Escalade motor
 

Bought the wife a new suv and have taken her 2007 Escalade to use motor and trans for my 67 c10 project. Looking for advice on what to do with that motor to up the hp to 600 plus. Should I use the stick trans and get it re flashed to be more aggressive or can I even do that. Stock is terrible. Also what electronics will I need to have the thing run properly. Need some advice before I rip the motor out and don’t forget anything that I would need and junk the rest of the vehicle.

Thanks

Welcome aboard! Sounds like a nice plan. I am recommending you do some searches in the LSx section of the forum and as you move forward ask specific questions there. The amont of LSx swap information there is quite large and goes across model years. So your odds of finding Cadillac specific information is better.
Good luck.

Re: Escalade motor
 

Do you like the dated chassis on the truck? I bought a cab and stepside bed and plan on putting them on a Tahoe/Escalade/Yukon type chassis. Old look with newer handling. The wheelbase is within an inch of the shortbed C10.

Re: Escalade motor
 

I have done a frame off rebuild, also its a long bed as I like the look of the longer bed once its air bagged. So sticking with the stock chassis for now. Just want to know really is there anything I should be looking out for with this swap. Best motor mounts to use That type of thing once I start I will have many more questions Im sure. Also should I use the wiring harness out of the escalade if Im planning on using seats and air conditioning from same vehicle maybe a few of the other luxury interior items it has as well

Thanks

The engine in my C30 came from a Escalade..its no slouch..turned 344hp/399tq on the dyno..stock except for headers...got a nv4500 behind it..and 4.10s

Re: Escalade motor
 

Look up in the ls sticky lots of info there look at other threads in this category and look at build threads by ls1nova71

Re: Escalade motor
 

your 07 should be a 6.2L with VVT, non-DOD (cylinder deactivation) ?

to get from ~400stock hp to 600, I think you'd need to rid of the VVT, cause you can't go big enough with the cam to get there and keep VVT.
Pull heads, plan on having port work/milling
get a 3 bolt style cam and good 4x roller timing set for it (assuming yours has a single bolt and 4x wheel)
Large cam / good lifters / pushrods / valve springs
good intake system (holley high ram or fit the COPO setup if you can fit it)

well thought out top end and valvetrain can do this with the stock short block
you might need to notch pistons for valve reliefs

Another good option I've done is use the latest Mahle forged pistons, they will have reliefs, and thinner ring set (1/1/2mm) that help power. Do a fresh hone on the block or go +.005 over

T56 will bolt right up, all you need is pilot bearing in the crank
I'd think you can use the computer and harness, I don't believe there's a reason you can't with a re-tune. If you go manual you'd remove the trans harness or send it out for custom work. You'd need to pin in reverse lockout, back up lights, VSS etc. I'm not well versed in using the Auto harness with a T56 swap, for mine I chose to use a 2006 GTO car harness since the T56 portion and computer were already setup for it

Re: Escalade motor
 

That's a good engine to start with. Getting to the 600HP mark takes a bit more than the 500 mark.

I would consider a 4L80E for that power level and a turbo will get you there easy. I agree with 71cadc10 that you can get there naturally aspirated, but it does take a lot of work and you might be money ahead with a turbo. I won't get into the details, but adding a turbo requires minimal work to the engine itself, but does require a lot of extra parts in the engine bay.

I would recommend watching Richard Holdener's videos on YouTube, he has done everyone a favor in dyno testing so many engines and power adders to show you what gives you the best bang for the buck.

As far as the brains of the system, you can either keep the stock engine PCM and find someone to tune it professionally, or you can get the Holley Terminator X Max system that will control the engine, transmission, and drive by wire throttle. It is self-learning so no need for fine tuning unless you want to. The engine PCM is separate from the computer that controls the rest of the vehicle which is nice.

You can also get on LS1Tech website and do some research.

I don't know about using the A/C from the Escalade though. It's hard to make that system fit in a C10 and also function as a standalone unit as the engine computer does not control it. You're better off with Vintage Air. The seats shouldn't be a big deal - I have seats from an 04 Escalade in my truck and all they need is power and ground. The rest of the wires that I didn't use were for memory. It has all adjustments working with just those two wires hooked up to them.

Re: Escalade motor
 

To get 600 rwhp and keep it NA you will need the best heads like AFR along with a monster cam which may not be real streetable or easy to tune.
As said above a turbo or super charger would be easier.

Re: Escalade motor
 

Watch Richard Holdener's vids on Youtube. He has a vid of 10 combos just for a 6.0, would apply to a 6.2 as well. I have an LQ4 I got pretty cheap, and want to keep it simple, already have the TBSS intake, either 706/862 or 799 heads, maybe the stock 317s, Sloppy stage 2 cam and a turbo. He has many vids on boost'n LS's, how to make 400, 500, up to 1000 horses. Says what motor, intake, turbo, etc. I like his vids, but its the typical "perfect world" dyno numbers.

Here is a richards 6 liter torque build
I am looking at it for a 4x4 build

Re: Escalade motor
 

600 rwhp NA is out of the question...he is talking 600hp crank.

AFR heads for sure aint gonna do it on a 6.2L

Re: Escalade motor
 

600NA is not out of the question whether OP is talking to the wheel or crank, which I don't believe he ever stated. It's just going to be a max effort thing and will cost a lot to get there at the sacrifice of a budget or longevity.

Just depends how much he wants to spend and how hi he wants to rev it.

But like you said earlier, aftermarket 3 bolt cam, good chain, good lifters, and some serious head work are in order. Might be worth it to look into Texas speed or even go all out like FED for either of their CNC programs on those stock heads vs buying new.



OP, what are you're goals with the truck, drag race, auto x, spirited driving, cruising to the local cars and coffee? Don't get hung up on a #goal, figure out your goal and use for the truck. There are TONS of proven combos out there for a 6.2. They take very well to boost in stock form as well. Stock heads with upgraded rocker trunnions and springs, an LS3 car intake, swap the cam out and throw a china turbo on it and you're at 600 all day, with relatively low levels of boost and room to grow.

Also with how you will use it and who will tune it will dictate what ECM you might want to go with. If you are going to be changing parts often, adding a power adder, or want to tinker with it I would highly suggest going with a terminator x max system to run the engine trans, or just the terminator X if you are going with a manual trans. You can sell off the stock ECM and harness to help off set the cost. Now if you are going to throw heads and a cam in it, have it tuned local or via remote tuning once, and let it be forever, I'd rework my stock harness and use the stock PCM, it will work fine for what you are doing in that case.

There is a sticky in the gen IV internal engine section on LS1Tech, called Tusky's cookbook. Its a list of NA stick shift only builds with all 10.99 and faster in the 1/4 so well on their way or over your stated HP goal, OP I'd suggest looking over that thread for ideas as well. https://ls1tech.com/forums/generatio...or-builds.html

Re: Escalade motor
 

Agree 100% with this!

For that matter, don't get too hung up on having to modify the engine at all. When that stock engine goes into your c10, you'll effectively be shedding several thousand pounds of dead weight, compared to the Escalade. That's going to be a pretty solid kick in the pants right there. Just keep in mind, that a stock LS is already the equivalent of the best modded gen-1 small block of equal displacement.

Re: Escalade motor
 

Don’t get hung up on a set number, I’ve got a modded L99 6.2 in my 5th Gen Camaro. It’s got about 400 at the wheels and is still very streetable and a bast over all to drive. 600 is doable n/a but your going to give up nearly all highway manners for sure, I’d bet it will not be that fun to drive on the street unless your wide open and 6000+ rpms everywhere you go. Im confident you’d likely throw less money at a Maggie, whipple, or LSA supercharger. Then you can have way better drive ability around town and still have the ability to shred when you want. That said I bet you will find that 450-500 in an old truck is more than plenty. Even at that HP your going to have to do suspension, axle and brake mods to get it hooked up and stopped with out breaking anything or wrecking it. Here’s a little food for thought on the LSA: https://boostdistrict.com/products/2...w-supercharger

That’s an excellent start and you’ve got more than enough meat in that L92 to handle the boost. Drives mostly stock when your not on it and hauls ass when you want it too. Plenty of people have taken 5th Gen LSA ZL1’s way over 600hp.
