I haven't seen a schematic to study and see if it's true, but it's my understanding with the MSD box it can output up to 480V to the coil, so it only needs 1/20th as much dwell to get the same spark as a simple make/break switch at high RPMs when it's cranking the volts. I'm sure either set up is a 10 fold improvement over points and condenser.

MS checks the barro on the one sensor before you crank to learn the current barometric pressure. For mountain driving and aircraft use, the second barro is almost a must unless you run closed loop and give the O2 lots of leaway to fudge the map.

The fan control and a rev only based shift light are trivial in the set up. If you wanted the shift light to take into account MAP as well (so it became more an economy shift light instead of a race type rev limit pre warning) I think that's even possible.

Keep us posted. I'm interested to see how your turns out. I met a guy at a car show a few months back who had MS on a pro street 60's Mustang with a Cleavor. I wish I would have got his email. There's not to many of us brave enough to step outside of the box of what Summit offers in EFI.

I think the knock sensor will give to many false signals too. If I was to install one, I don't think I would let it do anything more than light a bulb on the dash.
