Which Distributor?

I've got a 340 in this Valiant of mine.

What vacuum advance distributor would you recommend to run? (Mopar, MSD, MAllory)

Not currently running with the advance. Just think it would be better for street purposes. Mostly street driven, but some strip (8.90's 1/8 mile). Going to put MSD ignition on it in the spring too.

Thanks ahead for the feedback,
