I absoultly hate the 2.2
truck engine.
The car 2.2 is a diffrent animal and just much better. But that truck 2.2 has cost GM several customers. No you can't run the car 2.2 in your truck.
If you have to keep 2.2 for your states emissions then fine. But otherwise pull that failure prone mess and the 20 year old nest of wiring around it. Your interior controls (Including hvac) can be run standalone easily.
The 2.5 that came before the 2.2 is a much more user friendly engine that will bolt right up to the transmission.
A tbi 2.5 can be run standalone easily. My current build is a 94 with a 2.5 turning the 94's 5 speed. Running a later 2.5 will give you a serpentine belt setup.
Here you go. Harness, programed chip, and the ecm all in one package for $500 to your door to make running a 2.5 tbi plug and play. Just email them and tell them what your starting with.

The tbi regulatior (intrigrated into throttlebody) will have no issue running the with the 01's fuel pump pressure. It just sends the extra back to the tank. I have ran a inline pump for 2 years now that is rated for a ls(entire fuel system is set up for a eventual ls swap) on a 87 tbi without any issues with the regulatior or injectiors.
While the luv is a cool project finding say doors or fenders at a junk yard might be a headache.
You can still find body parts for the 01 in yards or if need be buy them new. Just check the reviews on the new parts fit as most require a bit of playing around.
