Do you have a Bosch XE type dizzy? It's self-contained and will be more than adequate with the stock module and an HEC-716 type coil after recurving.
If you get close to 12 second quarters, you might need something like a Crane Hi-6 module. They and MSD are the only ones dyno proven independently, to enhance performance in a decent measurable fashion. Otherwise, they're just there for the wrist exercising factor...
