New 440 Build - Ignition Question

I've got a similar 440 setup. I use an MP electronic distributor from Summit. With about 37* total timing i get by on 93 octane. Or instead of buying a brand new distributor you could always upgrade a factory one to electronic, but you loose the easy adjustability of the mechanical advance. Spark plugs are just factory heat range plugs, although I've never played around with going hotter or colder.
