thanks for the info. !
I have a MSD box that is black with mopar on it. Has a 6000 chip.( Basically a 6al box I believe )I have a stock electronic dist that I will be recurving. You say with RPM the box will pull timing out ? I didn’t know that.
Yeah, it will retard with RPM. I could post a video of it happening on my machine, but I caught the poo poo the last time I posted it here, so I will go find the third party video I saw that made me buy my distributor machine.
I figured if it was true that ALL ignition boxes retard with RPM (and it IS a fact that they do) then it’s near impossible to set an advance curve without a test bench.
So I found my and bought it. And I have verified it happens.
I’ll go find the video and post a link so you can see it happen.
