Want to improve ignition....

Don't underestimate the advance curve, and try not to force-feed your engine advance. IMO, 2 to 4 degrees not enough timing, is better than 1* too much; sneak up on it.
I think that's true, and certainly the safe way to deal with the mechanical curve.

I have to disagree on the FBO plate, especially for someone taking it to the dragstrip. It limits the advance instead of increasing the initial. Too many people get fooled into thinking that quick advance off idle is OK to keep going to 'all in at 2500'. That's fine with no-vacuum advance for 1/4 mile runs, but costs top end power and is too much mechanical advance in normal driving to work with vacuum advance. You may remember that for years Don's stuff didn't work well with vacuum advance, and he recommended not using it. My guess is he's addressed some of that now in the package deal, but for the FBO plate alone, the issue remains.

I had a Accel Super Coil on the firewall, upright, and it leaked oil. In retrospect I'm not sure if I caused it to overheat or the top seal finally gave out due to quality of manufacture. I'd have to dig back to figure out if I was running with a Chrome box or had switched to the MSD 6A when it failed. It is a pretty good coil when matched with the correct resistor, and was the recomended coil with certain chrome boxes.
