Here is my dilema...

[C-WAY]

aite...so I have a 2003 4.3 L v6 chevy...I was putting a 6.0 in it..My dad said he didnt want me to change up the motor..So Im going to have to wait about a year or so before I do that...anyway...I was going to add some modifications that will transfer over when I get the V8...plus let me have some fast fun while still owning the v6...tell me what u think of my list so far..

- Zippy Performance shift kit w/ corvette servo
- Rear end change from 323 to 373
- Electric fans
- Nelson Tune
- Torque Converter
- Add a custom fiberglass box/ containing my subs with a built in center console w/ a monitor slot, painted the color of my truck


What else guys?

sounds good for a start... good luck.. make sure when you change to 373 that you install a LSD as well... if yours is open that is.

looks like your on the right track but...
a big no no on the shift kit, servo, and torque converter since the lsx based engines do not use the same transmission that's behind the 4.3's.
