I dont know anything about bolt on EFIs but I think vacuum should come from manifold and dizzy should be locked.
So any distributor should be fine.

Pointless pickup is almost must thing to avoid noice on RPM signal.

If going to another form of induction on a 54/56 FYB, you need to go with the 57/ style distributor as the proper vacuum signal(s) cannot be supplied for the original Load-O-Matic feature.

Ideally, the later distributor should have at the least a PERTRONIX upgrade (IMO) to provide a hotter spark.

Good question.  I have no experience with them and I'd really like to hear from someone who has.

Anyone here running the holley efi steups? Looking at the sniper tbi. Wondering what to do as far as a distributor or if the 57+ ones will be fine with it.
