Ok here are a few free or low cost effective mods:
-10chp-remove the "frisbee" from the front of your water pump pulley, see my site for details, free
-8chp-install cut-back stock style AC Delco spark plugs, details & pic on my site, $12-$15
-10chp-install a 160deg T-stat and aux fan switch; wire the aux fan switch to control the main fan relay, $80
-10chp-install a K&N with cut air filter lid, $40
Of course you will see some large gains from the more expensive exhaust mods:
-20chp-2 1/2" front Y, hi-flow cat, hi-flow cat-back, $800-$1200
-18chp-ceramic coated FL headers, $500-$800. This would be a nice alternate to doing the 2 1/2" front Y
The free mods will take your power level up from 240chp to around 280chp; then the exhaust mods can raise it to around 320chp.
At this point you should also install an AFPR so you can bump fuel pressure a little, as you will need more fuel flow at WOT.
Beyond that you can do heads, cam and intake mods to push very close to 400chp, maybe closer to 380-390chp and still retain or boost the low end torque as well as extend the upper RPM range.

I will remove my frisbee soon so I will let you know how it turns out. I am interested in this post because I am looking to do some of the more easy low buck stuff before I delve into the $$$$$ mods.
So far other than a good tune up and a K&N, the only mods I have made are a high flow cat and magnaflow cat-back. Not sure I can feel any difference. Hopefully the sum of many small mods will net a difference.
I think my next mod will be hooker 1 3/4 headers.

So don't expect a 10chp increase on the later C4 L98's.I got rid of my 3 lb.'er on my 90 with no adverse reactions but I didn't feel a big sotp difference either. Every little bit adds up though. So do it.

Rather than cutting back the spark plugs, take a look at the Bosch Platinum+4 plugs - $5 apiece.
They have 4 side electrodes that opens up the flame path and being platinum tipped they should last longer too.

I had them and had a low idle miss shortly after installing. I then switched to cut back AC delco rapid fire #5's and had great success. I recently switched to a colder NGK plug to run with my nitrous which brings up another thing..never run any platinum plugs with nitrous. Never.
