Finally an Engine(LM4) What the hell is... this thing sticking out of the crank case?
Thanks to those of you who pushed me not to buy one of those LM7s for $800. A highschool teacher responded to my ad and sold me a 06 LM4 out of a Buick Rainier with less than 12k on it for $350! The guy said the truck was in a front end collision and he's had the engine in his shop since 06. It didn't have an alternator and I found out afterwards that the starter is missing too. But he gave me the entire wiring harness for the car it seems like along with the PCM. Here are some pics.
Summary:
Got for $350 the following:
LH6* correction I thought it was an LM4, but its not.
A/C
Wiring Harness
PCM
Powersteering pump
Missing:
Intake
Throttlebody
Starter
Alternator
This is the thing I can't identify
This is what came outta there before

According to Wikipedia its an LH6.
2005-2007 Buick Rainier
LH6
The LH6 with Active Fuel Management replaced the LM4 for 2005, and was the first of the Generation IV small block V8 truck engines to go into production. It is the aluminum block counterpart to the LY5.

Ok that's what I figured it was. I didn't realize I was buying a gen IV. I already bought a ls1 intake and corvette fuel rails. Will those still bolt up to this or am I going to have to buy LS2 stuff? I take it the holes in the oil pan are just to allow for oiling to the front diff and that replacing this with a regular oil pan will fix my problem?

True about the find, that's really awesome. Up here an aluminum/iron/anything-Gen 3/4 usually costs an arm and a leg... and also a kidney.. it's annoying.

You have to search 5.3l or 6.0l or vortec. I've been doing that for the last 3 months and these are the only 4 engines i've turned up. The one I just got was some1 responding to my wanted ad.

The thing on the passenger side of the engine is the front diff actuator and the thing on the other side is the front diff. You can just unbolt those from the oil pan and there is a hole right through the center of the pan. Gm did this to be able to set the engine lower in the vehicle on the trailblazers, envoys, and raniers.
