Ok you have gotten a lot of good advice, so I won't duplicate any of that, but I'll try to mention only stuff that has not been mentioned.
Obviously you had issues with the intake and you are getting that taken care of which is great. Getting the updated spider injection is a must do, I'd put a new fuel filter on it to.
But the vortecs with the pancake style ignition cap are known for failing in weird ways. Everything from hard starting to sudden misfires and backfiring. Can happen on a cap of literally any age or mileage. At the shop we will only use ACDelco cap & rotor as they are the only brand that doesn't seem to do this. I only mention this so if you get it back together and it still isn't running like it should, this would be a good next step.
Oh and for the record, I think that the stock vortec's are great motors, but just like any other motor they have their idiosyncrasies. I've got a 1999 454 vortec in a class c RV. Also I would not hesitate to own a truck with 5.7 vortec.
