Re: Programmable HEI

If it doesn't pan out the adjustable MSD 6 series is really nice. I have had it on my 72 for several years. It does full timing curve along with vac advance and boost retard. The unit allowed me to ramp in the initial timing while cranking and still have a base timing in the mid 20 degrees! Only thing that sucks is that you need a laptop to program it.
