I bought my wife an 04 Dakota 4 door truck a while back, with a locked up 4.7 motor. It's a nice little truck, and I got it dirt cheap. I bought a remanned 4.7 from Powertrain to put back in it. They do a lot of upgrades to their motors that other remanufacturers don't. They use better pistons with coated skirts, and they have drilled out and polished the oil return holes for better flow. They install new valve seats in the heads, and pin them in so they won't drop out. They also use a multi layer steel head gasket to help prevent the head gasket issue. I'm a few days away from starting it up, as I just got it dropped in the truck with a low mile 545 RFE transmission, right before we left for the beach. I'll be honest, and say I was gonna drop a low mile 5.3 LS motor in it with a 4L80E transmission, but we live in a smog inspection county and the GM ECM to run the engine/trans would not pass. You can about stand back and throw an LS in a Dakota if you were strong enough! I think the new 4.7 and 545 will last as long as she wants/needs the truck. I change oil every 3K miles, and stay after maintenance...so I ain't skeered of no 4.7!

Those things you mention are sales gimmicks, the factory pistons are coated skirts and don't fail, valve seats only fall out if very severly overheated, oil return is not a problem on these like it is on a 2.7. Good upgrades would involve the timing chains and chain guides and something to keep the rockers from falling off after sitting a long time.

I took the heads off my old motor before I sent it in as a core, and the skirts were definitely not coated. I took 2 pistons out to free the motor up and make it turn before sending it in. There is an upgrade to a new type of chain tensioners, with some type of new design plastic or Teflon. It hopefully won't sit long enough to spit out a rocker arm, as is common in wore out motors. There's some kind of rocker arm fix on the market for 4.7 and 3.7, but I've wondered if it's a snake oil salesman!
