I still have to clean up the area on the frame where the new weld-in engine mounts will go with the grinder. When I do that, I will do a little cleaning. I would love to make it look new in there, but I lack a pressure washer 
Excellent pictorial writeup. Up until now, the AA adapter was a bit of an enigma to me.
So, the tcase will be in the stock location is my guess. That means that your entire drivetrain is fixed and your engine will end up wherever it ends up? I'm guessing that the two oem driveshafts will be re-used w/o modification?

It is pretty
isn't it?I have the PS hose and fitting set to the side for you. The TCU is still in the truck - I will pull it out once I get to the wiring stage. BTW, I forgot to give you the MAF meter - it's still attached to the air intake hose. I will set that aside for you as well.

Yes - this is the plan. The t-case stays in it's stock location so in theory, no DS changes should be needed (except the trans pan clearance issue will have to be addressed at some point). The engine will go where it goes.

I have done a few others so it was old hat to me. Just measure twice and use the tape as a guide to help with keeping a straight cut. It's not really an exact cut since the spud shaft can slide a little on the splines. If anything, it's better to cut a little more off to allow for heat expansion, rather than not cut off enough and have some bearings get toasted because of the output shaft jamming into the input shaft of the t-case.
Unlike other conversions of this type, I see that you're using the 80 series Tcase and not the 60 or 62 Tcase. So, Marks adapters make both adapters and you opted for the 80 tcase adapters?
I assume that it took two months for the parts to arrive is because of that's how often they ship a container full across the pond?

Marks does make a few different adapters that will work with either the 60 series or 80 series cases. They also make them to fit the various GM automatics.I am keeping the 80 series case because I want to retain the full time option. It's nice to have because of the weather we get in CO. Plus, it's a monster t-case. I don't think it will have any issues with the v8. Like everything else, toyota definitely over-spec'd it.I ordered the kit from Advanced Adapters back in early Nov. The purchasing manager told me I had missed the stocking order from Marks by just a few days, so I could either wait for the next one, or have Marks ship me the adapter directly for an additional charge. The charge would have been about $250, so I opted to wait it out. I think the holidays played a role in delaying things because the adapter sat at the port of LA over Christmas and New Years. Can't really blame AA for the delays - it's just the way things are when ordering something that is custom made, and it's coming from half way around the world. Besides, try to order an Atlas t-case right now. It's typically a 2 months wait to have one built so it's simply par for the course.

I have stripped out most of the 1FZ ecu wires from the toyota harness and will integrate it with the GM harness. Once everything is wired and working as it should, I will post up my spread sheets to help others wanting to do this swap.

Very cool and much appreciated
I am sure a lot of people are waiting. I just want to be sure it works and not pass out bad info
Kurt did something similar and he made life size print outs of the schematic and pasted them all over the wall of his huge shop. It was impressive and imposing!
I can't wait to see what you have come up with. It should help the folks who are considering the Atlas I-6 conversion.

Car Craft has a special edition out on LS swaps. It seems like there are a lot of options, and price points, for stand alone ecu swaps.
The 454 LSX would be pretty awesome too, same block dimensions as the 5.3l. imagine four wheel burnouts

getting there - I have been whittling away at removing what's left of the stock engine stands. Toyota did a very good job at making sure they would never be removed.
Passenger side stripped and cleaned up and ready for the AA mount.
Still working on the driver's side.
I am having to work around the brake lines and don't want to any damage so it's slow going.
Tools of the trade.
I lack a cutting torch or plasma

no - the maximum width of the engine with the ls3 exhaust manifolds is about 25 inches, and the distance between the frame rails matches this. The towers are outboard the frame rail. There's plenty of room.
