    Researched GM LS / Vortec heads. Ignored LS1 LQ4 & LQ9 heads, LS9 & LSA heads, LS7 heads. Two types of holy heads ('holy' is shorter for 'cathedral' than anything else I could think of): 12559862 / 12561706!: . . '99-up 4.8L / 5.3L: 61.15cc combustion, 200cc holy in- port, 70cc oval ex- port...

    My '02 Tahoe L59 revs WAY too high on cold start ups. Anyone got any ideas?

    Whenever I start my '02 Tahoe L59 cold (6 hrs cooldown or more), the engine briefly revs up over 1600RpM. This morning, it wasn't even freezing outside, yet it revved itself to 2000RpM for a few seconds before settling down to 1000RpM. The first five minutes, I REALLY gotta lean on the brake, or...

    Is better on-road handling possible without losing Z71's off-road capability?

    No longer interested in either lowering or raising it. Recently did GMT900 front brake upgrade. The braking performance improvement has reduced my fear of driving it considerably. However, the thought of emergency lane changes still make me somewhere between nervous and uncomfortable. (Majority...

    '02 Tahoe with '10 Tahoe PPV front brake upgrade

    Wasted a year of my life dumb with '02 OE front brake kit; driving around afraid, braking early / cowardly, missing Caprice 9C1 / PPV brakes like dear ol' pals. Is a life lived without any regret really fully lived? Still, every regret sucks. I regret settling. Haven't even finished breaking...

    Husky, vs Husky, vs ...

    Recently read too many threads preferring Husky interior mats over WeatherTech. Problem is, WHICH Husky Floor Mats? Husky makes FIVE very different versions. Uni-Fit $70 for 2 front AND 2 back, cut-to-fit. Far and away the big bang for the buck, but obviously not the best. Heavy Duty $90 for 2...

    How simple or complicated is it to add an ATF temp gauge to an '02 Z71 gauge cluster?

    Just read this post. I would REALLY like to have an ATF temp gauge added to my 2002 Tahoe Z71's cluster (although it's not NEEDED, I prefer not to settle). I do NOT want to do this myself. Who'd be so kind as to accept some of my money and do this for me? Do I need to provide them with my...

    GMT821 Z71 vs Special Service Vehicle: Similarities? Differences?

    Curious about what '00 - '06 Z71 has in common with SSV, as well as how they differ. Wondering if there are suspension / steering upgrades from SSV that can be applied to my Z71, without lifting my Z71?

    Part 1: center console delete.

    Gave many driving lessons in a '94 Caprice wagon with front sofa. A solid single front seat that only moved fore or aft. (Obviously a benchable driver's seat with fold-down center seatback that doubles as armrest with storage, is preferred.) That wagon got me so accustomed to lacking a center...

    GMT900 front brake upgrade for my GMT821 ... what ELSE do I need?

    Unless convinced otherwise, GMTK2xx or GMTT1xx front brake upgrades seem like diminishing returns vs GMT900. Drove a 2012 Yukon XL for 5 years as a livery vehicle in NY / NJ / CT / PA, assertively if not quite enthusiastically. Carefully chosen front brake pads kept me from investing in any...

    LargER L59 V8 oil filter part number

    Typically I mix'n'match whichever brand motor oil happens to be cheapest, but only if it's 0W30. Yday my Tahoe told me to 'Change Engine Oil', just shy of 4,000 miles. Next time I'll change @ 3500 miles. I am vehemently against using a tiny oil filter. I'd much prefer to use one with extra oil...

    Poor man's rear camera alternative, an exterior mirror ...

    Pretty much been forced to stop inside every car parts store and car wash, to look for what I can only describe as 'a mirror attached to the rear window glass that functions like a poor man's backup camera that needs no electrical power' It's an unwieldy search term that makes it impossible to...

    Don't like GMT800 side view mirrors. What about GMT400, or GMTK2?

    Won't be towing, no need for tall winged / telescoping side mirrors. (If I tow ONCE, I'll buy the ones that strap-on to the doors and resell them after.) Prefer '90s GMT side view mirrors, as well as rectangular ones on GMTK2 trucks / SUVs from a few years ago. In case it matters, my side view...

    What's the SHORTEST tire GM fitted to 4-door Grand Blazers / Tahoes between '91 & '07?

    Specifically, what are smallest diameters GM ever OE fitted for 4-door Tahoes between 1991 & 2007 (GMT400 & GMT800)? (Please ignore 2-door Blazers.) My Z71 presently wears 255/70R18 (32.05") - thank previous owner for 18" wheels. Want to lower it a wee lil bit, but not with shorter springs at...

    Ran out of Caprice 9C1-LT1s, replaced with an old Tahoe

    Those who know the ISSF well may also be familiar with me. Don't quite love my '02 Tahoe Z71 yet, but I already respect it a whole lot. Looking forward to the ability to tune GMT800s.
