Replacing 5.7 Vortec Engine To Denali 6.2 Engine

[Silver Yukon]

Good day every one

I've got a 1997 GMC Yukon SLT 4WD with the original Engine. And also I have a 2008 yukon Denali which I made an accident with it few years ago. So now I'm thinking to take the Denali engine and put it to the old guy. I want to know what do I need to that. I think the hardest thing is how to fix the ECU. And because the Denali got an electrical throttle which throttle should I put.

Im tuned into this one , Just got word of a friend that has a 6.2 in his garage he has no plans for , now if only i can scape up a couple hundred dollars without the wife noticing haha,

IMO I would keep the cabled throttle vs electrical. but I guess I'm just old school, However I have no idea how easy or hard the swap would be if even possible. I hope some of the engine swap gurus get in here and start a good discussion . Im subs

Thats why I want to do it now before I get married next year

I'd choose the cabled one too I think its much easier to fix.

Yea cable is way easier. Electronic is not a good design imo. Kiss keep it stupid simple

Using the electronic one should not be an issue for you. and what do you need to fix on the PCM anyways?

that is my big issue

 

[SunlitComet]

You would be using the powertrain and it computers of the newer engine for the most part so why is it an issue?

Use everything from the '08 engine/trans and PCM including drive by wire throttle since you have complete donor vehicle.
I've read some times mixing and matching gas pedal assembly/module between years/models could be a nightmare but you won't have that problem.

There are LSx swap parts and info on the net.

Good luck with your project.

Gzes… The correct use of that acronym is Keep It Simple Stupid
