Master lock?

You have to disassemble it and remove the springs and tack weld the weights at full advance. I just loctited it, I have no idea if its holding up though.

How much boost are you going to be running? Why not buy the MSD box with boost compensator and run a direct fire turbo set up. That would be sweet as hell.

The MSD will only compensate for one MSD box, so basically just the leading.

There is an easier way that doesn't require dissassembly. You remove the screw that holds the top part of the dizzy shaft on, wrap some fairly thick wire around it and tighten it back down with the shaft at full advance. You could also tack weld it.

Because he is cheap like me! I think my system works fine with a locked distrubuter. However, I'm sure it would be better if I were using a TII ignition system since its not optimial for fuel economy and for utilizing the boost the best with closer to correct timing.
