Just in case someone wants to make a set of MSD wires for P-Mags. Here's how I did it. Note: This is for a four cylinder setup.
The MSD kit includes a crimp block, wire labels and a tool to insert the wire. The latter didn't work for me.
No need for an expensive ratcheting crimper. The kit comes with a bunch of boots and terminals I didn't use. The boots and terminals in the terminal pack worked well.
Buy one each of these.
-Super Conductor Spark Plug Wire Set 8 Cyl 90° Plug, Socket/HEI Cap #31239
-LT1, 90 Degree Boots & Terminals, 8-Pack
-Dielectric Grease
Instructions...
-Pull a wire.
-Find an MSD similar length and cut it. Add some for posterity if you want.
-Lube the boot and an inch or so of wire.
-Insert and shove. Add lube as you go. Keep going till you ha e a few inches sticking out
-Use the strip block to strip what you want. I made the center conductor a little longer.
-Fold the conductor over the insulation and slip a terminal over it.
-Use a pair of pliers to squeeze it a little so it fits into the crimp block.
-Insert into the block.
-Slip the opposite block over with the two tabs on the same side.
-Drop it into the vise and squeeze. Don't over crimp.
-Remove
-Close the vise till the wire will slip through but not the boot. Slip it in place and pull till the terminal is flush to the edge of the boot. That's perfect for our P-mag coils.
-Test with an ohm meter. I got 100-200 ohms vs 400-500 for P-mag wires.
-Install. When you're finished, perform a pull through test.
Probably just me, but the spark seemed much stronger.
