Carb swap and HEI
I want to swap over to the 2100 and do the HEI as well. I have the carb and the plate so that's all ready but the HEI is still a few weeks wait. Can I swap the carb now without any issues? Can I just unplug the stepper and install the 2100 without any issues?
I don't see why not. You will have to set your timing manually, and then you'll have to do it again when you get the HEI distributor. So extra work, but not a big deal. Your ICM will continue to work. You should nutter it, so the PCM cannot vary timing, but I think it will play nice regardless. I would not bother going through the nutter for a couple of weeks worth of run time.
