will it be possible to drive my car with the 383 in sig with the stock stall and injectors? Not racing it, just slooooow driving around town to break it in and rack up some miles?

 

Yes its possible, but if its my car i would wait for the tune with bigger injectors. It must be hard letting it sit but its even worse just driving slow with no wot runs. My friend went for a slow breakin drive that took all day so he could race it as soon as possible.

 

I could buy the injectors if needed, but it'd be driveable with a stock stall? That was my main concern.

 

You will be fine with the stock stall speed. However, I would make sure to have the proper injectors and tune for the new setup prior to starting it. If the injector is too small, you risk the chance of running lean. If you install the large injectors without a tne, you will run rich and risk washing of the cylinder walls.

 

Stock stall, you should be fine. The driveability aspect may suffer some, but that is it. But as mentioned, stock injectors and a stock tune is asking for trouble.
