I am working towards a 408. I am still a relatively stock 6.0 I need injectors now due to a misfire. Which injectors are plug and play with a good known value for tuning
?? I was thinking 42-44 range

 

The ever popular 42 lb drop in 8.1 marine injectors are the easiest to tune . I got rid of those and got some FIC 75 lb ones and their data was pretty close as well.

 

I would go with either the Delphi 44lb marines or Siemens Deka 60lb injectors. They are used in tons of vehicles and there's a wealth of data for them. You would have to splice pigtails but thats nbd. You're smart for looking into this ahead of time, most people never think of it and it can make for big headaches whin tuning comes around, especially with custom built injectors
