Pompis,
Very useful info. Those Chinese are clever fakers, and are good at putting lip-stick on a pig. Somebody (273?) posted a photo of an MSD box that was empty inside, save for a little HEI module. ... They even go so far as to laser engrave fake SN's.
and it was the SAME fake SN...so if you ever get a MSD with a SN of 682013, you got scammed.. and the fakes DIDNT have torx screws on any of the terminal blocks. That video is pretty hard to dispute if all they did was change the ignition.
The 8 pin HEI's are overkill, Use the old ones as you dont have a computer to control timing events. just a reminder diagram...Dont mind the Ford call outs....
