Skyman,

I listed my main mods but there is plenty of free mods you can do also.

Bypass the Throtle body. Basically, the coolant goes through it to prevent fuel from freezing in the winter but in the summer it heats it up for nothing. You redirect the flow around it to bypass it. Good for maybe 1-3 HP in hot weather.

Remove the screen from the MAF (Mass Air Flow Sensor). It will give you about 150cfm's more I think, not sure on that.

Power pulleys are cheap but try to get the one with the ballancer included, the cheap ones, you have to stick the stock, heavy balancer on top of them!

160 degrees thermostat you can buy for aobut $20 and wire your fans to a switch for free. I ran 5 runs in a row at the track with this setup and the temperature never got over the 1/4 mark! I could've ran all day long.

The biggest gain you will ever get with a bolt on is nitrous, the second one on an LT1 is Long tube headers. If you want to open up that baby it's the way to go, it would've been my next mod for sure! Another benefit from getting them is to be able to change your spark plugs a LOT easyer.

Make sure the Optispark, wires and plugs are in good condition, these cars are very sensitive to a poor ignition.

I am sure I am forgetting some but these are good starter points to go from. Definitely worth a full second when all done together.

If you know a machinist, get your MAF ported, fairly easy to do.

Oh yeah, NEVER run slicks on a stock diff, you will blow it appart. GM pisses me off for putting sucha weak rear end in such a powerfull car!

Don't hesitate to ask more questions if you want.
