More Horsepower Needed!

Hello everybody,
I'm planning on upgrading the horsepower on the 'Vette this winter. What suggestions to you guys have? The only thing I'm sure of is a Borla Exhaust system and the K&N air filter (which I already have).

I would like to stay away from the 180 degree temperature thing because I'm not really that handy. I was thinking more along the lines of "bolt on horsepower", easy to moderate modifications.

Also, do any of you recommend a transmission fluid change? I have been told different theories on that and would like to get some feedback from other 'Vette owners.
Is your Vette a daily driver? Also, how many miles & I'm assuming it's got an automatic trans. There are a million bolt ons, but some of them will be better than others depending on what you use your car for.

It's kind of a daily driver; I usually go to work which is 14 miles round trip. I don't take it to go shopping or anything like that though. It has a little less than 89,000 miles on it; the engine seems to run strong at higher speeds and the automatic transmission doesn't hesitate at all.

The man who lives 2 doors down is a mechanc and he's agreed to help. This is a guy who restored a 79' 'Vette, a 69' Camaro SS and in the process of another Camaro.

I would like to know this, how much power could I safely pull out of my 5.7 liter V8?

On a motor with around 89K miles, I wouldn't suggest digging into the motor. Like you stated above, I would stick to bolt on performance. A nice set of ceramic coated full length headers into a Borla cat-back would be a nice start. That would give you a little more "oomph" and a real nice sound to go with it.
A rear end gear change will also be a very noticeable difference in performance.
There are also many different types of modified intakes that bolt right on.
