IF your orange box isn’t 20 years old, then throw it away. It’s junk. The only possible use it is good for is;
To give to your enemies because I sucks
Use as a paper weight
Use as a fishing line sink
Toss at your cranky neighbors head
Take it apart so you learn what not to use
Hang it on the wall of shame.
IF you want to use the stock style ignition box system, use the chrome box. I have found the chrome box slightly better than the msd at the track. Th msd is slightly better at idle and LOW rpms. IF it doesn’t fail on you!
