    hey guys so I wanted to hear your experiences with MSD BOX 6al, I know it produces multiple spark discharges up to 3k which lays around were I do most of my driving, what were your gains and experiences? I'm currently running 73 up dizzy with Ecu module. I tired HEI but failed every other month so I'm done with that. Yes I know it's pricey but that's why I have a job.

      I run a 6al it runs smoother and starts way better! Changed from a tach drive chrome box to 6al and billet dist.

        Which HEI modules have you tried and do you have your module mounted on a heat sink with a coating of heat transfer grease? Is the coil in the proper resistance range for the HEI ignition? This module is highly rated, this will probably be the setup I use when my orange box gives up the ghost.

          I had pretty much all the brand available, the Davis lasted the longest they all would burn out on the highway, it was a big difference though when I had it on my car.

            Not to mention the better module options (I believe) with MSD. Two step launch controllers. Multiple dial rev control modules. Full coil and distributor performance product matching. And of course upgrade to digital MSD system if tighter spark control is needed for higher HP and RPM builds?

            I'm not up to date with HEI options. But so far with MSD? I don't have to be.

            JMO of course.
