You'll have a good start on the suspension end of things. With the heads & intake, I can see your ET dipping into the 12.80's or maybe a little better. Figure on upgrading MAS, injectors, cam as well as some of the other bolt-ons such as roller rockers, ignition, etc. Add a Pro-50 shift and get the car down to 3200#; don't forget about axles and a rear-end girdle. This year you're going to need to run 12.50's or better to be real competitive and 12.30's or better to be in the top echelon. I fully expect to see some of the T/S guys go into the elevens, and they're making preparations for doing so.
It may sound like a lot, but it doesn't have to be done all at once. Its a game of picking up hundreths of a second when you've got the time and money. Good driving, something that eluded me last season ;^), can make up for a bundle in go-fast parts.
