putting in a forged 347 this weekend and cant get it tuned until atleast monday. I have a set of 37lb an hour injectors for it, and heard you're not supposed to run a bigger injector unless its tuned. Is it alright to run this setup of my stock injectors? its got a 232/236 cam. stage 2.5 ls6 heads, fast 90/92? my computer is tuned now for a tr 230 cam w/ ls6 intake and is running quite rich.

yes but keep it under 4K rpm and that is for break in time only, avoid driving untill tuned.

Do not put your new injectors in until you get it tuned for them. You risk the chance of washing down a brand new engine, and never getting proper ring seal. Or even worse spinning a bearing because of too much gas in your oil. Your car will run just fine with the stock injectors just drive it normal and do not go wide open.

Just don't drive it, dude. I mean, you can't go a few days without driving it?

Just run it on your stock injectors for now, just dont take it over 5k rpm as you will more than likely max out the injectors.

Just use the stock injectors and drive it as little as possible.
