value question [for my parents sake, kinda long]

[Tom]

Guys, me and my parents were talking the other day [well almost fighting actually] and it was about what my truck was worth [or lack of worth according to them]
So Im posting this looking for some opinions and Im letting them read the replys. I have almost $6000 in recipts for my truck in a folder. Ive kept all recipts since I bought it

Ok so heres all the new stuff on it:
-vortec 350 with RPM intake, carter 600cfm carb, Hei with MSD coil+module [almost 10,000miles now]
-2004R built for 450hp w/2200rpm lockup convertor [5,000miles]
-western chassie flip kit+c-notch
DJM 3" spindles, eibach 2" progrssive rate coils
-255/60/15 tires [5000miles]
-aftermarket 15" rims [nothing speacial]
-complete kicker sterio using a component set of 6.5" mids and 1" tweeters in custom kick panels, 5 channel amp and 12" sub with a JVC cd player.
- new fuel lines, radiator hoses, motor mounts, spark plugs and wires, cap+rotor, carter electric fuel pump, holley pressure regulator, water pump, flexi fan, fel-pro gaskets inside the engine
-2" ramhorn manifolds to dual 2.5" exaust with catco convertors and flowmaster 40series mufflers with Z28 style tips
- a few extra guages here and there inside the cab
-TCI flexplate, ARP head bolts and flexplate bolts
-B&M tranny cooler

Ok thats all I can think of right now, although I know theres more. Just a rough guess would be great. Thanks guys!
