Well, maybe buy a Superformance instead of building a West Coast? LOL. The kit came with more problems than delights and customer support virtually nonexistent - be careful who's you buy.
I'd put in an AOD which is on my list for next winter, as much highway driving in Krazyfornica happens at 80mph and up. 1: 1 C6 is a little high RPM for that. At least be sure your setup caters to the type of driving you'll be doing
