I have a 90 Camaro Iroc-z with a 350. I am replacing the injectors. I originally bought 19lb injectors and found out those were the wrong ones. Before I drop $300 bucks on new ones, I want to make sure that the 21lb injectors are the correct injectors that go in my camaro or if 23lb injectors will work. I have headers, 3in flowmaster exhaust, and the motor is bored 30 over. Can anyone verify?? Thanks in advance.

 

Stock FI for a 350 are 22#.

 

That's what I thought but everywhere I look there are only 21lb or 23lb injectors for sale, no 22lb. Does anyone sell 22lb injectors?

 

1 lb more or less is not going to make any difference. The ECM is going to adjust the pulse duration to get the proper air/fuel mixture.

 

Do a search, they are out there.
