L33 info

L33[edit]

The Vortec 5300 L33 (VIN code "B") is an aluminum block version of the LM7, and was referred to as the Vortec 5300 HO in marketing materials. How ever it should be noted that the L33 uses a flat top piston from the 4.8L instead of the standard dish piston found in the LM7. It also uses 799 cylinder heads, which are identical to the 243 casting found on the LS6 and LS2 with the exception to the Corvette spec valve springs, and hollow stem exhaust valves on the 2002-2004 LS6. This combination increased the compression from 9.5:1 to 10.0:1. Also the L33 had a specific camshaft not shared with any other engine, with lobe lift of 7.2 mm, 193 degrees of intake and exhaust duration, and a 116 degree lobe separation angle. As a result power increased by 15 hp (11 kW), to 310 hp (230 kW) and 335 lb·ft (441 N·m). It was only available on extended cab 4WD pickup trucks. Only 25% of trucks made in 2005 had the L33 engine.

L33 applications:
2005–2007 Chevrolet Silverado 1500 4WD
2005–2007 GMC Sierra 1500 4WD

I know what the L33 is I have one in my 67 GTO

TacomaJD · Dec 11, 2014

It was for a reference as to what it came in from the factory. L33 is not considered Vortec Max, although it is a higher output version of the 5.3L

Slap an ls2 cam and springs in it with an ls6 intake and it'll run like a mofo

TacomaJD · Dec 11, 2014

I had an incorrect reference on the trailblazer SS, it has the LS2 6.0L in it. There is also a version of the 6.0L called the L76 that was labeled as Vortec Max. Last year of Vortec Max availability was 2009

Love the 2×4 tail light mounts, maybe Redneck Lights should look into the next fad for fab lighting accessories.

I have a 2005 1500 with the L33. For being a halfton it pulls like a sumbitch. Dad has a 6.0 and I've been wanting to pull the jeep with it to see if theres any difference other than mine will probably get better mileage towing and way better mileage empty. I had a tuner on it and ran even better but I sold it to my brother.
