I added the heater control valve because the heat blend door doesn't seal well and it was always blowing warm air. The cam is mild enough to keep the vacuum sufficient for EFI and brakes, as long as I don't have two panic stops in a row! But, now that I think of it the engine would stumble or shut off on hard braking with the carb and it doesn't do that with the EFI so maybe I'm ok. I don't want a practical test of that theory though.

Check valves are standard on that booster (it's a Bendix booster... those and some Delco-Moraine's had them right on booster, others were inline with the hose)
I'm waitig for Dr. Diff to come out with his power brake setup that runs off the PS pump (like older diesel pickups used).
I love Mopars so much I'm date coding the skid marks in my underwear.
I'd love to have hydraulic assist but I'm too cheap. It had a disc brake conversion when I bought it. I'd like bigger brakes, but again, too cheap. I've never been happy with the brakes but everything checks out including booster and line pressure.

I know.. only advantage I saw when I converted was not at as much brake fade when stopping hard... problem is we're stopping cars that weight 3700lbs with brakes designed for a 2800lb car..
I heard there is a pink Coronet running around out west with a set of 4 piston jobbies on it.. might be worth making a visit once spring hits and borrowing them..

Hydro boost are great and I have had good luck with electric Vacuum pumps on customers car with too much cam but they want to umpity ump through the parking lot.

I started the 46re rebuild with putting the shift kit in the valve body. I found two broken pieces on it so far. The accumulator spring was broken into 4 pieces and another small metal piece that holds a spring in place was also broken. I guess they are common failures because both pieces were in the shift kit. Had to drill a few holes, plug a few holes and file a few spots.
