A new DELPHI Part # AF10043 (2006 GTO) part is available from rockauto for $98. For o2 sensors, DELPHI Part # ES20007 is available for $41 each. I think Speartech quoted $450 for their o2/MAF package which is probably for AC/Delco branded parts. Chances are the Delphi parts are the same since Delphi makes the parts for GM. BTW it took Speartech about 6 weeks to ship my order. My project is a 68 Lemans being converted to a GTO with LS3/4L70E. I should probably start a thread for my project so as not to hi-jack your thread. It would appear that both of us are facing the same problems at about the same time.
Thank you for your very valuable input here, in no way would I consider calling any of this very helpful info that's related to both of our projects a thread hijack.

Please do start a thread on your '68 GTO project. I'm sure there would be a lot PY members who would be interested in your later generation A-body project with the LS3/4L70E drivetrain going in.

I was told my harness package should be ready in about 3-1/2 weeks due to the holidays, we'll see.

So the LS2 GTO MAF is compatible with the LS3 engine? Interesting, I suppose the fact that the LS3 is a drive-by-wire engine doesn't have any impact on the MAF from the LS2 being useable.

Thanks again for your most helpful input. I'll look into the DELPHI # AF10043 MAF sensor and #ES20007 O2 sensor pieces from Rock Auto, this will really help save me a nice chunk of change.

EDIT: After doing some checking on the Rock Auto site I saw the # ES20007 O2 sensor is a 2004 Corvette part, whereas the # ES20009 O2 sensor ($53.79 each) is for the 2005-2008 Corvette.

Wouldn't the # ES20009 be the correct one since it matches the year of the engine I'm using? Or could it be the # ES20007 is functionally the same but fits into a different size (smaller?) O2 sensor bung that's a better fit where I will need to install it, directly after the header collectors welded into the exhaust pipes?

I can also see from looking through the Rock Auto catalog that the # AF10043 MAF sensor is used on quite a large number of different GM cars:

BUICK (2004 - 2007)
CADILLAC (2000 - 2006)
CHEVROLET (1999 - 2008)
GMC (1999 - 2008)
HUMMER (2003 - 2008)
ISUZU (2003 - 2006)
OLDSMOBILE (2001 - 2003)
PONTIAC (2005 - 2006)
SAAB (2005 - 2008)
