    I'm running a simular and ported heads on stock injectors in my 04 goat if that helps....i still have lots of room to play, I'd have to go back and check my logs, but I think I was maxing out around 74%

    The Lucas 48lb LS1 style injectors are a great injector and will support what you're doing, and a lot more in the future.
    Keep in mind, fuel rails and a better fuel pump will bring the injector duty cycle down as well.

    if you stay in the 224 range you might be fine on the stockers. I would check the duty cycle though after you get it up and running to make sure.

    As mentioned above, stockers should be fine unless you are gonna spray. I had LS6 stage 2.5s and MS3 cam (237/242 dur., .603/.609 lift, 113 LSA), no spray, on stock injectors with absolutely no problems.

    did you ever check your injector duty cycle? I would think that would really be pushing it on 26#ers.

    I had the same setup (01, bigger inejctors) with true duals make 432rwhp last week and maxed out his 28s at the end.

    I made 420 and pulled all the way to 6500 smoothly, never checked the duty cycle though. I did however switch to 42 lb'ers when I got the FAST 90.
