Hi Ed, recognize your name from AAS. Welcome to the wonderful world of Cobras
I'm in Austin as well, and we have "meetings" (really gatherings for lunch and cruises) every month. Why don't you come on out and join us and you can see different kits first hand and chat with the guys about them.
BTW, since you're into Mustangs, you'll probably want to see mine -- Vorteched EFI 5.0
Next month's will be either on the 8th or 15th of Dec at County Line on the Lake (360 & 2222). Hop on to the Texas Cobra Club forum on this site and look for the post on Austin's December meet.
Cheers,
-Neil.
