Will it run? Yes.

Will it be happy? No.

The injectors are different fuel volumes. On acceleration the mismatched injectors will be contributing differently to the system causing "misses". Also, the double pump of the injectors is most noticeable at idle. The AAs not designed to be fired twice in a row make a gnarly sounding engine.

you will need custom tuning to run the aa's in your truck.

i have a 96 cali model that i upgraded to ac codes. i had tony wildman do my tuning and have been running it for 4 years and no problems.

If you can get a Federal PCM (about $100 and something in the NAW4-6 range) and re-pin the harness connector your truck will become very tune-able. Singles are more reliable and that splits PCM can fetch you $800-1000 to someone that is trying to keep a stock truck going.

The two PCMs are not interchangeable. The wires are in different places. Near the connector is a printed sticker. There are three letters and a number. What does yours say? Example, my old Cali PCM was a MME2.
