A gen 3 6.0 into a newer gen 4 computer? I believe all that im going to need is the 3 bolt 4x cam gear timing set and swap the crank trigger back up to a 58 tooth and reuse the factory front timing cover with the sensor in it. Anything else im missing? want to have my ducts in a row before decommissioning my 07 chevy truck with 221,000 miles.
