So I am in the market for new, higher performance injectors. I don't want to go too big, but I want a littlemore performance. What size, #, injector would you suggest for a mild bolt on 350. Also, what pressure should the fuel rails be at with your suggested injector. Believe me I have searched but am not really finding what I need. I don't drive it daily, just at the track and around town. Thanks Also, are LT1 injectors direct plug in in our tpi's?

 

Check out FIC,fuel injector connection.A lot of people have bought from them and are happy.They are even on ebay.Send them a message about your mods and they will suggest a size.Depending on your modsyou may not need new injecters unless your old ones are shot.I prolly wouldnt go higher than 24#/hr for a bolt on car

 

If you want plug n Play you need to stick with the stock 22 lb.

 

I found a OEM Standard Ignition 22lb set for sale. They were originally for a vette. Will these make any difference at all over my 19lb ones? Mine work fine as it is, but I am looking for a little more performance.

 

If you are a 350, you should have 22lb in it. A 305 has 19lb.

I bought some stock replacements from John at FIC. I talked to him several times, he test tried a few injectors in a setup he had on his work bench. Even with the bolt-ons I have, he said stock size was fine. I have yet to run these injectors as I am waiting on a local shop to get done with a part.

 

Plus once you do change injectors you will need to have the chip retuned for that size injecter.You`re probably fine with bolt ons with the stock size unless yours are in need of being changed.
