I would question the alternator connections. Guess it depends on which one you use but I'll throw in a couple of my concerns or questions if you're using the common 10SI. There are others on the forum that can give better advice on alternator wiring.

This articlehttp://www.oldengine.org/unfaq/10si.htm says #1 terminal is for a light. If so, I don't think you want it connected directly to the splice since that #1 terminal will switch to ground according to the description.

Going directly to the battery with the alternator output will mean the ammeter is not going to give a true picture of the state of things and will most likely show a continual discharge. Don't know how much output your alternator will have but the stock ammeter capacity is probably a max of 35-40 amps. In this case I don't think there is much option so something to be aware of.

Think we've discussed the carb switch wiring which would relocate to the new pushbutton on the Chevy but otherwise would remain intact.
