I am planning of building my stock 302 on my 91 GT. I was planning of getting this kit and the Trick Flow upper end kit with Track Heat intake. What size injectors and fuel pump would fit best and is this all going to be safe on my stock block?
That list of mods is going to require a dyno tune. I would recommend contacting who you plan to do the tune, and see what injectors they prefer to tune with. You will be operating towards the limits of the factory block, but if driven sensibly with a safe tune, you should be fine.
