I'm looking to try some slightly larger injectors on my 383 SuperRam. Has anyone got any experience with the Delphi injectors? Racetronix pushes them as a lot better, but I don't know. Hence the question. Looking for other possible vendors as well. I'm currently running the LS1 28# injectors.

Also - aren't all Ford 30# injectors supposed to be RED? I've seen some that look to be light gray or white colored that were labeled as "Ford Racing" injectors, which I thought meant SVO....

Appreciate any and all replies to this!

We use the 37 and 42lb Delphi Injectors on many LS1 applications. They've worked well everytime we used them. The 28lb LS1 injector your currently using should be good for around 400-420rwhp at 45-50psi fuel pressure. All 30lb Motorsport injectors I've seen have been red tops. Good luck.

Thanks for the info David - I really appreciate it!!!!

Do you think the Delphi style are any better than the LS1 injectors? Just curious....
