Parting out 4.6is engine and transmission to replace with LY6 Engine

Well the day has finally come and I'm looking forward to making this dream a reality. Last winter my crank case vent hose froze which pressured up my engine and blew all of the oil out of my engine. As soon as my oil light went on, I shut the engine off and pulled over FAST!! I had my X5 flat decked back to my house and the diagnosis started. At first one it looked like my one bank wasn't firing so I bought the expensive engine timing kit and made made sure my engine was still in time while re-tightening my cam position sensor. With both banks firing again, I thought I had my problems fixed but while it was still running in my garage something sounded off so I unbolted the oil pan and upper oil pan to have a look at the main bearings and found the bearing closest to the fire wall was cooked so I'm parting out the engine and transmission and installing an LY6 6.0L Chevy engine and transmission. It'll be a project and a half but I have some good friends that will help with the build. I'll post pics and updates along the way.


1. I replaced the transmission about 20,000kms ago with one straight from ZF in New York. No issues with the new tranny at all.


2. I had gotten the timing chain and guides done also right around that time so that's all quite new also.



3. I had the alternator rebuilt by my good friend at Treasure Electric in Calgary with all new mil-spec parts. He did an awesome job and ran perfect around the same time also.
