    has anyone ever swapped out a 4.6 for a 5.7? If so how much of a project is it? Will it bolt right up to the transmission I have?

    Haha that’s awesome. Well I have a tundra that is in mint condition and I’d love to swap out the engine when it wears out and if the truck is still in great condition I’d love to put the power house under the hood

    Easiest way to remove the engine is to lift the cab/body. Unless you have access to a lift it would not be cost effective to swap a 4.6 to a 5.7
    If you do, swapping is pretty straight forward but you will need the ecu from the 5.7 which means you need the key as the ecu is coded to the immobilizer chip on the key.
    The tranny will bolt up but the ab60 5.7 gear ratios are different from the a760 4.6 tranny, not to mention the a760 and 9.5 rear end was not designed to handle the torque of a 5.7
    Considering all the labor and parts required to swap correctly involved, WHY?... just buy a 5.7

    Buy a new truck with 5.7L would be easier. :D

    Not to hijack the thread but looking to drop a good low mileage earlier ‘01 4.7 motor from a rusty-ass truck into a solid 2006 with a crapped out motor.
    I’ll have the entire ‘01 donor truck with ecu and harness trans etc. Suggestions that I need to worry about? Long time Toyo owner with engine swap experience (50-60s cars) thanks in advance

    You can only use the short block from the 2001 and have to transfer the heads and intake from your 2006.
    Non vvti vs vvti. Having swapped 50-60 cars, this should not be a problem but why? Find a vvti motor to do the swap

    Thanks for the input Nick. As stated I have a perfectly good ‘01 motor with 115k with the truck rotting away around it and the chance to pick up a very solid and clean ‘06 with a blown motor. Wondering if it would work. I have 50’s and 60’s GM toys but use Toyo daily drivers. Thanks again

    I know this is an old thread and for what it’s worth, I started investigating this possibility on my 2015 when I got a new trailer, only to find out the 4.6 got a little upset trying to tow it.
    I may be wrong, but the idea of swapping the engine seemed good at the surface but I really got concerned about gear ratios, transmission interactions with the ECU and the rear end being able to hold up to the stress.
    Even if I got that all sorted out, I was really concerned that if I managed to get in a wreck, my insurance might deny the claim if my truck was above capacity.
    All that aside, I ultimately traded my truck in and got a brand new 21 just like it, but with the bigger engine and 6 miles on the odometer. The net difference was about $10k.
    Before everyone says that’s too much, consider what a good used engine would cost, then all the conversion hardware to go along with it; the new ECU, etc.
    Then there’s all the time you’d spend and the fact that your resale would be difficult with all the mods. A dealer would just give you low book (less if they knew you did the swap) and a private party may avoid it altogether. For me the path of least resistance was simply to get a new truck.
    The used truck market is hot right now. Dealers are going to great lengths to acquire used vehicles. All that said, I’d take the high road and trade it in. I do fully understand that everyone’s situation is different though.
    Cheers!

    $10K would be well worth it for that, especially with super low interest rates. You could blow through $5000+ on an engine swap pretty easily and be left with a truck that doesn't work properly in the end.
