42lb Lighting Fuel Injectors

Will 42lb Lighting Fuel Injectors fit a '90 Coupe? I have a blown 331 and am looking for some bigger injectors. The injectors that I can get are Green...

Yeah they will work just fine. You do need to get your mass air meter calibrated for the injectors. What do you have for injectors, and mass air meter now? I would go to a pro-m 80mm for those ditch the fmu if still in use and get a good dyno tune.

I currently have 30 lb injectors and I am not sure what size Mass Air, as it was with the car when I bought it...
