Made more progress on the truck over the weekend. Not as much as I had hoped, but all in all, I am good with what got done.
Got the engine frame stands smoothed up and painted, bolted in and got the mock up engine out of the way. Pulled the front boot to make things easier and go get a few refinements made when putting them back on in hopes of making it to C10's in the Park in a couple weeks. Set up these fabricated mounts to allow me to use the stock truck oil pan and not hang below the front cross member. Looks like it is maybe about 1/8"-1/4" below the cross member. I can fix that with a spacer later, but for now, I am good with it. Also, the bottom of the trans pan for the 4L80e is level with the bottom of the frame rail. Pretty happy with that. I used a Ingenuity Fab and Speed transmission cross member, but still had to use a 1.5" spacer between the cross member pad and the Energy Suspension Trans mount. I cut out the floor thinking I would NEED the high hump, but the way I positioned everything, I might have gotten away with the factory low hump floor.
I got the 6.0 LQ4 and the 4L80e installed for the final time and put the Headman Headers that I had left over from the red truck. They fit great. Will work on the final version of the exhaust after C10's in the Park. Plan is to get it running and drivable in and out of the park for the weekend. I got lots to get accomplished by the 16th!
