To Vacuum Advance or Not to Vacuum Advance

Wow... you guys really got me wanting to change my mechanical advanced MSD distributor to a vacuum advance one. Had no idea there were that many benefits. Lol.

Now the question is which one do I run for an aluminum head, large cammed hydraulic roller 408? And what would be compatible with my MSD Digital 6+ ignition box?

That is what I did, got rid of my MSD for a FBO distributor. Give Don a call at FBO he will curve one for your engine. The distributor he did for me with a vacuum advance ran great out of the box. I do believe you can run your MSD box just make sure you ask him for the correct cap so you can keep your current spark plug wires.
