Nice looking burb! Did the PO install the 8.1L? 8.1’s didn’t appear in Suburbans until 2000 on the newer GMT800 platform. This GMT400 Burb should have a Vortec 7.4L.

I was thinking the same thing, lets get some under hood shots of this beauty.

Didnt take long to get the sweet SBD sticker on it! Nice mall crawler. Need some pics on a parking block!

Cool, and X3 on the under hood shots...

I,like it.

I'd rock the sh*t out of that, nice find.

Curious about the motor also, I.had a '99 2500 and it was a 7.4 I'm pretty sure it was the last year for them.o

Nope I had an '00 k3500 "obs" and it had a vortec 454.

It could very well depend on the year it was made and so on. Late year models such as my 90 Sub, come up as 91s. Even though it was produced in September 90 in Flint Michigan. But, either way a 99 shouldnt (doesnt mean it doesnt) have a 8.1.

Poor guy come here to show us his sweet new Suburban score and us nerds fill up two pages taking about what engine it doesn’t have

I worked at GM in Detroit and was on a rotational position through the GM truck vehicle allocation group in 1999 and can I can guarantee you no GMT400 platform Suburban left the factory an L18 8.1L in it. The only GMT400 rig to get an 8.1L was the 2001 and 2002 3500-HD trucks. Those were the odd ball 2wd straight frame rail trucks with the leaf sprung I-beam front axles. The first Burbs to get the 8.1L were the GMT800 platform Suburban’s. Although there were two different body styles being built in the 2000 model year Suburban’s….trucks too. That creates a lot of confusion.

All vehicles produced by all manufacturers in september are classified as the next model year.

Nah, it doesn't work like that these days. In the old days that was pretty accurate but not anymore. With emissions regulation changes being a moving target vehicle model years often follow the engines certified emissions package. For example, Ram just finished up their 2012 model year run of certain diesel trucks about 90 days ago (well into the 2013 calendar year) when the 2012 Cummins engines were used up. The reason is because of emissions changes were 2013 will require SCR, whereas 12 did not so 12 became a big model year run.

All manufacturers do things like that for different reasons. The company I work for built 2010 chassis with 2009 L18 engines all the way to the end of the 2011 calendar year but they still had 2010 VIN’s because of the L18 emissions certification. The old days of saying a vehicle built after Sept of one year automatically makes it the next model year are gone and have been gone for years. The only true way to identify a model year is by the 10 digit of a VIN. The 10th digit is the year the manufacturer certified the vehicle.

VIN years are easy to read…..for 10 years VINs will follow numerical order…. 1(2001), 2 (2002), 2 (2003), etc….. Then at the end of that decade they will switch to alphabetical order for 10 years….A (2010), B (2011), C (2012), etc…. then the back to numerical for 10 years, etc…. That is a SAE standard.

The 8th digit of the VIN is the engine, which the Suburban in question here will have “J” = L29 7.4L

Well to end this I cleaned off the tag in the engine bay and it has the 7.4. I just heard it has the big block and assumed it was 8.1. Regardless it will still trailer my Blazer around with ease. I will get some more pics real soon.

I use the 7.4 Vortec minus the EFI but added the TBI to it with a carb intake and it runs great. Good running motor (poor fuel economy ) but a good motor. Im planning on installing a cam and all that neat crap in mine as soon as I cut out the factory crossmember so I can drop the oil pan.

Yep, nothing wrong with L29 Vortec 7.4L engines!
