your truck will still start moving at lower RPM the stall is just the point when it the torque convertor locks. IIRC its around 1800-2000 on a stock truck.
Too small for my taste. Barely looks lifted. The 37's are just for a limited time, have fun with truck was up high. It will come back down, and run 35's on 20x10's in the summer.

I've been researching some parts for the truck/6L swap. For now, the motor is going in, and staying pretty much original until the winter is over (4 months or so). Then I plan on pulling the motor back out, and adding some maintenance parts, updated/performance parts and then some go fast chit.
As it sits, its a 2002 LQ4 with 75K miles. I am doing intake & exhaust manifold gaskets and bolts, water pump, 3 pulleys, both belts and plugs/coils/wires for now. Mated to stock 4L60E with I6 Trail blazer torque converter (2600-2800 RPM stall).
I am going to slowly start buying parts as money frees up, so it won't be such a huge drop of coin in the spring.
Plans so far are:
-Long Tube Headers W/ ORY (Texas Speed Stainless Steel 1 3/4" with 3" ORY seem well priced)
-3" E-cutout (Texas speed also sells, any other good quality pieces/well priced?)
-New high flow oil pump (vers OEM replacement & porting)
-LS2 timing setup
-new oil pan bolts & gasket
-Efans & 34" Rad
-TSP 228R/112LSA cam, push rods/valve springs. TSP sells a $600 kit for this. How do I know what length push rods I need?
-4L80E trans
-Trans cooler
Things to determine:
-Trans temp gauge: Can I buy a seperate gauge? Don't want to swap in a HD cluster, I have mine setup as wanted.
-NNBS intake manifold: How much work really goes into this swap? Can this be made to work with throttle by cable?
-8.1L fuel injectors: I`ve seen on Ptrucks that they are cheap to put in. What kind of gains do these do? More fuel, more power if tuned? Would it benifit anything with above setup?
-Stall converter: What RPM is best to go with? I do drive highway alot with the truck, and I don't want to loose its "streetable/road trip worythness of the truck. I need a stall that can be fun, but still functional (tow, etc...) 3000 too much? Yank has a 2600HD?
-NNBS intake manifold: How much work really goes into this swap? Can this be made to work with throttle by cable?
NNBS or TBSS intake mani will work. Not too hard of a swap. It can be made to be used on DBC fairly easy. Here is a pretty good how-to. TBSS Intake on 99-02 - PerformanceTrucks.net Forums
Looks like the lq4 has a return less system and your 5.3 was return style. You should be able to swap just the rails (clean them well first) and keep the 6l injectors. That way you will keep the return style fuel rails. I could be wrong but somebody will correct me if I am lol.

I have one of those "which is faster" questions. Basically just becuase my older cousin has to be better than me at everything, and has always thought my truck was a POS. I'd love to shut him up, at least for 5 minutes.
Will my truck be able to beat his in a race now after the 6L swap?
My truck:
-6" lift
-32" Trail grapplers
-3:73 gears, 4x4 (running no front Dshaft right now)
-stock trans W/ 2600-2800 RPM stall)
-LQ4, stock everything, with a BBP 87 octane tune
-cold air intake/no cats/single bullet muffler
His truck:
-2011 Sierra 1500 4x4 crew
-3.42 gears (I think)
-5.3L with K&N CAI & Magnaflow cat back
-levelled with 265/70/17 Duratracs
Thoughs? I think I should be able to take him now. Hope so anyways

How do you disconnect the rail from the crossover tube?
And to anyone who has done a 6L swap, and used stock headers. Did you have to leave off the manifolds when installing into truck? To get motor mount bolts in? Or can I bolt the manifolds to the motor, then drop it into truck?

Like Ryan said, leave the crossover...the fuel line comes off the crossover/fuel rail tho.
you nee one of these to remove the flexible line from the hardline on the rail/crossover
Like others said, use your rail but keep the 6L injectors. Id remove the manifolds since Id install new gaskets.
Correct. Swap your 6.0l injectors to your 5.3l rail. Make sure they get a good seal. Vaseline helps :naughty:

That'll be a close race. Those new 5.3ls make more power than your 6.0l. Once you're cammed with headers you should win. I'd wax newer silverados, tundras, and f150s all day in mine.
The crossover just pulls out I think. Make sure not to damage your fuel pressure regulator.
I took all manifolds off.
ok, ive never pulled an engine out of a NBS but Ive done LTs and head swaps....looks as if the steering shaft is in the way of pulling the engine out with manifolds, but I guess you could remove it? idk. Id slap them on once the engine is in there, would be one less thing to get in the way
I don't think it'll go in easy with manifolds on.
I've dropped a motor in with the entire exhaust system still in the truck, just with LT's splayed to the sides just a bit. Probably not a great idea putting stress on the exhaust like that, but we did it.
Just make SURE you do not bump the motor into the torque converter when you're rocking it down onto the mounts. You can smash the pump very easy doing that.
And your 60e should be just fine on WOT upshifts. It's the random stomped heavy throttle downshifts that will kill it fast.
5.3's and 6.0's had same fuel systems, but just differed between years. Stick with the return style. I'm surprised by your 6.0 having returnless style fuel system; it appears to be slighly older with the tall style oil pressure sending unit. Looks super clean though! Nice score on that motor.
How oily were the intake runners?
I'd get a pcv catch-can on there asap after you get motor in. You'll be amazed by how much blow by you dump out from it regularly.
Does your cousin's 2011 have the 6spd? I can never remember what years they became standard...
It was a 2002 but has return less fuel system??? dafuq, that doesn't make any sense. What was the lq4 out of?
Manual downshift is a controversial topic, but that is what I do. My Silverado has a b&m ratchet shifter installed in the console so I'm always rowing it wishing I could get a t56 with autotrac!
Many shift kits will hold the gear in 1 and 2, but shift normal in D.
