Sorry if this sounds like a dumb question but I am racking my brain a little on what direction to go with this.

I have a 2008 LY6 block...I am using none of the VVT stuff, only the block and rotating assembly. I plan on switching over the front to all LS2 stuff - timing cover, cam sensor, etc...and with the L92 heads I might use the L76 intake but more than likely a carb style intake with a 90-deg because the throttle body ends up in a much better place for plumming. This is going to be a turbo build, btw, and I am matching it up with a 4L60e transmission and speed density tuning.

That all being said, can I use the harness from a '05/'06 GTO and reprogram for the 4L60E instead of the 65E?

What about if I wanted to use a cable driven throttle body? Could I use an Fbody PCM and would I need to change up the timing cover/cam sensor or could that be made to work with the earlier set up?

Thanks in advance guys...as you can tell I am WAY over thinking it...
