What ohm pfi injector works with the 7427 ecm from 95 GMC 1TON?

[BigBanks78]

Hi I have a 7427 ecm from a 1995 GMC k3500, 5.7, 4l80e I plan on using in my 78 Regal with 455 and 4l80e. You guys told me to use ford turbo coupe injectors with the 455. I read that they are 11-13 or 18 ohms. I just want to make sure they are the right ohm for the 7427 ecm. I haven't seen any red tops anywhere but do see lots of 11-13 ohm injectors in various # flow rates so I'm assuming that any injector will work at that ohm rating???

What injector would you guys use? I found several 46#, a 52# and some 60# injectors, thinking about getting 60#s but thinking they may be a little big for good idle but I don't know much about injectors so any advice is greatly appreciated!!

Thanks everybody!!! :-]

Those would be "high-Z" injectors, which is what you need.

I seen u have some low z injectors for sale, wanted to make sure before I bugged you about them :-)

Are the different styles like ev1-ev6 better from 1 to another? Going to look for easiest to replace, most common injector type unless there is a BEST for the 7427.

Yeah, those injectors are long gone.

Other than physical fitment differences, I'm not sure what is different between the different series of injectors. I just use what I can afford and what fits with my needs.

Saturated switch vs. peak and hold perhaps. The drivers in the ECU are designed to match injectors they are used with in a specific application.
