I have a 77 blazer with a HEI in it. I just picked up a new unilite from a buddy for free . I also picked up a msd 6al ing. box from jegs. I'm looking to install the unilite but there is no instructions on how to go from hei to a points style of distributer. The msd ing. box is easy once i figure out how to install the unilite to the factory hei wires. And then there is the question of a ballist resistor or a capasitor, do i need them? Any help out there on this subject?
