I haven't seen (or heard) any signs of detonation on the plugs or pistons.

The more I think about it, the more I think I'd like to have a vacuum-like curve, and more programmability. I'm thinking of adding an MSD 6AL-2 Programmable and a MAP sensor so I can get those benefits, or maybe a CBPerformance box.

I have used both boxes, and the CB Black box is the winner in EVERY area.
Great value for money.
I will not run a mechanical/vacuum only distributor on it's own from now on.
