I need to change my stock injectors, the car has a blower and cam. What size should I get? Also what would be involved in bigger sized injectors. I also want to remove my A/C, could I just disconnect it and get a shorter belt or would i need to get a pulley to takes its place? Thanks for all the help

Go w/ 42's. That's what I'm moving up to. Currently have 30's.

What would be involved though, would I need a bigger fuel pump? Or can I just use the stock fuel pump. Since my car isnt MAF does the map sensor need to be calibrated?

How much boost are you running. I just put an SC on my car, with a 5 psi Vortech unit, and I went with a 190 lph fuel pump. Do you have a higher volume fuel pump now?

my 89 5.0 w/ 8 lb powerdyne stock cam has only 24 lb injectors... If you're doing only around 5-6 lbs, I would recommend 24 lb injectors... If you're going from 7-10 lbs, I would recommend a set of 36 lb... You'll really need an adjustable fpr to make this work right, but going a little bit bigger than what you ened is a good thing. That way when you bolt on a big set of heads, or turn up the boost with some pulleys, you're fuel willl be waiting to match it.
