LS swap into GMC motorhome
- Thread starter steven47
- Start date
Think about this. A drive shaft, 1 1/4" in diameter, going in one side of
the oil pan, and out the other. Then, think about the crankshaft, rods, and
oil pump. Clear those hurdles, and anything is possible given enough
determination and money.

Steve,
It just takes time to figure how to lay the tube inthe pan and tig weld the
pan.
I have advised some on how to do it.
An Allison tras is an Allison Torque converter.
where all the vains are brazed on ad the ccenter bearing is a roller beari,
not a bronze bushing.
Just like people do not know the diferance between a Japanese and Chinese.
They both have nese.

If I understand what Jim K was saying it’s only the torque converter, meaning it’s still a three speed TH-425.
That it, Jim?

Well, if you want a 4-5 speed, it will happen.
Meanwhile lets get the LS planted in.
The gain of the 5 speed is not going to give you a big erection.
Ask Hal St Clair, I believe he put one in and used a transfer case to
accomplish that.
Hal is a very talented craftsman and mechanic so he does these things well.
If you cannot do it well, you'll be on the side of the road.

Steven(if that is your name),
1st, it is always nice to know who we are conversing with, and from where you are hailing us. For that reason, we kindly suggest that you set up a signature that provides us with a name, location, and the year and model of your coach. It simply helps us relate better to you and your needs.
2nd, regarding your LS swap questions. The subject has been discussed previously by members who do not visit as often as they used to. You might try searching previous messages on the forum.
LS swaps were also discussed in several of the GMC motorhome related facebook pages. There are also photos showing some prototyping and the headaches encountered. So far, nobody has successfully transplanted an LS due to the complex issues that require major alteration. The bottom line is that with enough money, anything is possible.

Welcome to the group, family, cult, asylum.....
You are new here and that is not a problem at all. As was suggested, please create a sigfile. As it looks like you are working the forum, go to
and scroll down. Please fill in: A real name because we like to know who you are when we meet, A bit about your
coach (model, year and major mods) and a geographic better than NW. This is an amazing group and you will get real assistance here and good
information, but we have to know what we are dealing with from the get-go....
I am not sure what you hope to gain with the LS motor. The Olds engines are know for both their longevity and reliability. In our use, those are two
really good things. If you try to cram in any engine not designed to go with the TH425, you are in for a major program. Given the NW in your current
alias (that can be changed easily by the way), you are not close to Michigan. If you really want to pursue this, you really need to meet Dave Lenzi.
He has done a number of 8.1 installations. But, you should understand the this man is a true Grand Wizard of metal work. He does make oil pans with
a pass for the right drive axle. It misses the crank throws by about 45mil (Not mm) on each side. He also modifies the RFB (Rear Face of Block) so
it can bolt to a TH425.
Do you already have a coach? If so, tell us more.
In any case, you should look up the Western States rally that will be in October and plan to get there. Coach or no, it you have interest at all you
can learn more standing in one place (try to keep you mouth closed, because it is easy to be overwhelmed), than you will learn by trying to read every
thing that you can find.
In any case, Welcome.

I'm not sure what an LS conversion would accomplish. Granted, it is a more modern engine with a modern management system, but I don't think it would
work well in our application.
I have a Chevy 2500HD with a 6.0 LS in it. The truck is empty most of the time and I would guess weighs in the neighborhood of 6500 lbs and while it
is a hot rod, it still only gets about 12 miles per gallon. Put that engine in a 12,000 lb vehicle with 30% more frontal surface area and it will
probably get the same, or worse mileage as a 455 olds.
There IS a version of the LS that is used in a four wheel drive Saab version of the Trail Blazer, that has a tunnel through the oil pan for an axle
shaft, that might bear some looking into if someone REALLY wanted to do this.

I would be more interested in a 6 speed transmission than the 6.0
We just traded our company 3500 that had the 6.0 for a diesel because we needed more grunt.
Just say’in.

My first engine swap was in a 1938 Olds. Pulled out the flathead 6, and put
in a 303 Olds Rocket. Went well, but the stock brakes, drive shaft,
differential, didn't like it much.
Second was a backwards swap. Had a 1946 Ford Deluxe 4 door with a 1958
Chrysler Hemi in it. Locked spider gears, Ford 3 speed truck transmission.
Pulled out the Hemi and the locked rear end, and Built a full race Ford
flathead for it. Much better.
Third was a 1951 Chevrolet. Pulled the 216 in-line 6, and replaced it
with an Olds 324 v-8 and a B&M Hydro-stik 4 speed automatic, along with all
Pontiac running gear.
So, I am not a stranger to engine swaps, but, experience has taught me
quite a lot about them. Proceed with caution is the best advice I can give.
Some of them don't turn out well.

Had an 08 3/4 ton suburban with the 6.0. Hated the darn thing. Horrible
fuel economy and constant trans shifts. Super annoying.

I think a swap would be cool to do but like the others ive been around the block a few times building and swapping things.
If i was looking to throw "the bucks" at this motor set up id be looking at a pro-charger like a Paxton....rebuild the motor specifically for it and
hope like heck the drivetrain can take 500 or 600hp.
The majority of the time its always the same...make power, break parts...fix said broken part with something stronger then fix the next broken part
etc till everything has been modified and you are no were near the place you started.
Moral of the story....do it all or do nothing but its sure damn fun to try.

I think the biggest thing I heard from the retired HydraMatic folks at the Great Lakers rally, is how they went to stamped parts from cast and machined.
We had a lot more headroom when we were dragging 5 to 6,000 lb cars around.

Not a good strategy for a motorhome. Unless you have REALLY good towing insurance. :twisted:

My old B&M Hydro-stik was based on the pre-1953 Hydramatic Transmission.
Cast iron case, and planetary gearset INSIDE the torque converter. It had
4 forward speeds. 100% reduction in 1st, 75% reduction in 2nd, 50%
reduction in 3rd, and 1-1 in top. B&M said that it was good for 1000
Flywheel horsepower. I never broke it, but I sure did break lots of stuff
downstream from it. When it shifted gears, you could look on the pavement
where the rubber was laid down and tell where the shift points were. No
breaks in the rubber, just the density of the patch changed. It would jar
the fillings out of your teeth on wide open throttle shifts.
Just what you DON'T WANT in a family motorhome.

Are our stock 455s and 403s lacking on power or endurance in some way? I have two coaches with one of each engine and they have always done whatever I’ve asked them to do. I want maximum reliability from them - not maximum horsepower. The engine and drivetrain are already working at a marine/industrial duty cycle when going down the Interstate and I sure don’t want to ask the driveline to eat anything additional by putting in some monster engine.
FWIW, I already know the answer to my question posed above but I am curious about peoples' motivation for going through a bunch of machinations to graft in high HP/high torque engines and drivelines when the existing ones seem to work fine.
