Msd 6a or orange box

Well I'm running a mechanical distributor, 36° total with 93 octane. This msd should help over stock base ignition.
You have read the MSD claims in the instructions?
If have found them to 100% credible.
On the strip, between the MSD & the MP chrome box, I couldn’t find a difference. I didn’t have a fine tuned machine constantly running the track. It was just a quick test with a crappy driver.:lol:
