Do a search for this, it has been covered in details. The common way to do this is with a Duraspark distributor, which means getting one for a roller cam, adding the fuel pump eccentric to the cam, getting a timing cover for the mech fuel pump, (or use and electric pump), a suitable tank pickup. Also need the intake, throttle cable.
The alt wiring should not change. The ignition needs power when the key is in start and run. Not familiar with the Accel unit, but I have an MSD Digital 6/Duraspark dist in the 82. I think I have the original Duraspark box power wire (not the coil wire) turning it on and off. Really not much to it. Best to consult the manufacturers instructions.
