here's my '78 HEI refurbished. First replacement high quality cap, rotor, coil cover, and wire loom:
Coil in place:
Bottom of stock coil:
Everything in place and wire layout. Didn't have the adjustable vacuum advance on yet (adjustable up to 20 degrees, so I put 10 initial on it) and you can't see my springs which I think are currently two of the Accel red, or maybe one red and one blue:
Also I pulled the whole distributor out, disassembled and cleaned it. Then lubed it up real good so it is nice and snappy on the advance. After several decades it was really gummed up and the mechanical advance would stick. Big improvement.
