I use the regular cylindrical stock-looking high output coil, usually from the same vehicle that supplied the cap-rotor-wires, not TFI.

'hei' is a gm trademark. i don't understand why amc didn't do this from the start, unless ford wouldn't let them. note on drive gears - gm dist shafts are 1/2"; prestolite gears also fit, but ['78-up] duraspark shafts are 17/32". since i did my swap on a '68 i reused my original delco gear.

The two biggest matters you'll encounter will be bending " the dipstick a little bit to clear the larger distributor and changing " out the distributor gear. Neither are difficult.
