Distributor
Its pretty hard to beat a Chrysler distributor. I’d use that long before ANY HEI type ignition.
Didn’t like the HEI when it came out, don’t like it now.
The Chrysler distributor, correctly curved with any decent ignition box (I prefer an actual Mallory box, not that **** that MSD is sticking a Mallory sticker on) is hard to beat.
