    MSD ignition 99tahoe...?

    Did you upgrade cam? If so, which would go best with upgraded rockers? While I'm at it, what else should be upgraded...? If I went with bigger rockers, I assume heads would have to come off and sent to machine shop for ***********, or could I do that myself?

    MSD ignition 99tahoe...?

    Which rocked are you recommending? I know they're not hard btw. Just didn't feel like messing with em, but I'll look into them if they will help with gains. Will they increase hp/tq output?

    Gear ratio, RPO code

    Thanks. Finally, a logical explanation to the 5x1.... and I knew the G80 had nothing to do with ratio, it's either a locker or limited slip, I've read that in multiple places. But I remember when I first got the truck I wanted to see if it would grab posi, so I did a burnout and it only did a...

    Gear ratio, RPO code

    Ok, I looked up my RPO codes to find out what gear ratio I have, come to find out I have RPO code GT4: 3.73 gear ratio, happy with that, then it says"DUP with 5 x 1" what does that mean? I've read all over people saying DUP means duplicate, that has to be false, there is no 5X1 code. And if you...

    MSD ignition 99tahoe...?

    And also, I plan on moving to the country in the next year or so, emissions are not needed there in my state. So I'll probably end up running free flowing exhaust. Also my reason for wanting long tubes, hopefully equal length, to help the motor exhale more efficiently. May run a DI/DO muffler...

    MSD ignition 99tahoe...?

    Ok. I have the 6al, planned on getting the msd coil and wires when I did install, and eventually plan on getting a tuner and k&n induction, any suggestions on the tuner? If I ever have to do intake gaskets I plan on upgrading spider as well. How about throttle body spacer? Any other...

    MSD ignition 99tahoe...?

    Hey guys, I have a 99 tahoe 5.7 vortec 4x4, I've been given a MSD ignition 6al by a buddy of mine, was thinking about installing but I have a few questions... would I need to run 93 octane fuel after installing? Would I improve gas mileage at all? What would the hp/torque gains be? Would it be...
