I'm looking at the MSD-6A to add to my GM HEI. Anybody use one of these? Is there a better or more reliable unit out there? Good or bad experences? BTW it's going into a 72 Elky with a 454/TH350. Car is originaly a 350 2bbl.
Thanks for any help.

I have the MSD-6AL ignition box, it has been on my Chevelle for four years and have had no problems with it. I think the 6AL would be a better choice since it has a built in rev control.
