So no timing chains on other 4.7's. I'll likely stick to the most compatible models for a donor.
My new plan is to:
-buy used engine with ~150k miles
-reseal vc's, main's front and rear, cams
-tb kit w/water pump
-engine accessories (alt, starter, etc)
-drive it for another 300k ( give or take a 100k or so )
Meanwhile, I'll have a good core to rebuild slowly, possibly with plans for a power adder in the future.

Don't forget to bypass the AIP system if the engine has it

Mine is an '03, not sure what year they started that, but it was after '03.

2005 is when they started having the AIP for the V8s.

I think I can get a pull out with about 150k miles, reseal it and do the water pump and tb for about $1000. I figured I'd be that far into my current engine with only doing the top end.
This brings me to the next question. Will a tundra engine swap in? I think I rember there being differences like the fact that the tundra and sequoia engines use a timing chain and maybe a different intake, but will they interchange? I've found several very low mileage (sub 50k) tundra engines for the same prices as the 4runner/GX engines.

Tundra and Sequoia from same year will interchange blocks. The intakes and exhaust parts do not interchange or fit. I rebuilt mine and am very happy with how it turned out, I am still driving it today. I pulled it and put in new pistons, rings, main and piston pin bearings and lightly honed the cylinders before reassembling. I will tell you that the heads are extremely difficult to set up and I would definitely have them decked and rebuilt before installing them into the engine again. And there are a ton of seals you have to change so don't flinch if the cost of the seal kit is astronomical. Mine was about 500 from the dealer.

I dug up this old thread I started a couple years ago. I still haven’t got around to this project (insert an excuse of your choice). I’m currently looking for another pull out and will go through it before swapping it in. My question is whether or not there is anything else I should address while the engine is out? More specifically, should I do anything with the Trans or TC? I’ve been changing the trans fluid (drain and fill, no filter) every 20k since i’ve had it and it’s never so much as missed a shift. I thought about putting a new TC in just because, since I am sitting at 310,000 miles now. I’m open to anyone’s thoughts or concerns.
