Looked like fun while it lasted. If you want some good advise that will save you a ton of money, build it big and back it down about 20% and enjoy it. Gets old as hell breaking motors and trannies. A 1000 hp engine will not last very long if you run it that way all the time and sure as hell can't drive it on the street. You injectors are big enough as well. If you get much larger the restriction in stock injector bodies will not let them flow any more fuel anyway. Anyone who says they are running 200% over or whatever on stock injector bodies doesn't know what they are talking about. I'm not even sure my 100% over are flowing that much fuel at WOT. Rail pressure holds but who knows for sure what they are flowing without a bench test that can duplicate the actual performance in the engine? Good luck on your build. At minimum I'd put in a girdle on the bottom end, and stud everything that can be studded. That crank will walk if you don't. Good luck.
