I'm not entirely sure...i would look for the "neon injector swap" thread with a bunch of pages but IIRC they do work with the v8s

There is a lot of information on this swap but I didn't find a straight answer on the part numbers for the v8's either. My friend has done this so I'll email him.

I was told for the V8 to use 24# bosch, Ford racing, or accel injectors for early 90's 5.0's. 4-hole pintle, direct swap.

I recently swapped the injectors in my 98 4 liter GC with the 703 injectors from the 96 Stratus. I have to say this was a cheap easy upgrade and the benefits I see so far are amazing. I had 3 leaky injectors so i has starting issues. The truck sounds like a totally different vehicle, its idle is amazing and the throttle response is also much better. I'm doing a test on the fuel economy difference now and will post the difference when my tank gets to empty. I heard I should see a 20 mile increase per tank so here's hoping. It has to be better since the gas is now being atomized so much better with the 4 hole injectors over the 1 hole ones the truck came with.

My buddy who has a modded 5.2 says that he got his injectors from a 1999 2.0 dodge neon.

I believe you can get them from the 4.6 crown vics and mustangs as well. People choose this route because then you're able to get them all off of one car. If you go the Dodge Neon route, you have to use them from 2 separate cars since they are 4 cylinders. I haven't done it yet, but its on my list of soon-to-come mods.

Here is the part number to 1 of the bosch injectors. I think its the Dodge Neon one - 0280155703

Check out this comparison video:
