LQ4 intake/harness help/advise

[TazmanB]

Well I had a complete 01 LQ4 out of an 01 Denali fall into my lap. It is a complete motor minus the wiring harness, ecm and of course no pedal or TAC. I was told the motor was no good so I tore it down and found it had a spun main bearing. I found a fresh rebuilt 06 LQ4 short block for CHEAP and swapped the heads and everything else over and now it is sitting as a long block. I have been trying to educate myself on the Vortec motors and have come across several differing opinions (surprise surprise!!!)

Anyway to get to the questions and to see if I can clear the mud out of my head a little bit here goes. I have everything I need to take it back to a complete 01 style motor but have been looking for a wiring harness, ecm, pedal and TAC that will work and get it running. From what I have seen the 01-02 LQ4's seem to be a pain in the a$$ since they are what seems to unique to those years. And to add to it the required parts to get it running (ecm and TAC) appear to be much higher priced. I was thinking if I could find a complete 06 intake with fuel rails, injectors and TB then I could get the less expensive ecm, pedal and TAC. Does this sound like a good route to go or should I be looked at doing something else. I am trying to put this motor back together as inexpensively as possible because cost is an issue.

Oh and I will be looking to put a 4l80e with it.
