I cam across a good deal on a 2009 6.0 iron block with l92 heads on it, its a long block, And i was wondering if i could use a 2003 year model computer and wireing harness on it? I would like to buy it, because i have a few 2003ish harnesses, and computers? Is this possible?
I know the 2007+ motors have the variable valve timing, and didnt know if that would keep me from this conversoin?
Any help would be great!

 

You will likely need to have a custom os loaded on the ECU because I believe they switched the tooth number on the reluctor wheel.
