    L94 to L96 engine swap

    I finally got this done a couple weeks ago. Thanks to everyone here for your input, especially Swathdiver. Your assessment was spot on. This was plug and play with the tune, runs great on regular gas. I think we're going to go back into the tune a little, we just used the stock L96 parameters...

    Need new 6.2 L86 Engine...but indefinite backorder???

    You could probably save a lot of money by buying a good used engine from a reputable used auto parts place like LKQ. They typically offer good warranties on lower mileage units.Car-part.com is another good place to look. I just put a 95,000 mile engine in my 2012 Yukon XL Denali, cost me $3500...

    2021 Yukon XL Denali - third engine and still under 42k miles

    I agree, my 2012 Denali has been mostly good except for the L94. AFM/DOD issues mostly. I'm going to pull the 6.2 and put in a L96 truck engine. My 2003 Suburban 2500 4x4 has been practically bulletproof. 300,000 plus miles and still solid and reliable. Makes me wonder how things could have...

    L94 to L96 engine swap

    Thanks for the link. That site is very helpful. I've been getting a good bit of information there and that's where I kind of figured out which 6.0 engines will work for me.

    L94 to L96 engine swap

    Thanks for your reply. Earlier 6.0s like the LQ4 and LQ9 didn't have VVT, but later engines L96 and LY6 do have it. As far as I can tell, those are the only engines that will swap in easily.

    L94 to L96 engine swap

    I've pretty much exhausted the search for a reasonably priced L92 or L9H. At this point, I'm pretty sure I'm going to end up with an iron block 6.0. I'd like to eliminate AFM/DOD and keep the VVT. Aside from the L96, does anyone know which other engines will be compatible? I don't have a problem...

    L94 to L96 engine swap

    Thanks for the input. A big part of my problem is that I'll be doing this in the shop and I'll have limited time. It's going to have to be a weekend engine replacement. I won't be able to tie up a bay in that shop for an extended period of time. The other aspect is that my wife uses this for...

    L94 to L96 engine swap

    That's what i was originally going to do and I've looked all over for them and can't find one at a decent price. The L9H would still be my first choice. It seems like everyone wants 4K or more. I can get a newer L96 for half of that. Then there's the question of durability. I spend a good bit of...

    L94 to L96 engine swap

    Thanks for confirming what I was thinking. At the risk of making this a bit more complicated, I was considering using a L9H cam, almost exactly the same as the L94, and my L94 injectors. I'm guessing that might get me to 380 HP or so and still allow regular gas. Just a thought. Do you know of a...

    L94 to L96 engine swap

    Thanks for the input. The L92 or L9H swap was my first idea, but those engines are $4000 and up at the salvage yards. A good L96 is $2500. I'll have to look into the intake port issue. Someone else suggested that I use my L94 heads and intake on the 6.0 block, seems feasible, but that will...

    L94 to L96 engine swap

    Thanks! I think you’re right about the tune, starting with the AFM delete. The engine I’m looking at was mated to a 6L90 and my truck has a 6L80. I’m pretty sure the flex plates and bell housings are the same but I’ll verify.

    L94 to L96 engine swap

    The engine you’re thinking of in the earlier Denali is the L92.

    L94 to L96 engine swap

    My 2012 1500XL Denali has a L94 aluminum block 6.2 with AFM/DOD and VVT. Uses premium fuel. The L96 is an iron block 6.0 with VVT but no AFM, regular gas. They’re found in 2010-17 2500 and 3500 trucks and vans. I’m wondering if anyone has tried this swap and had problems.

    L94 to L96 engine swap

    Looking for advice, the engine in my 2012 Denali has had a few problems over the years and has recently developed a tap in the bottom. We suspect a cracked piston or wrist pin issue. I’ve also had AFM related issues a few times. I’m thinking about replacing it wit an L96 truck engine. I realize...
