LS Swapped Winnebago - Part 1 - Mopar to Chevy swap

More projects? Sure why not. Been keeping this under wraps for a bit, but here we go. Took out the 440ci big block Mopar and swapping in a 6.0L Chevrolet LS motor.

[@thesunflowchannel1995]

Most people just take out the motor and junk the body, but you're here junking the motor and keeping the body haha.

[@StationroadRatrods]

I’ve never met anyone who actually *wanted* a 440

[@tdp2612]

We have hit peak 'LS Swap It' now. All other swaps must bow down to this behemoth.

[@BobPegram]

LS is a great motor and practical, with enough low end torque. Me, if less grunt is necessary, I prefer a Ford Coyote or better, the Voodoo! I never thought I'd see the day when one of the "Big 3", now 2, would make a 4 cam 32 valve V8!

[@stampeedvalkyrie]

I think you'll find many takers for that 440 so long as it can be rebuilt. The 440 and 727 trans were an excellent combination. I have a buddy who bought one of these for the 440 and ended up putting it in a 440 coronet.

[@shawnvanderdoes9823]

This is a great build, hope to see more.

[@canuckfixit7722]

I gave this a thumbs-up because usually these old campers are junked for the big block motors (reference to Roadkill and the General Mayhem). In this case, the motor was junked for the camper itself. I watched all the subsequent videos right to the full road test. Great job!

[@robsvideos13]

brake rotors are readily available thru JC Whitney - bought two last summer - P/N 120.67011 you shoulda left it original with the 440-3 - all it probably needed at 120K miles was a timing chain and gears. Factory HP rating on the 440 was 210 and I've read that they're way underated and it was more like 265 and almost 400 ft lbs of torque even at 8.2 compression. My Titan gets about 8mpg.

[@richardprice5978]

why so low? the car engines and lite duty trucks got at least 350 HP out of the 440 and the 6 pack was rated at 475~ hp my stock unmoded version 1969 G-coded engine stock is 300 + hp sorry i can't remember the toque numbers right off the top of my head right now . and mopar did make a turbocharged version for " heavy duty " / pumping uses mostly to help pass emissions

I'm still amazed how small even though it's a V8 those Motors look compared to the RV and it still pulls them very well amazing.

[@MrZayne8]

Very cool project. Love the old Winnies. I've only seen two that were painted to shine. My '71 Chieftain will get a similar treatment down the road, but the venerable 413 big block still runs strong for now. The old Dodge Motorhome chassis can be a PITA to get parts for. A later model axle & brakes might be a worthwhile swap.

[@redneckswitwheels]

Truly awesome man! I love it

[@southjerseysound7340]

Neat project and I too never knew they had a shine lol.It must've spent a lot of time inside,

[@richardcline1337]

The '78 Allegro my late wife and I used to have could get between 7 and 9 miles per on the highway as long as I kept my foot off the rear bumper of the guy in front of me. That Chevy 454 was really strong and the guy we bought it from had run dual glass paks out just in front of the rear wheels so if I pushed down on it to get around somebody or hit a bad hill the sound was wicked awesome!

[@haroldfitz5146]

My 74 29' Custom gets 7-8 mpg with the 440. Maybe because it's only got 39,000 miles. Very interesting project though. Goodonya for taking it on. - Harold

dude great sense of humor lol love it

[@mworld2611]

LS swapped RV, I'm subbed! I wanna see how this goes.

[@xozindustries7451]

The problem with the LS swap is the torque on the Chrysler is off idle, and the LS is at 4500 rpm, so you have to hold it by the throat at all times to keep it rolling up hills, and the Overdrive trans will need the rear end gears to be changed to 5.14’s or 5.36’s. Cool deal though. I’m swapping a 502 with the vortec big block heads and EFI / 4l80e trans from a 1998 Chevy van. I can’t wait to see what the mileage will be on the LS compared to a 502 with 600lb ft at 1800 rpm.

I had a client with similar issue with brakes said he used front rotors off of a 2004 3500 4x4 dodge truck. Your Hydra boost is Gm anyway so I would use the Gm pump and bracket. With the a/c I would update the compressor with the newer one you could do it with brass barbs and clamps all a/c hose is standard fitting sizes inside.

[@tylerangieslayton7455]

Chrylser 440 = 480 ft. Lbs @ 2800rpm... That Ls cant do that at 7000rpm but the reliability and availability of the 6.0 is what makes it make sense. Nice work!

[@johnsaum1260]

it takes bottom end torque to move that motorhome. some well chosen parts from 440 source would have been easier and better.

[@RUSTYCHEVYTRUCK]

Easier yea, better not

[@mikeg3529]

For the rotors, try and see if you can find rotors that will work with that lug pattern. Cause yiou could probably drill out those rivets holding that spacer/adapter and fasten them to new rotors with nuts and bolts

[@Impactjunky]

Had boatloads more performance potential with the Mopar 440

[@timlocher4829]

Because with a rebuild, a bunch of other work, youd make similar power get worse gas mileage and still be hooked to a 3spd unlocked auto sounds like a good sound cash effective plan

[@Impactjunky]

@Tim Locher Dropping displacement in a large vehicle is never more efficient. You'll have to lay into the throttle so much farther with a small block that it will completely negate any potential efficiency gains. A small block chevy has nowhere near the power potential that a big block Mopar has, only way you can get close to the 440's ball park is with forced induction. And top gear in a Torqueflite is the same ratio as top gear in any other common non overdrive transmission, my 68 Roadrunner with a Torqueflite 3 speed can get 20 plus MPG highway. If power and efficiency are the goals then just rebuild the better motor that the vehicle is already designed for and add a gear vendors overdrive.

[@FuelInjectionSucks]

The price of the gear vendors is going to surpass the entire project, including the price of the motor home.

[@Impactjunky]

@Fuel Injection Sucks Damn you're right, I was under the impression they were more affordable than that. Looked one up and the model for a motorhome 727 is about $4,000.

[@JohnnyAnderson1]

I would seriously consider throwing a small turbo on that to help with low end torque. That thing is gonna be shifting like crazy especially on big hills or with a strong headwind.

[@brendenw.7312]

Everyone is over here saying that the 440 is a god, meanwhile my 1973 Winnebago is awaiting an engine swap because that 440 decided to spew its rods on the highway after 33,000 miles.

[@w41duvernay]

Make sure you put a truck cam in it. Long tube equal length headers would help as well. Primaries need to be 42" long, I would suggest getting a hold of an Old Headers by Ed catalog, and read the whole thing.

[@joeinmi8671]

Wont get the mpg or torque without the 6.0 intake and fuel injection. A few guys have done 12v cummins in these. The nice thing with the gasser is you dont have to change the rear end gears. That was the biggest hurdle for the diesel swappers because they had to also install a gear vendors OD unit to keep the rpms in check with the diesel or drive slow.

[@FuelInjectionSucks]

It's going EFI. Spoiler alert.

[@mopartshemi]

OHH THOSE BRAKE ROTORS That's a first gen dodge brake caliper can tell by the clips they are super famous for caliper clapping over bumps, Im thinkin a D350 500 or 600 will work for rotors order them and try em out worse comes to worst return them you have to pull the adapter off

You may just have to find a front axle that's the right width from a truck or something though.
