Run the MSD stuff, 7al2 or 3, and an East Coast mini alternator. You can hot-lap that dog for hours and it'll always start! I ran Vertex years ago, they have a very small coil and like others said very little spark energy when cranking. Don Zig and others converted them to external coils and hotter magnets - that helps but it's still a magneto. I also ran Mallory Super Mag III for a while, good units w/ an external coil and still kinda the choice for sprinters. Also once had an MSD 7X box that I swear could cut through 1/4" steel! You didn't want to get accidently hit with that! 8) JB

Too much upkeep and tend to have a lot of spark scatter.

If you decide to stay with MSD or Mallory, I highly recommend that you go to an Optima Yellowtop battery. I, also, don't run an alternator, have electic water pump and fans, which I run between rounds to cool down fast, even a bottle heater, and can run four passes with no problem between charges. Awesome battery. Regenerates itself. I have thought of going to two of them, think I could run all day without a charge.
