Short of the story I ended up with the injectors from the 2.8 and the 3.4.
Now which injectors where any good since they had all sat for years without being run. Decided I needed a why to test them since I'm cheap and didn't want to send they all off to be tested.
I designed a circuit using a LM556 dual timer chip and built a box to test the injectors.
I will build an actual test board for doing injectors at a later date. For testing these I simply connected the injector tree from the 2.8 to a fuel pump and filter.
Connected the pump to a battery as well as the tester box and had at it.
Was able to get all the injectors working and measured the flow balance between all of them by measuring the output over a 5 minute period.
The 2.8 injectors flowed 50ML/5 min. the 3.4 injectors flowed 55ML/5 min. at my set pulse rate.
Below is the schematic of the tester used. It can be modified by adding a push buttom switch with debounce to the second half timer to be used as a balance tester in-car.
