    New L9H, 6.2l engine code in '09 Silverado locator

    was checking the locator and noticed a new engine option on the '09 silverado crew cabs both 2wd and 4x4. It is L9H and reads "L9H, 6.2L, v8, non active fuel mgmt"

    anyone have any inside info, does the "h" stand for hybrid, figured they might only put it in crew cabs b/c there is extra room for a battery pack???

    Couldn't they just re-tune the 6.0L and bolt it to a 6 speed? I really don't see how GM has trouble making this engine competitive with the Tundra. All it needs is a new transmission and a lack of TQ management.

    I can tell you, after racing my friends CrewMax Tundra with the L33, the main draw back of the Silverado is the transmission. As we started from a 30kph roll, I pulled a head of him until my truck shifted second gear and fell flat on its face. He reelled me in and caught me in no time....

    The 6.2 is better than the 6.0... on the Corvette the 6.0 met Tier II / Bin 5 emission regs (aka the dirtiest "window" allowed under current legislation) but the 6.2 makes Tier II / Bin 4 which is much cleaner.

    The 6.2 option in the Silverado is the same engine and tranny option as the Sierra Denali. This IS essentially Chevy's version of the Denali. They will be nearly identical in equipment. This info has been avail for quite a while on the GM ordering guides. This is also not the Hybrid.

    You probably would have gotten beat worse from a dead stop. The torque management really hurts the performance of a great engine lineup. Hopefully the new six speeds will be strong enough so they don't have torque management. I think the reason they have TM is because the 4 speed can't handle the power? Does anyone know?
    Hope the 6.2 is available in an extended cab as well as I perfer bed space over a back seat. I also don't care if it has the active fuel management. Makes the trucks sound horrible. Sounds like a 2009 Sierra may be in my future plans if this is true...

    Believe me man, I knew what I was doing when I picked what speed we raced from! Haha, It was awsome though because when we both stomped on it, my truck actually pulled ahead, and then his truck shifted second gear while I was still in first, I pulled further ahead. It wasn't until about 90km/h(raced from 30) that he started catching up again. I wonder what would have happened if my truck had a 6 speed, because I know his truck has more power/tq, but the Silverado is lighter.

    It'll be awesome if the Silverado comes with the 6.2L 6 speed and with the same power as the Denali, but won't this overshadow GMC's King of the Hill Truck? I mean I thought the whole reason the GMC had this engine/tranny combo was to offer a unique package. If Silverados are now stuffed with this powerplant that can be had cheaper than the Denali who the hell is gonna buy one?

    You got that right, that TQ management severely hinders performance. I raced an L33 Silvy in my S-10 from a dig and I had him by a nose up to about 90kmh before he passed me. I would be kinda embarrassed if my HO V8 couldn't smoke an antiquated 4.3L.

    Yeah but a Silvy weighs a lot more And maybe the Silverado wasn't actually racing

    You should have kept going.... his Turda would have probably thrown a camshaft.

    GM definitely needs to get rid of TQ management or finish the development of the UV8.
