MSD 2 Blaster coil with stock orange box set up??

[dustoff440]

Can I use an MSD blaster coil with a stock orange box elec. ign., everything else is stock except the coil.

Yes, but I would use the MSD recomended ballast resistor to go with it.

I'm running a MSD Blaster with an orange box and a .25 ohm ballast resistor in my 48 and the same but with the chrome box in the race car, the .25 is what Mancini said to use.
