The R4 ac compressors (new) are currently being manufactured by 4 Seasons. They build them for Delphi, and add the Delco/ Delphi stickers onto them. That said, they are also available here: www.acpartshouse.com First off a GM compressor is an R4 OEM compressor made by Delphi. Delphi subcontracts the manufacturning to another company. I do recommend you get a new one, but it does not need to be OEM new. The price at the dealer is a joke. www.discountacparts.com has new aftermarket and new OEM ones available.
i have a 94 cheyenne c 1500 4.3 v6 and it has a vortec
Yes as long they were mounted on the same side of the engine.

A 5.7 is a 350. Vortec is basically the type of head used.
230, it went to 255 in 1996 with the vortec
Vortec 4.3 should be 200 hp, however, it didn't come out until '94. Standard 4.3 is 160 hp.
No because the ports on a tbi head are different than the ports on a vortec head, vortec heads need a vortec intake however you can switch a carburated engine to a tbi engine because the heads are the same

Sure, with enough money, time, and all the parts necessary it can be done. My advice is to sell this truck and buy one that already has a V8. You will be money ahead.
You have to remove the engine cylinder heads to get to the lifters on the 5.3.
1996 was the first year that all GM trucks went to Vortec engines - it IS a Vortec...
The knock 1 sensor on a Vortec 4.8 is located on the top of the engine. You will have to remove the intake to gain access to replace it.
