My friend just got his super charger put on his 2004 SS silverado and replaced his injectors with 43# ones. he said i could have them if i wanted them, not sure if they will work for me in my 91 z28 5.7L, they are rated at 22.1 lbs/hr @ 43.5psi. they are the delphi multec II design, not the ****ty original multecs, they would be perfect, but the problem i am having is they are the ev6 short style injectors. they measure exactly 2 inches from o-ring to o-ring. the original injectors measure 3 inches from o-ring to o-ring. so they are one inch shorter, i know you can use a little bit shorter injectors, but one inch shorter seems a bit too much. i could grind down the injector bolt holes on the intake a bit, is that too much to grind off though. what do you guys recomend that i do.

 

Sounds to me like they just won't fit from being to small to even consider using. If your fuel rail isn't holding them in you may leak and cause a fire...

 

I'm very certain that you cant use 1" shorter injectors.

 

hmmm... With shorter injectors, just maybe they can be worked with our rails along with NOS direct port injection( think thats what its called) that they sell in a universal kit and a kit for mustangs.

 

You can get a set of 8 22 lb injectors off ebay for $20, why bother messing around with the 1" too short multec IIs?

 

multec II's are better than the multec I's. i have been looking on ebay for them, but can only find the multec I's. i refuse to use them, they are just junk. the pre-multec injecors are fine, but i cant find any right now, and i have these multec II injectors that only have 500 miles on them, so i just wanted to see if i could get them to work.
