Cummins Swap Square Body

[@21kitkatbar]

I basically have the same type of truck you have, crew cab chevy 84' 1 ton with single rear wheels, was also a camper special that had 2 battery trays, hydroboost brakes, and it was a manual so it had the higher trans tunnel, installed the cummins over a year ago and have tripled my MPG and increased my pulling power to boot. I have it straight piped for now but like you, i'm going to make it more comfortable to drive for long hauls. There are Mechanical cruise controls you could potentially install on the truck to make it easier for those longer drives.

[@Bloodbain88]

I got done with the same swap a few months ago. 1983 K30 dually 4x4. Went from a dog 350 getting 6MPG to having gobs of torque and getting 22MPG. I was lazy with the exhaust and stuck it through the hood. It is a little uncomfortable on long hauls especially if you're hauling heavy and can't use 5th gear. My 12 valve came out of a Ford F800 so I couldn't use the radiator, or fan, or intercooler, they were way too big. Used an aftermarket all aluminum radiator and dodge second gen intercooler. With some low pro electric fans. And a reman NV4500. It was a pain while doing the swap, but that first drive I knew it was all worth it. I didn't end up having to modify much either. Driveshafts fit. Pinion angle was right. Firewall cleared easy. Just fuel lines and throttle linkage had to be figured out, couldn't use the ones out of the F800. One thing I noticed after driving it for a while: I had gasoline fuel sending units in my gas tanks. When below half a tank I saw a steep decline in power. Turns out there is a difference between the gasoline and diesel sending units. The fuel return on the gasoline unit drops the fuel from the top of the tank and it falls and splashes. The diesel unit fuel return has a pipe that returns the fuel to the very bottom of the tank. I found that my fuel was foaming up and aerating the, causing a loss of power. I swapped them for the diesel units and that problem went away.

I absolutely love your truck! I have an 87 Suburban that I bought for 1k bucks. It's on 35s and I love it but it's got a tbi 350 and I average about 8 mpg just driving down the highway without pulling anything. Your video has inspired me to look further into a Cummins swap for it so I can pull my camper with it.

[@goingofftherails9877]

Jason thanks for watching. It's a totally different truck with a Cummins. It's capabilities far surpass what it use to be. However I always feel the need to tell everyone who is thinking about doing the swap, it not for the faint of heart and there are cheaper ways to get a pulling rig, but I still love my truck and don't regret it. And its got the cool factor!!

Really cool truck you've built yourself. I've got an 71 gmc that I played with the idea of putting a 12 valve into but ended up deciding in an 8.1l big block. Wasnt aware you had a yt channel, I first saw your truck on tfl's dude I love my ride

[@goingofftherails9877]

I started KZbin shortly after tfl's video , since there was so much positive feedback. I think your going the best route on your build with the 8.1 liter. I love my cummins but it was a lot work that you won't have with a v-8. Ive got a 72 and a 73 that I still would like to tinker with in the future . Good luck with yours !

I love your truck! I did a cummins swap on my 1986 gmc 3500 dually. It’s a 5.9 with a nv4500 2wd. I did a 3” body lift to avoid the firewall mods. I upgraded to a vintage air surefit system and no longer have the stock ac under the hood of you did that you could have room for your compound turbos. I did the lizard skin to try and deal with the noise but it still have to do the firewall and dash with dynamat and foam to quiet things down some more. Nice video and have a Blessed day!

[@goingofftherails9877]

Thanks Jason. Would love to see yours. Do you have any pics on instagram ? Im taking mine to my sons Ranch in Texas soon and I'm doing valve adjustment this week to see if that could help a little. I don't mind the noise that much but just trying to keep my wife happy. I did put a K27 turbo on a few weeks ago. Noticeable power upgrade

[@36browneyedman]

I am on instagram under supernaturalnut the truck is on there it’s white.

[@famousmidnight]

For anyone considering a swap seriously consider the 24 valve Cummins. Its much quieter than the 12v. As long as you have a good fuel system there's nothing wrong with the VP44. They will absolutely last 200k+ miles. My hat goes off to David for the swap though. Love the truck, I want a K20 Diesel swapped really bad. 8)

Getting ready to do the same exact swap on my '98 K3500 CCLB Dually. My donor is also a 1994 Ram. Bought a bunch of parts from Power Driven and will be getting started on the project by the end of the year. Still need to buy mounts and get a Dodge bellhousing and input shaft for my GM NV4500.

@@goingofftherails9877 I bought their 500hp Fuel Package, pushrods, 60lb springs, hot rod lift pump and their new Aggressor turbo. The K27 would probably be a really good match for those parts, but I wanted to give myself a little room to grow if I turned it up any more. We'll just have to wait and see how that combo works.

[@goingofftherails9877]

A 1st gen swap is still a great option. I do like my Power driven diesel fuel adjustment that the P pump allows you to "turn up the fuel" .With the flick of a switch I can almost make this truck fly. :)

I wanted 2 do something similar but I wanted 2 sit a 1986 Chevy crew cab body on a Cummin’s frame and leave the fire wall and dash and also leave the floor with interior from the cummin’s truck. Then weld the cab from the Chevy 2 the Cummin’s floor do you think that would be a easier way 2 do it.

[@jeffreyrigged]

that seems like way more work compared to a engine and trans swap and some wiring

[@goingofftherails9877]

I agree with Jeffrey Adams. Its tough enough to just do a engine swap, then add on cutting and welding to get the fit needed seems like a lot of work . Plus the GM frame and spring set up has a lot to offer in durability and easy modification.

[@xcelerator67]

Great build love the truck! My only question is how some people get the Cummins to fit without hitting the firewall? Then other people have trouble getting it in without damaging firewall? Just curious I'm sure it's a simple explanation.

[@goingofftherails9877]

good question Mark. If your truck is a 2wd , the driveline tunnel will be smaller, too cramped for the transmission . Secondly, what transmission you choose makes for a driveline interference. The NV4500 has the least amount of firewall interference than others, but I still had to beat the firewall upwards and the pinch weld to get it to fit. the steel is very malleable and does conform to a different shape with some work.

[@xcelerator67]

Ok thanks it totally makes sense....there's just something sexy about a Cummins in a chevy!

[@dante04srt]

Hope you're doing well and hope to see this channel grow! You mentioned having to enlarge the filler neck size to fit the diesel pump nozzle. How did you do about that? I just finished my swap and realized the nozzle doesnt for my 454 tank.

[@goingofftherails9877]

Hey DanteGTZ. All is well. I crafted a large tapered punch from some round stock and simply pounded the the light sheet metal into a larger hole. Didn't want to cut or file because I already hooked up the hoses. Work pretty good with a few rough edges. Good luck

been wanting to do a 6.7 and a 68rfe in a square for some time may just do a ly6 and 6l90e since gas is so much cheaper in all ways. i really cant find any info on how to hook a np205 to the 68rfe but i figure since you can hook a allison 1000 to one with a adapter you could the 68rfe since they both use a np271hd and will bolt from one 271 to the other.

[@goingofftherails9877]

Unless your going to use your truck for pulling something, I think a Built GM gasser is the way to go. City driveability is way better with a modern gas engine and transmission . I have a good 73 c20 I want to build some day with a 5.3

[@jeffreyrigged]

@@goingofftherails9877 well i do pull cars alot and plan to buy a camper but i think a gas truck would do fine with either for my intended purposes. since the old trucks weigh a bit less helps alot too. under 6k vs my 05 ram almost 8k.

[@PRSH8YAPROJECTS]

Put compounds on it and you will see a big difference with sound in the cab

[@brew_wy1375]

If you want compounds just switch to a Vintage Air setup for your AC. Moves everything under the dash, but you do give up glove box space.

[@goingofftherails9877]

Might just tackle that someday. I do think it would be worthwhile . I may have just smoked my turbo that I rebuilt, when I passed three trucks on the highway about 2 weeks ago. I flipped the switch on my AFC live when I went to pass, and I hit fuel a little too hard and my truck launched around the trucks but I went up over 40 lbs of boost... May need a new turbo soon?

Built, not Bought, Nice work. I'm curious what kind of difference your dual muffler setup made. I have a 1986 F250 with a turbo 6.9 IDI, and I have some drone at highway speed from under the cab (3" pipe with straight through muffler).

[@goingofftherails9877]

David. It did cut the drone to nearly non existent . The note from the tail pipe is kinda wimpy but ill take that over an annoying drone. When I put the second muffler in I welded v band clamps to most of the joints which makes it easy to change anything in the future. I just put a new turbo on yesterday (Borg Warner K27) and it was super easy to make the change .

Had to get creative on the driver side for my piping to miss my big block radiator . The passenger side is a simple 90 silicone boot but the driver side is a 45 degree silicone boot to miss the radiator. Used a 4" hole saw to make the entrance and exit holes for the piping.

[@goingofftherails9877]

@@hunterdias3080 I will add some video in my next posting of the latch and intercooler. If you have watched Gale Banks you know that cool dense air is the key to making more power, so naturally the bigger the intercooler the cooler the air. But I made the decision to leave the trucks front clip as stock as possible and not cut and fit the dodge radiator and intercooler into my core support. I know this was the best choice now because I left my radiator,A/C , wiring, mounts, grill, lights, everything in place. The intercooler fit great behind the grill and my cooling system still works great. Might be suffering some power loss because of the smaller cooler, but that's a hard thing to know without a comparable set up. Keep watching and I will explain in later video.

[@goingofftherails9877]

Jason. My Truck is registered as a farm truck. I have about 50 head of Yak and derive income from them, so I am exempt from Emissions. However I did go and talk to the emission people about a swap before I started. To my knowledge , if the engine is from a truck that is a newer model and your truck is similar in gvwr , then a swap is allowed as long as every emission related part is transferred from the donor truck to the older truck.

Cool truck! Im a dodge fan but I have a 1984 chevy c30 I'm gonna put a cummins and a 6 speed into one day trying to find the 12 valve engine and nv5600 trans on gonna throw in it

[@goingofftherails9877]

I would love to have a 6 speed trans as well. The 5 speed does well with 4.10 gears but I am going to switch to 3.73 in the near future and that may be when I'll wish for an extra gear

[@oldcroneysgarage9739]

@@goingofftherails9877 have you looked at a g56?

[@goingofftherails9877]

@@oldcroneysgarage9739 I haven't ever seen g56 case out of a truck to gage size. My guess is you would have to do more drive line tunnel mods to fit a bigger case. My shift lever for my 4x4 T case is very close to my bench seat right now. I guess an option might be to move the engine closer to the radiator and use electric fans. Would be worth checking in to.

[@oldcroneysgarage9739]

@@goingofftherails9877 a guy I watch on youtube put a g56 behind a 12 valve in a dodge but I'm pretty sure it's different for chevys. Might go check out v belt and son on youtube he works with a lot of 12 valve engines. I'm might be looking at converting my 1982 chevy c10/k20 to a Cummins with a 6 speed mines a single cab 4x4 with a Cadillac 425 big block its hard to find parts for a Cadillac 425 any where

[@goingofftherails9877]

I have seen v belt. Thats a nice set up he has. I learned how to drive and got my learners permit in a 1978 Fleetwood Broughm Caddy. It was pink!!!! and had a 425 ci v8

[@headlesnorseman701]

the cummins weighs that much more than a cast iron big block? thats insane to me lol. i guess thats why those motors last forever. its basically a locomotive

[@mattkenaston7180]

Great video. I'm with you on the simplicity and ease of repair on the older trucks. I'm getting ready to put a 4 door square body on a C50 chasis. I would like to do the cummins swap and your video has some great information. Thanks! BTW nice footage of the needle hwy. you didn't pull the caboose up there did you?

[@jeffreyrigged]

i have a newer cummins in a 3rd gen ram its not quiet either.

[@williamwhitted2490]

Variable geometry turbo. Your welcome

[@lanceroark6386]

Go green and Cummins swap an old square body.

[@goingofftherails9877]

heck yea! I drove 3 hours up into Wyoming with my trailer and towed home a 94 Chevy Truck . I averaged 15 mpg.

[@jaceinlow8980]

Great truck but needs a new headliner

[@goingofftherails9877]

paisley makes me feel like my truck has a little bit of class!

[@americamike9214]

Great build man! Check out my Cummins swapped blazer!

[@goingofftherails9877]

Nice job on your build . Are you using the 24 volt Military electrical system or switch to 12 volt?

[@americamike9214]

I rewired entire truck with new fuse block. It’s a 12 volt system now
