When installing and wiring the power relay in order to "guarantee full line voltage to the ignition module at all times," can I wire both terminals 86 and 87 to the coil (+)? I'm thinking this should work considering:
a) terminal 86 "is your trigger feed. This one needs a 16ga wire that's live when the ignition is switched on." The original coil pickup (+) should supply power to the coil and relay terminal 86 at this time???
b) terminal 87 "is your power output. Connect this to the coil (+) and to the module's power terminal."

Is this correct?
Thanks a bunch guys!
No. Terminal 86 needs to be connected to a power source that is live when the ignition is turned on (both in start and run). Terminal 87 is the clean "full power" output of the relay.
You can use the original coil + wire as the power feed to terminal 86. Then you should connect terminal 87 to the + terminal on the ignition module.
In other words, leave the factory + wire going to the coil. Make a new jumper wire that will go from the coil + terminal to terminal 86 on the relay. Then connect the module + terminal to terminal 87 of the relay.
If you wanted, you could hook the old coil + wire to terminal 86 but do not connect it to the coil. Then you could power both the coil and the HEI ignition module off of relay terminal 87.
A) both. The vacuum amplifier goes to the vacuum amplifier port and the EGR line goes to the poerted EGR port.
B) neither carb did/does have a port for the brake booster. The brake booster connects to the vacuum tree on the intake manifold.
C) the distributopr vacuum advance hose connects to the distributor vacuum advance port on the carburetor. As you look at the fuel inlet on the carb, the correct fitting is below and to the left of the float bowl.
A) That HEI write up for slant sixes says: terminal 87 "is your power output. Connect this to the coil (+) and to the module's power terminal." So you're saying this is incorrect and only connect 87 to the modules (+) terminal?
B) The image attached is a 6280 with a brake booster port. You'll notice on the attached image that there is only one EGR fitting. So I have one EGR hose. My question was to which EGR fitting on the 2280 do I connect it to?
The 2280 diagram you've attached- interesting how the labels are all incorrect on the lower left diagram image.

No, you can do it two ways. If you only want to power the ignition module wiuth the relay, don't connect the coil + terminal to terminal 87 on the relay. If you want to power both the coil and the module through the relay, connect them both to the terminal.

THANKS!
Only some carbs have the dual PCV/Brake booster ports. Most just have the PCV port. THe diagram I posted has the heated air and EGR fittings reversed in the lower left picture, yes. That is a scan from a factory Dodge service manual, so somebody dropped the ball during proofreading. I would connect the one EGR hose to the EGR fitting.
Great, thanks Reed! One last thing. I'm left with a ESC (electronic spark?) vacuum line with no more available ports. Should this go to the intake manifold vacuum tower?
It doesn't matter. If you are abandoning the lean burn systems then that vacuum hose is redundant. However, the vacuum line connects to the lean burn transducer which requires a soure of manifold vacuum. On carburetors designed to work with lean burn systems there is a port on the carb for the "Electronic Spark Control [ESC]" that provides the correct manifold vacuum. If you are eplacing the carburetor with one not designed to be used with a lean burn system then the ESC hose can be connected to any source of manifold vacuu. The vacuum tree or "T"'d into the vacum choke pulloff line.
