any msd is usually for hei afaik yes
stock hei is perfectly plenty enough as its at least 45k volts in stock form
no real need for anything more unless youre drag racing or some other crazy thing like that or for some stupid reason running a larger than stock park plug gap.
alternator will work in the truck if you wire it to the battery wires under the hood since a 61 was originally a generator truck
anything before 73 in the trucks was driver side alternator/generator
so if you want driver side still then you will need short water pump styler alternator brackets for pre-73 trucks, or car,
whichever style accessories you are going to run
as they changed and varied a few times over the years
as they did for the sbc engines
69-up in cars were long pump
the trucks carried old swp style accessories longer
good luck
