My 79 280 SE runs fine when cold, but when hot, misses and idles
rough, poor acceleration etc.

Any ideas what might cause this?

Coils have been known to go bad in a failure mode that
leaves them working when cold and weak when when
hot.

At this age, you probably got a pretty good vacuum leak somewhere... then
check all basics... such as distributor cap and rotor... that when it get
hot, will misfire... forget what reason... like crack, etc.
