Thanks    The one thing my son really likes doing is going to the Woodward Dream Cruise.  If you don't know what this is, here is a link to what it's all about http://www.madmanmike.com/woodward_dream_cruise.html.  If you are in driving distance of Detroit, I recommend going.  Lot's of cars and lot's of fun

Looks good
If you plan to keep the drivetrain basically stock, you can upgrade the rear with OEM components with no issues. They only get weak when you start putting more serious HP to the pavement.
As for the engine, get a cold air package, a good exhaust system, and a pro tune on the computer. It will really wake her up.
Yours manual or auto?

I've had several Firebirds. Atleast one of each generation and bodystyle.
'68 Firebird 400/auto convertible (with A/C)
'75 Trans Am 400/auto
'87 Firebird 305/auto Ttop (this one a had the longest, I upgraded her to a built '89 Corvette L98, 3.23 posi, and discs on all four corners, race tuned suspension, and plenty more. I autocrossed it competitively for about 5 years before we built a dedicated racecar. It was a fun car
'89 Firebird 305/auto Ttop
'89  Trans Am 305/5spd Ttop
'95 Formula LT1/6spd Ttop
'96 Trans Am LT1/auto Ttop fully loaded -the CD changer

Redbird- A cold air package?  Are you talking about like the one sold by SLP?  I'd like to do the exhaust, but honestly, they command a lot of money for a good system.  If I swap gears and do a tune, I think I should be happy.  I'll start with that first

Yes, I had the one similar to this on my Formula...

Keep an eye on eBay/CL, they pop up all the time.

Think about just doing mufflers then (or maybe a cat-back system). The key is to lose the restrictions in getting air through the motor.
Also, check into the F-body forums. They're good for info and classifieds. LS1.com used to be the "go to site" for 4th gen performance. I haven't been on there in several years though.

There were so many options to do with my hood, but ultimately I just wanted simple and clean.  I think this fits the bill perfectly.
