Changing out rusted injectors

Where is a good place to buy/ rebuild the injectors??..heres my story
A 94 caprice 350, LT1 went into my elky 10 yrs ago, got it started, ran it for a couple weeks and then shut it down (project car) up until 2 yrs ago... a couple weeks ago I was ready to fire up my rebuilt LT1 after the 2yrs of rebuilding it. Found out after troubleshooting the fuel system that the injectors valve springs were rusted and corroded (took them to a local shop) Any suggestions on were to go for decently priced new/ reman. injectors?


What I do know:
The local shop guy that checked out the injectors will tell me today when I go pick them up when I can get some from the mainland , he said around here they are too expensive. He said A/C delco and Bosch were good.
Yes, I got 43.5 PSI at the rails and I get the pulse readings from all 8 injector connectors ...Thanks

you could also try Cruzin Performance

I have used them twice to clean/rebuild/test my injectors. IIRC it is about $12-$15 per for the service. They send a B/A flow chart showing results

IDK if your "rusted springs" can be replaced but assume they can...might be worth a email to them

if getting replacements you just want them to be the same as stock ones you have or you will need a PCM adjustment

Ok, I'll check them out too. My local shop guy said that the OEM Multec injectors weren't all that great. The Bosch injectors according to fuelinj and fiveo are for stock unmodified PCM's

hi all, little update.. I got the Bosch Gen III from fuelinjection..so far in the last couple weeks the engine starts right up and so far they perform great at idle and revving. The truck isn't road worthy yet still garage/driveway bound. really knowledgeable people and got them at a good price
