Merv, the LS2 was supplied to HSV for their range, whereas the L76 is the engine supplied to Holden for the SS Commodore. Both are Euro 3 emissions compliant. They're different in that the displacement on demand (DoD) is working for the LS2, but with the L76 some of the DoD hardware is there but it's not enabled. I believe they have different heads (better flowing on the L76?) but the L76 has a small cam and makes less power out of the box. Both engines respond terrifically to a chip/cam/exhaust package and the L76 is a thousand or so $$$ cheaper. They also have different computers and I'm sure there's some other details that I've overlooked...
