Will i be able to use a dry kit on my 94 lt1? And how big of a shot can the stock injectors handle?

 

The most popular dry setup for the LT1 is the NOS 5176. Good for 125-150HP. But you would need to swap out the injectors, not for larger ones, but for a different type. The dry kit increases fuel flow through the injectors (when you spray) by boosting the fuel pressure to 85-90psi. The stock RP ball and seat injectors will not operate reliably at these pressures, and need to be replaced with a pintle type injector (Bosch, Denso, Ford SVO/FMS, etc.).

I ran the 5176 for 5 years with no problems, using Ford/Denso 24# injectors and NGK TR6 plugs.
