MSD capacitor box replacement...

I've always been a fan of the Accel 300+ / 375+ ignition boxes, they take a beating. I don't think they make the 300+ anymore though, last time I looked online I didn't see it on Summit or Jegs.

I have the 300+ in my truck, and it has survived multiple 18+ Volt Spikes during regulator failures, survived low voltage situations, etc.

My Duster has a 375+.

The 300 (and 375) have adjustable rev limiters, etc built right into the box.

The 375 has Boost Proportional Timing Retard, Cranking Timing Retard, 2 Step, etc, plus a Digital Readout for RPM, Vacuum, Boost, etc.
