I purchased 4 racetronix 42lb 440cc injectors used, and i just saw that at the end of one of them where the honey comb triangle is with 3 holes the holes are like stripped out so its like one big hole. SUXXXXX My question is would it be ok if i used 1 440cc 42lb injector for a ford lightning? It is high impedance. Thanks I appreciate all the help!

If you do, send all of them for a cleaning and flow balance first. if they were a matched set i wouldn't worry about it, but since they are not, you should have themflow-balanced by rc engineering.
