    Finally some numbers.



    seems a little low?

    lower hp/tq numbers were before tuning it on the dyno

    it was about 90 degrees in the shop so that could have played a part.

    for those who dont know my set up:

    383 ci 10.5:1 cr
    243 heads (stock)
    220/220 .551/.551 114LSA
    90mm intake and tb
    Ebay lt headers no cats 3in cat back
    E-fans
    running through 4wd, 4l60e, tb stall, 3.73 gears, and 33in tires

    what do y'all think?

    With your 4x4, small cam, 3.73s, and 33s, I'm not surprised at those results. You have some nice TQ. I wouldn't be upset with those results. All that matters is that you are happy with the truck and how it runs. I know you wanted something streetable and that's what you got.

    I am definitely happy with how it runs and jumps when I get on it. I guess I was just surprised how low the numbers were. My tuner also commented on the nice torque curve.

    I'd be a little upset with those numbers i figured a 383 would do better than that at least 400 range.
