LS2 is 6 litre, was it a HSV rory?Get a late VY /VZ if you can..mine was one of the last VYs and it had an LS2 in it..ther are all VF...very early ones needed rebuilds as they chewed oil by the gallons on some...Later one the better. Google LS1/2 or look on the LS1 forum...there was an article on how to tell the difference from LS1 to LS2.

There all good from 2000 onwards, the early VT ones had the standard LS1 manifold and love to make some noise.
Whether its now or in 5 years time your going to be rebuilding it, so just buy a core and build it up now and it will go forever.
There too easy to make power in standard form, then you start pushing them and after a little while your luck runs out. Boom it goes and out comes the cheque book.

I think you mean LS6, they ran out of LS1's and some got the complete LS6, same as the other LS1's but different head/camshaft.They ran out of LS1s at the end of VY production...so the last batch were 5.7 LS2s..I didnt believe it either but then and checked mine and bugger me..there it was..an LS2...info on LS1 forums..
R
The LS2 is/was a 6L.

rory, are you saying your late VY had an LS6 engine, not an LS1 ?Stand corrected...LS1LX is correct...It was an LS6 not LS2.

How did you ID it ?

LS6
GM LS6 engine in a Chevrolet Corvette Z06LS6 can also refer to a 454 in� Chevrolet Big-Block engine of the 1970s
The LS6 is a higher-output version of GM's LS1 engine. It is an all-aluminum 5.7 L (346 in�) pushrod engine. The initial 2001 LS6 produced 385 hp (287 kW) and 385 ft�lbf (522 N�m), but the engine was modified for 2002 through 2004 to produce 405 hp (302 kW) and 400 ft�lbf (542 N�m) of torque. The LS6 was originally only used in the high-performance C5 Corvette Z06 model, with the Cadillac CTS V-Series getting the 400 hp engine later. The V-Series used the LS6 for two years before being replaced by the LS2 in 2006. For 2006, the Z06 replaced the LS6 with the new 7.0L LS7.
The LS6 shares its basic block architecture with the GM LS1 engine, but other changes were made to the design such as windows cast into the block between cylinders, improved main web strength and bay to bay breathing, an intake manifold and MAF-sensor with higher flow, a camshaft with higher lift and more duration, a higher compression ratio and a revised oiling system better suited to high lateral acceleration. [1]
The casting number, located on the top rear edge of the block, is 12561168.
Applications:
2001-2004 Chevrolet Corvette C5 Z06
2004-2005 Cadillac CTS V-Series

rory, if the last of the VYs had LS6s, then 2004 & 2005 (non-HSV) VZs must have had them as well, prior to the L76 in 2006.
Does anyone have any documentary evidence of this.

Just read on the LS1 forum that Holden "LS6" engines are not proper LS6. They got the block and intake but LS1 heads and cam and tune. This is a cut and paste off the site:
Bolt a set of LS6 head assemblies and cam on your VYII or SIII Monaro and you have an LS6 less the PCM tune which only requires tweaking on the rev limit anyhow. They already have the block and intake. The only real difference is complete LS6s came from the US - I think the 'Vette plant and not Canada - and the LS6 block casting has better windage between cylinders to reduce pumping losses. It is also seems more stable in the bore alignment which is why GM adopted it, partly to reduce the oiling problems.

Check your heads..mine had the LS6 ones on them....I understood they just sent them in as complete crate engines to finish VY production. Everyone that drove mine who owned an LS1 commented on how quick it was...I thought it was just me..It was a great car..Pallbag should have bought it!

The the later ones they started sharing the same LS6 block instead of 2 different blocks.
In the VY they couldnt keep up with demand, thats how some ended up with a complete LS6 engine with the '243 LS6 heads.
The stock LS2 is pretty much an LS6 engine minus sodium filled valves and its 0.3L larger capacity.
