Help selecting a crate engine

[Black03SS_NJ]

I've got an L76 2007 Avalanche (6.0 AFM/VVT) and I plan to replace the engine. I am planning to install a factory replacement, and the correct crate engine is 19168201. However, while I'm at it, I'd like to add a cam. So rather than delete the AFM/VVT, which would require partial disassembly of the new engine (and probably void the warranty), I'd like to find a replacement engine that suits my needs. I've looked through dozens of options but can't seem to find what I need.

 

Can someone point me towards a Gen III/IV replacement engine that's aluminum 6.0 block, LS3/L92 style heads, without AFM or VVT? Even pinning down a vehicle that had such an engine stock would put me heading in the right direction. Thanks for the help.

Easy way is trying to locate a Crate LS2 long block. Or just going LS3. I think there is a vode L75 or L77 wich is what the caprice ppv has. Dont know if it has AFM in it. VVT isnt necessarily a bad thing

This what I got from Wiki regarding which vehicles used an aluminum block 6.0L. Hope it helps in your search.

L76

The L76 is derived from the LS2. And like the LS2 it features an aluminum engine block. However, the L76 does feature Active fuel management (AFM). While the displacement on demand technology was disabled on Holdens, this feature is enabled on the 2008 Pontiac G8 GT and subsequently refitted in the 2009 model Holdens with AFM enabled, but only on models fitted with the 6L80 Automatic Transmission. The engine also meets Euro III emissions requirements. Output is 348 bhp (260 kW) at 5600 rpm and 376 lb·ft (510 N·m) at 4400 rpm for the Holden variant, and 361 bhp (269 kW) and 385 lb·ft (522 N·m) for the G8 GT.^[11] The Vortec 6000 or new VortecMax version is based on the Holden L76 engine, and features variable cam phasing, along with Active Fuel Management. It can be considered the replacement for the Generation III LQ9 engine. It produces 367 hp (274 kW) at 5400 rpm and 375 lb·ft (508 N·m) at 4400 rpm. Production of the Vortec 6000 started in late 2006, and is only available with the new body style Silverado and Sierra. The final year for the option of the VortecMax engine was 2009 in the Silverado and Sierra. vin code (Y)

Also from continued reading this may help as well...

 

L98

For the tuned-port Generation I engine of the same RPO, see Chevrolet L98

The L98 is a slightly modified version of the L76. Since Holden did not use the displacement on demand technology of the L76, some redundant hardware was removed to form the L98. Power increased to 362 bhp (270 kW) at 5700 rpm and 391 lb·ft (530 N·m) at 4400 rpm.

Applications:

• 2006 (MY06) Holden VZ SS Thunder Ute
• 2006–2010 Holden VE Commodore (manual only from 2008–2010)
• 2006–2010 Holden VE Ute (manual only from 2008–2010)
• 2006–2008 Holden WM Statesman/Caprice

The L98 version did not use the AFM or DoD (or whatever else it's been called over the years.)

Thanks for the help everyone. It looks like my options are basically either and L92/LS3 or buying another L76 and deleting AFM and VVT so I can add a cam.
