Best Electronic Ignition Setup for a 273

Hello all,
Doing a slant six to 273 conversion. The 273 I picked up has points. Would like to convert it to electronic ignition.
Would like to use a factory Mopar setup from perhaps a newer 318?
Does anyone know if a 318 electronic ignition and distributor will work on a 273?
If not, what are my other options?
Thanks in advance.
I don't know about 273s, but I can tell you that I put a complete MSD system in my 69 340 (mechanical advance distributor, coil, plug wires and ignition box). It was a huge improvement. The car starts, idles and runs better than before the swap. It was an excellent investment.
