So the Mad Max movies are more like a documentary
I would use the pertronix unit first just to get rid of the points.
I had bad luck with the LED products (unilight) but very good luck with MSD. Just installed a 6A unit on the sled and it realy helps out the old garbage truck motor (big block).
Make damn sure your ignition wires are in good condition or you might find the experience a bit shocking. Also with the close spacing of the secoundary terminals on the cap you will need to keep a close watch for carbon tracking in the cap and crossfiring.
Also keep an eye on potential lean mixture conditions due to better spark/burn.
You also might consider one of the timing computer options and lock out the mechanical & vacuum advance in the distributor. This would give you alot of options for tuning the advance curve high rpm retard etc. And it beats the hell out of &^#%$ around with weights and springs.
If you can get by the bench racing bs the drag guys do have some good ideas that can cross over to the P-cars.
I didn't find anything disparaging in your post, besides I'm a public employee so I get abused and insulted all the time.
I would get a copy of the MSD catalog or visit the web site they have alot of interesting toys.
Hope the information helps I think you will find the improvements worthwille.
