I don't know why all my pics are sideways.

While driving back into town today the truck in next land tam over a huge L shaped piece of metal and it managed to fly into the side of my truck. It went through the paint and slightly dented the cab and also scratched minor parts of the bed (behind the cab...).

 

I'll call the insurance since our premium is $500 iirc, and fixing this will surely go over. FML.

And it may be called an L33, but you may in fact be getting a LM4. The LM4 is the aluminum 5.3 identical to its iron LM7 counterpart. The LM4 was in the Trailblazer, Rainier, Envoy, and SSR

 

 

They have the vehicle listed that it comes out of along with the Vin# for it. The one I'm leaning toward is out of an 05 Silverado with this VIN: 1GCEK19B55E136371

 

Is there a way of identifying that it's an L33 from anything on the engine block?

Casting numbers i am not sure. It will be aluminum and say 5.3L. The iron blocks say 4.8/5.3. I dont know the block differences in the LM4 and L33

Okay. I'll try a google search, see if I can find any information...

 

 

EDIT: Here's a link with some info: http://www.performancetrucks.net/forums/gmt-800-older-gm-general-discussion-130/how-identify-l33-498775/

 

A few things I took from it to identify,

 

- 799/243 Heads

- Knock Sensors are only found in the engine valley under the intake manifold

- Aluminum Block

The only difference in LM4 and L33 visually are the head casting numbers

Ill let ya know Ryan, but definitely will be looking to go within the first few weeks of opening to get my 12 second timeslip in this pig.

 

Opening day for Lucas Oil Raceway�s dragstrip will be the first of nearly 25 scheduled Wild Wednesday Test & Tune events beginning April 1. Wild Wednesday presented by IndyRPM offers open time trials for both street legal cars and slick tire race cars.

Left yesterday morning for a weekend ski trip with a bunch of friends. Tonight got cut short for a few of us because my buddy messed up his wrist. Putting lots of miles on the truck this weekend!

The eighth digit of my Sierra's VIN is “B” which identifies it as an L33.

 

The L33: Aluminum engine block, new cylinder heads, flat-top pistons, and a high-lift cam – Increased torque and 315 horsepower..

My hood won't shut... did this last time it got really cold... I'm not happy.

 

I'm sorry, Sarah. We all must cross that bridge sooner or later in life as we get older, things just stop working or don't work as well as they did in years past. But have faith, we are all here to help and support one another! :tumbleweed:

Are the knock sensors only under the intake manifold on the LM4 too? I guess I'll just have to look at the casting numbers on the heads.

Yep, you're correct. I was just hoping there was something on the block itself to confirm that it is an L33. Hopefully the head casting numbers will be enough.

    • I would have to read back to get a better picture in my mind of some of the other comments and what they were using for a driving scenario they based the fuel mileage off of. That is why the fuel mileage conversation is extremely difficult to make fair comparisons from. If I was to be living in town and only driving around town, light to light and some longer stretches that doesn't have a light every block, and the usual stop at a grocery store and the bank and so on and so forth, my fuel mileage even during the summer time would be so bad with my truck I don't even want to know how bad it would be !. Then add in winter time and idling to warm it up to clear the windows and driving through snowy streets etc, large heavy trucks with gas engines have NEVER been worth crap for fuel mileage and why some little pot licker of a car with wheelbarrow tires and a 1300 cc four cylinder non turbo engine was the ticket to using a mere fraction of the fuel over a full size pickup.    By the way my truck has the 34" tires as its a HC but not the BFG KO3 tires ( that was an option for my truck but the sales guy couldn't figure out what the tires actually were so that never got on the order until it was too late to change the truck order ). So what fuel mileage your getting actually sounds good for "town driving" and with my truck when I go to town the fuel mileage keeps increasing as I get closer to town because it takes quite a while to get the driveline oils warmed up ( and why it always shows better fuel mileage on the return trip from town because its already warmed up ) but once I am in town that fuel mileage average just keeps dropping the more I mess around town and then has to recover back to something reasonable again by the time I get home for an over all average.    I'd be curious what your sticker says for the factory weight of your truck, mine is close around that 7700 lb due to the options it has. But anyway the long and short is, vehicle weight, higher rolling resistance heavy tires and a hefty driveline and a relatively large gas engine make for crap fuel mileage in stop and go scenarios, all one can do is drive it easy off the line at each stop and as my dad had said over the years, drive like a raw egg is under your foot and that's the best one can do. Years back with a carbed engine and if the carb was getting a bit out of tune etc as would the ignition system, the fuel mileage on pickups with larger engines was just awful compared to what your getting. We pay the fuel price penalty for driving HD trucks over some little vehicle, that is the reality. 
    • We had two Toyota’s with that engine in the mid 80s. We had 50 gallon fuel tanks, a toolbox full of tools, an air compressor and assorted parts for our equipment. We beat those up and down pipeline ROWs until we started buying diesel trucks. Then they became parts runners and first vehicles for our teenagers first cars. Our shop Forman wrecked them both two years apart when we hired him out of high school as an apprentice. Good thing he’s an excellent mechanic. It took awhile before he could be called a good driver.
    • I have a 2025 GMC Canyon Denali.   On a trip recently the engine failed.  The dealership diagnosed a bent valve and says there is a service bulletin that indicates to 'relace the engine'.  The truck only has about 14K miles and is under warranty.   The failure occurred 5/11/2026.   So far I have worked with GM Customer Assistance and Roadside Assistance.  Evidently no engines are available and nobody will offer a date when a new one will be.   Coming up on two months with no repair or timeline and no loaner from the dealership.   GMC Customer Assistance is 'ghosting' me and keeps closing the cases I've opened with no resolution.   Hoping someone can help me on how to escalate this issue.
