autozone carries a motorcraft sp-431A that is supposed to be a correct replacement. macs has a bsf42ca replacement as well for 4 bucks a piece. autozone will give you a better price.

I think a good modern plug would serve the purpose.

Sp_431A as mentioned at beginning of thread. I am changing the points over to pertronix so was going to change them anyway.

The SP431A is probably not the best choice for a 390 - it may cause pinging. It replaces a BF82 - a hotter 6 cylinder plug.
The typical 390 spark plug was a BF42. It was replaced by a Motorcraft SP420A. An Autolite 45 will also work.
If you have a high compression 390, it used a colder BF32 but that plug is no longer available.
