LX450 LM4/4L60E Swap

I finally bought the oil pan used on LH8 V8 equipped 4wd Hummer H3 Alphas and Colorados. The pan looks like it will clear the driveline at stock height.

Before removing the 302-1 style pan, I removed the front springs to test driveline clearance. The front diff hits the oil pan before the driver's side bump stop contacts.

Do you know the part number for the oil pickup that goes with that pan?

I don’t unfortunately. I ordered an eBay copy kit.

Finished installing the H3 pan today. It wasn't the final solution I was hoping it would be but I'm going to have to run with it for now.

There is now plenty of diff clearance at full compression; even enough for lateral movement that may happen with bushing flex. However, the H3 pan is taller and will barely touch the tie rod under full compression. Contact will definitely be more severe under more dynamic compression of the front end. Also, the pan only allows for one of the two bell housing bolts to be used. I'm not sure how bad this is but I'm all out of weekend and money.

As for the Labwork pan kit itself, I had to slightly bend the pickup support arm for it to match up with the crankshaft scraper tray bolts. Also, I had to trim the pan baffle slightly to clear the pickup.

For now, I'm going to get bump stop drops until I can afford the Holley 302-4 pan or until they make a knockoff one of those.
