Wow...very few 5.0s posting. My turn. Bare with me...theres a lot to cover:
FRPP King Cobra clutch - Holds the power fine, but is very slow to grab. Makes the car come out soft for the first 10ft or so, then the car hauls tail. Its been in for ~3-4 years now probably, and I'm looking to replace it soon.
K&N filter & removed silencer - you know the deal...
Magnaflow catback - Great quality, good sound. Quiet at idle/cruise, opens up pretty good under WOT.
UPR Offroad X pipe - Good quality, easy install with the modular design. Gives a great 180* sound, sort of like the NASCAR Nextel Cup guys have.
MAC springs - rough ride, decent handling, no brake dive. Decent springs. Great for the price I gave ($75 shipped) I preferred my Steeda Sport Springs that were on my v6, though.
stock fox body GT front springs with my cut stock rears- junkyard said they were 4cyl springs. Junkyard was wrong. Never send your wife to pick up parts. They wouldn't give a refund
I threw them on anyway, and to my surprise, they lowered my car more than the MAC springs did, but rode a bit choppier, no doubt to the lower ride height.
stock '00 v6 springs with 1 coil cut front with my stock cut rears - Even lower than the stock fox springs, but again, an even choppier ride. I plan on soon dumping them for a true set of 4cyl fronts.
3.73s -
Nothing more to say, although a set of 4.10s would be nice.
bumped timing (15*) - a great free mod for all you 5.0 guys out there. Stock timing is 10*, and most guys run 14*. I've went as high as 16*, but settled on 15*, as it *feels* the fastest.
short belted smog pump - another almost freebie. No power gains, but if you've got an offroad pipe with no air tube, and/or deleted the air injection on the heads, it gets rid of that annoying whine sound the pump makes.
full length SFCs - homemade SFCs. Increased the stiffness of the chassis. Made the car more stable over bumps, and helped rid the interior of quite a few squeaks and rattles.
underdrive pulleys - nice SOTP difference. Cheap, easy, and good power increase. Everybody not going the supercharger route needs a set.
180* Mr. Gasket Thermostat - Car runs cooler, but would benefit more from having the fans turn on sooner as well. Definitely not wasted money, though.
MSD Super Conductor 8.5mm wires - good wires. shouldn't have to ever buy another set. The multi angle boots that you set by hand allowed me to clear the longtube headers.
Ported lower intake - free, easy, and good gain in power. I made 310rw/tq through that intake.
White face gauges - cheap, cool looking, easy to read.
Crane 1.7 roller rockers - again cheap (do we see a trend here?), good power gain. Recommended to anyone with a 5.0 who isn't looking to put a huge cam in anytime soon.
Nitto Drag Radials 245/50/16s rear track - Great tires on the track. Hook hard, and I've gotten 1.82 60' times out of them several times. I know they could get 1.7Xs, but my clutch comes out soft, and have yet to get one.
99+ brakes - great upgrade from the 94-98 brakes. Cheap and easy to do.
Ported E7TE iron heads - *cough* Free *cough*ported them myself, got good gains, easy to install. What more could you ask for?
Crane 2031 cam - idles good, very good torque (310rwtq afterall), good top end (i shift at ~5600rpm), great midrange. It gets along well with the picky '94-95 computer.

Flowtech Longtubes - very easy install with the slip tubes. I ended up having to remove one header and weld up the slip tube, though, as it was leaking. Still, the quality on these *cheap* headers leaves much to be desired with the BBK and MACs that are usually ran. The tube entries are dead perfect. the longtube design makes great all around power, too.
Cobra intake with ported lower - great increase over the stock intake. I'd estimate close to a 20hp gain. The intake has plenty of beef for porting, and even in stock as cast form, comes VERY close to flowing what the Edelbrock Performer does.

70mm throttle body - no increase in power at all, but good increase in throttle response. Definitely didn't hurt power.
Pro 5.0 shifter - on my worn out tranny, I hate it. Its a good shifter, no doubt, but my synchros hate me and refuse to allow high rpm shifts with this shifter and the short handle. I have since swapped to the stock handle on the Pro 5.0, and its better, but still not perfect by a long shot.
Aeromotive AFPR - well, it increases fuel pressure. It works. Uhm...nothing more to say really.
The above mods have been good for a 8.510 @ 81.95mph in the 1/8. Car has more in it with a better 60'. Between my soft clutch and 2" lower ride height with no weight transfer, the 1.823 60' time on the 8.510 run really leaves a lot to be desired.
