you may not have enough initial timing, or your C/R is not as high as mine, or your trying to idle it too slow.I know they sound great at lower rpms and with late timing,but I worry about my cam lobes so idle mine closer to 800 for a tad more oil.It seems to be working. My engine has 125,000 miles on it with maybe 100,000 of those with the current Hughes 230*cam and their spring kit,Which I shimmed up for a little more security at 7200 rpm.
-My Midland has always worked great.I chose it over several other types in my stash because of its rebuildable feature, its compact dimensions, its period correctness and, its handsome good looks. It has worked flawlessly for nearly 15 yrs.
-I installed a combination P-valve from a 73 Dart.Later, when I fit 295s out back, I found a bit more braking power by gutting the valve, leaving the brake warning system alone, and swapping out the wheel cylinders out for 1 size smaller.The car stops awesome; easy to modulate, powerful, and has been 100% reliable. I think in day to day, around town, sub 40 mph,that the back is actually doing a lot of the work, as it wears the shoes faster than the pads. But since it has no tendency to spin under very hard braking and, hauls the car down really well, Im not touching it. I had purchased an adjustable P-valve early into the project, thinking that I would absolutely need it. Its still on the shelf in its bubble pack.
-I had to narrow the rear to fit the commonly available 4.5 backspace wheels.I had to move the springs over with the 3/4 inch offset kit,and moved the rear back another 1/2 inch to fit 325/50-15s for track days.
-One summer,I put some sticky 245/50-15s on the front. That was a fun 8 wks until I wore the treads right off those babys. Can you imagine that? They were some soft tires.The next month I put the 235/70 14s back on. The fun-factor was too pricey for me.
-Ah the memories.
