Mustang Ignition

Hey I'm really stuck and need some advice, anyone have any comments on a steet/strip ignition system? I have a '66 Mustang with a 289 +.030, 280* Comp Cam, 1.94"/1.60" valves in small chamber big plug heads, other stuff, and was wondering if if there are any performance values to adding MSD 6AL, Dist, Coil and other ignition parts. I know that it will yield more of a consistent spark pattern, easier starting, and maximum burn in chamber if done right. Other than more reliability will it help make more power in the sense of cost/effectiveness ratio? Any help would be appreciated!
Thanks!

In the dyno tests I've seen, there was little difference in hp between different ignition systems, but like you have suggested, there is the reliability factor of a good ignition system.

Here is one source that I will try next, having been through all the MSD, Mallory and others through the years. It's a self-contained unit and they will curve it for you to your specific car and driving requirements. Add a good set of wires and you're done....

Thanks for the help I already checked out the site from the link you gave me and it looks "purty" good as we say in Alabama. I am also having a problem with pinging and I haven't really tweaked the timing so I am hoping that will fix it. Shaved 54.5cc and flat tops seems to be a winner for compression but trying to get decent gas and octane boost seems to be a problem. Once again thanks for the help!
