I'm still a ways away from building my car but do have some questions regarding going to the MAC Center. I would like to run the MSD Atomic EFI system but would that be a problem since it doesn't have OBD-II? I want to run a stroker motor, something like a 289, 363, 374, or 427 small block. A DOHC 4.6 would be my backup plan if I couldn't get the thing register. Any experiences/advice?
