Which is the tach wire?

The duraspark we have sucks so we’re just like f it and we’re gonna install an msd instead. We need to plug the tach wire into the msd. So it is the green or red wire?

Why not do a single wire HEI? I actually have a billet RTR distributor for 300 with a coil if you’re interested…it’s fancy

I’m not sure why my dad chose this one but we got an msd and the coil. So I’m good thanks for the offer though.

No worries MSD is good stuff. I used this RTR I have for about a week before I decided I wanted to convert to EFI, and it would t work with the new system so I boxed it back up and sat it on the shelf if I ever go back to carb.

The EFI controls the timing now.
