Re: Thinking of going from MSD to HEi
I have the MSD Digital 6 plus on my Chevelle with an HEI MSD distributer (coil in cap). I keep the HEI insert module for the distributer in my trunk to quickly convert back to HEI if the MSD Digital 6 plus fails. The MSD digital 6 plus has failed on me a couple of times through the last 10 years or so, but, I keep going back to it from the HEI because of the multiple spark. Bottom-line, I can just get my big cam Chevelle to run cleaner and more efficient with the MSD digital 6. The box just gives you that extra energy to really clean up your idle and low load conditions.
Bottom line for me, the MSD Digital 6 plus is not very realiable, but, has a great multi-spark that I really like. The HEI is very, very reliable, but, I miss the multi-spark with my big cam.
