Will it fit, and will it work?

I do know that some enignes had a 1/4 hex and some had a 5/16 hex oil pump drive that you need to consider. Can put in a 70's electron dist with a gm 4 post modual to fire it but need the correct coil. I believe a 2 ohm I used one from a BMW from ebay. this is what I did for my 289 1968 ford motor with a full 12 volts to dist. ed ke6bnl ,for the 170 motor I did not complete the install so this is what I had started to gather.
