    Yes, as mentioned in my original post, MSD 8981 timing computer (I think I typo'd the model #). Regardless of what the timing computer is-or isn't-doing, the timing light doesn't lie. I have the tc set up to deliver 20 degrees of ramped advance and it is doing exactly as told. My concern is running a supercharged motor with apparently over 44 degrees of total advance to get it to perform right. I've run normally aspirated sb Chevys and Fords with that much and more, but a supercharger changes the whole game.


    Until TDC is confirmed, I am not confident saying the ignition timing or the intake valve opens at 3 pizza slices BTDC.
