Recommended Mods? Hi im wondering ive got a 95 LT1 Vert. and im in the begining stages of moding. what mods do you guys recomend that give the most bang for the buck as i am on a budget becouse i have to ship the items everseas the mods that im thinking of are as follows.
Short tube headers and y pipe
Exhaust
convertible Tonneu cover (if thats considered a mod)
Strut Brace
Subframe conector.
and the car has a CAI alredy
so give me some ideas of what culd work well or if anything ot that list is money better spent else where..... also there is one thing bothering me.. i wuld like sport springs but lowering the front end is not an option as the front end is way to low alredy but if you guys know of any springs that dont lower the car do let me know

They are not a waste. I would say that it depends on your goals with the car. If he plans on lowering it or staying emmisions legal then this is where the short tube headers are going to come in.
I am about to do away with emmisions on my car at this point as i am getting more serious ,so i can say that i wish i would have bought long tubes however. It all depends on your goals again. I have some coated SS shorties that make my car flow good.

mods The mod I did that made the most difference was the gears.
I have an A4 Z28 LT1 and it had 2.73's
I put 3.42's in there which I bought from a message board and it knocked .3 of my E/T and it really woke the car up.

Gears will be the best bang for your buck. As far as shortie headers I've heard there is basically no real horsepower gain, but I have never known anyone who got them. If emissions is not an issue I would go with LTs.

cutout, 30 bux 12 rwhp....check the stickies at top adn you will see the price range and the power expectations for each bolton modifications. cold air kit and cutout will give you the most hp increase for bang for the buckl bolt ons, plain and simplce.
I'd vote for exhaust, tires and gears, in that order. I've seen a number of otherwise stock LT1s run 12.9s with exhaust, tires and gears. My gears and tires are on the way 
You can see from my times that with traction (1.7 60ft) I could run a low 13. With some gears I hope to bust 12s as well 
I went with 4.10s as well. Most people will say 4.10s will turn too high on the freeway with an auto, but I figure that if I was that worried about gas mileage I wouldn't have bought a V8.

Yeah. I also recommend for auto cars: Exhaust, torque converter, tires, gears in that order. Full bolt ons and tires for an LT1 will get you on the 12's.

Shorties are better than stockers, mids are better than shorties, and LTs are better than mids, powerwise. It's all up to the person, whether they want to stay completely emissions compliant (I.E. Shorties with CARB E.O. # and AIR/EGR) or if they want power (I.E. LTs).
Personally, when the time comes, I'll be going Pacesetter LTs with AIR/EGR, due to the fact that I can get past the visual, but the sniffer I still have to pass.
When it comes to what an LT1 responds good to, I would say headers, exhaust, and a CAI are good to start with, then it just depends on how far you want to take it from there. Another thing I would recommend getting is a set of rear-end gears, these are a good bang for the buck item. If you have a T56, I would recommend 4.11s and if you have an automatic, then I would say go with some 3.73s. Put all of this on your car and it ought to run pretty good and be streetable, but mods also are restricted by state regulations, and how much extra money you have (thats my case).
There are also "free mods" that you can do to an LT1 if you would like, these will help it out some, but dont expect too much. The two I have dont on my LT1s are
1.) Throttle Body Bypass
2.) De-Screen The Mass Airflow Sensor
