    'fraid not, those never had mid-90s LT1s in them.

    Stall converter

    The cam did not make breaking the tires loose any easier, did it? (Taller tires didn't help either.) A higher stall-RpM will strain the transmission, even when you're not towing, even with an ATF cooler upgrade, moreso when you're towing. You want more power UNDER 3000RpM. A higher stall-RpM...

    Gear ratio

    Put 4.10 axle assemblies on your '05 Yukon (likely cheaper than regearing the axles internally). From having tuned many LT1 B- & D-sedans & wagons with 2.56, 2.93, 3.08, & 3.42 (& 3.73 for the more enthusiastic enthusiasts, 4.10 for a few hardcores), 3.42 & 3.73 were the axle gears that made...

    Repay the debt by giving the vehicle back to him for $1 @ 300,001 miles.

    Your opinion? Parking lights.

    If you're asking for an opinion about aesthetics, there is NO accounting for taste; can never be sure 'your' tastes are even really 'yours'. Functionally, amber works better in bad weather, & tires night vision more slowly. Prefer high beams & low beams 4500K-5000K, everything else 4500 or amber-er.

    Gear selector display dim

    cough What does one do if they have a 2002? Looks like Digital Dash Solutions has none for prior to 2003.

    FW_Z71Burb's 2002 Suburban Z71

    And for the DuraMax (& DuraMedium & DuraMini, as well as other turbodiesels), there's "Valvoline Premium Blue Restore", which is pretty tough to find under $75 a gallon, if I'm not mistaken.

    FW_Z71Burb's 2002 Suburban Z71

    Switched to Valvoline Restore & Protect 5w30, winter of 2025. After 3 oil changes with this stuff, my mechanic asked me if I'd bought a new dipstick, had trouble believing it was the same old dipstick. Wish I'd switched winter of '24 when V R&P first debuted. No longer see a point in using any...

    Tire sizes

    I'd go with 265/75R16 (regardless of load rating), I prefer fatter taller tires.

    Tire sizes

    I wouldn't go wider than a 16"x8.5" wheel, but that's me. If they are P265/70R16, NOT LT265/70R16, then 16"x9.0" is a small sacrifice to make for a deeper dish. Just don't carry more than it says on your door, in your bed.

    Southern California 2003 Silverado SS

    An aluminum-head LQ4 is pretty much an LQ9, except with dished pistons & a 9.4:1 scr, vs the LQ9's flat top pistons & a 10.1:1 scr. Interesting fact: After '01, LQ4 LQ9 & LS1 all share the same replacement cam part number: 12561721. Oversimplifying a bit: an LQ9 is basically a cheaper LS1 for...

    old retired dude

    Pop open the glovebox. GU5 = 3.23 GU6 = 3.42 GT4 = 3.73 GT5 = 4.10 4.10'd be best for metro/urban & towing MpGs, as well as the 4L60E's longevity between rebuilds.

    Miklo's 2001 Silverado 2500HD Build Thread

    Let us know if your ATF temps change after you change grilles.

    It's happening

    For $1600: * if it throws (a) trouble code(s), it should provide the code(s) to the driver immediately upon request, and include real-time data visualization and recording for diagnostic expediency, without needing a separate device or mechanic *should provide 'historically inspired' DIC options...

    EVAP P0446

    I'll be sure to remember to ask you why, then crack open a Bud Dry, if only because I don't remember when you didn't have a good answer as to why. Also, I thought whaanmbulances have fully functional evap systems. ;)

    EVAP P0446

    I actually agree, but if you don't EXPLAIN WHY, you sound more like you're ordering a stranger around, than sharing knowledge. Unfortunately I don't know enough about why to be more helpful, but I thought it had something to do with preventing the tank from ballooning?
