fuel injector woes

i just dropped off my fuel injectors at the local injection shop and have been informed that both my primary injectors are showing 19 ohms resistance which apparently is too much. so now i need to replace these injectors but the injection shop can even locate replacements! jesus is there no luck with this car?
are there any other injectors i can swap in that will work properly? lady called me asking me the vin number to make sure she gets me the right injectors either low or high impedence.

No, not without computer tuning and significant modifications. You could put them in your secondary slots but then you'd still be stuck with shitty primaries.

The 86-87 low impedance 460 injectors are not exactly hard to find.

I have a clean set of 89-91 high impedance 460 injectors that could work for you. Here are the mods that would need to be done for you to utilize them on your engine:

-change injector connectors to 89-91 style

-locate injector resistor pack under air filter box, unplug it. Cut off oval plug on harness-side, solder all 5 wires together and insulate well.
