2006 LH6 out of an Envoy Denali. I bought the motor before I knew much about these, turns out they're a b*st*rd child lol. I just knew it was aluminum and that's what I wanted for my handling goals later on
- Gen4 aluminum block with knock sensors on the sides
- Gen4 rods
- 24X Gen3 timing system
- Uses an E40 computer (only these, 04/05 GTOs and SSRs used that comp)
- 799 heads (same as 243s)
- TBSS style intake
- 30lb injectors
Originally (3yrs ago) it was thrown in with the 4L65E that came with it and a BTR Stage 4 V2 truck cam (.553/.553 224/230 109lsa) and LS6 springs.
Then last fall I pulled it out for a reseal (rear main) and to swap to a T56. So since I didn't have to worry about converter walk anymore, I stepped up to the TSP Bald Eagle N/A cam (.600/.600 227/234 111lsa), double valve springs, a CHE trunnion kit and 50lb/hr injectors.
