Once again, if your just going to power up a couple of 12v
devices the small voltage booster cubes fit right under the
dash, one wire to gnd. and one to a hot spot and you're good to go.
I power a SunPro 12v tach and Sony AM/FM/CD stereo from one:

As far as starting goes if you have a good 6v battery, proper
sized cables, solid clean connections and a good starter then
starting is not a problem with these stock 216 or 235 engines
and the lighting system is perfectly adequate.

You won't be able to fit two batteries that have enough cranking
power into the space where one lived, so you will have to find
another spot for the second batter. The wiring would be a real
pain in the ars and you will have to rig some way of putting
them in series to the starter and 12v accessories and then in
parallel for the 6v generator.
