    Cam Help

    If you are handy with a wrench, you shouldn't have any problems. The cam is easy. It's straight forward and the only special tool you will need is for the valve springs. Just remember to use the dowels to hold up the lifters. There is a great link for a cam swap on ls1tech. You will most...

    Cam Swap in 03' Yukon

    If it's for an '03 you don't have to remove the intake, that's misinformation. If it's for that '89 for your handle...yes you do!

    Yes, you will want to replace the pushrods. The springs are going to depend of the cam you choose

    The GT2-3 is a great cam for FI, don't get me wrong, but it idles like a stocker (stealth), which is why it wasn't recommended, and without FI the gains are very minimal. The vinci trucker cam is the same way,, a small amount of lope, better NA. You need to decide if you want lope or if you...

    Yes GT4 is 3.73. I would still go with the EPP blower cam and a 3200 stall.

    Absolutely, also with that cam you will want at the very least 3.73 gears. You need to find out your gear ratio, if you don't have the tow package on your truck, I suspect you have 3.42's. The gear code will be in the glove box on the list of RPO codes. Look for a code starting with a "G" and...

    running from the popo stories lets hear them!

    Being a LEO, I will tell you this... you have alot better chance of the officer cutting you a break if you don't run. The minute you break the PoP rule, you are done for. Not the smartest move on you, and your buddies, part.

    03 5.3L; Upgraded lifters?

    You already have hydraulic roller lifters. My guess is that you have cold start knock CSK, which is normal.

    Used Whipple kit for $1200??

    If you are not mechanically inclined, I would stay away from the whipple. Like Bro said "With a few changes to my whipple" 1. Their fuel management sucks and has to be deleted and tuned to get it running properly. 2. They generate alot of heat. Just my 2 cents.

    That cam is fairly wild 239/243 @.050, but it's your dollar. You would need a 3500-4k converter with it. I still recommend the EPP FI cam w/a 3200 converter. Did you ever find out your gear ratio?

    What would you change on lq4

    That would work well with a 2600-2800 converter.

    Changing Water Pump

    To make the job easier you should remove the fan whether you need to or not. You will have to put it on the new pump anyway. I used a pipe wrench, along with a crescent wrench, to get mine off. Remove the fan shrouds and radiator hoses going to the pump. Now get a 10mm socket w/extension...

    Which truck do you have? The only place I have found qd's is for the feed and return lines at the intake.

    LQ4 replacement heads

    Since you have to stay smog... I would go with a corvette z06 cam and springs (you will need new longer pushrods too) then save for a turbo or supercharger kit. The z06 will give you a nice boost over stock and it is a proven cam for FI.

    Good deal? Help me: 22s and full break/rotor set front+back

    yes, the BRAKES are the same and will fit. That's a damn good price btw. What size are the rotors?

    Turbo or supercharger... 4.8l needs power

    You should start saving for a replacement tranny now. It will not last long behind a supercharger.

    If it only does it when the engine is cold, I would suspect the intake gaskets.

    LQ4 replacement heads

    You could, and it would be a nice bump in compression. However they will not flow as well as a set of 317's ( stock LQ 4/9). Look for a set of 317's and have them milled .040" or you can opt for a set of 243's, but that will set you back more. Really it boils down to what you want out of your...
