I'm putting a 6.1 Cummins stroker 24v with a 7100 pump and fitting compounds at the moment. In a 74 quad cab dually. Fits like a glove. G56 trans. 373 gears. To haul my race trailer
I had to massage the fire wall a bit with a hammer right at the exhaust manifold. The modification to the core support were solely for the the intercooler.
Thank you. I used the slave master setup from a Jeep Cherokee can’t remember the exact year. Drilled a new hole in the stock chevy pedal and removed the spring. Power Driven Diesel and Southbend Clutch were a big help with parts selection on my build.
Looks great! All of these Cummins swaps seem to be pretty loud in the interior, but I’m probably going to do the same thing to my 89’ crewcab squarebody 4x4. Thanks for the motivation.
I have used the stock AC systems but it's a snug fit, heat wrapped the exhaust pipe & sprayed the firewall & ac box with lizzard skin b4 applying a foil sound deadening all the way under the cab & inside, you have vac for the inside controls The aftermarket kits all fit inside but are visible below the dash to kick as well as your glove box becomes super small but prob your best bet unless you score a parts truck. Plan is to install a suburban rear heat & ac unit under the 3rd seat in the 6 door.
All other Cummins swaps I've seen had the motor mounts moved back on the frame to clear room for the intercooler and Rad up front. How were you able to bypass this?
I had to modify the core support a little for the intercooler but honestly the cummins fits in a squarebody better than a second gen dodge. I will look to see if I can find a picture of my core support.
The 12 valve doesn't take much. regular starter stuff obviously. Then for the fuel shutoff solenoid you need 12V pull i came from the starter solenoid for this and 12v hold i used the coil power from the squarebody for that.
@@brianuerling4830 it looks nice!!! My 75 K5 Blazer is supposed to be yuba gold also. I may repaint my K5 the original color. The color looks even better aged.
I just dragged a 1 owner 86 crew dually out of a barn. what size wheels and tires you go? i am looking to do something very similar with wheels and suspension.
Those o square body models were produced from 1973 - 1991 except the half ton & three quarter ton regular cab pickups were done in 1987, & the one ton regular cab pickups were done in 1989.
@@brianuerling4830 & the square body medium duty models which are those bigger size trucks with the same cab design but smaller rear window were produced from 1973 - 1990. The square body pickups were the first generation Chevys & GMCs to have an optional bigger cab which was the crew cab like that one there in the video & they were introduced in 1973 which was also the first year for the square bodies. Unlike the crew cabs today which are available on half ton models with short boxes, the square body crew cabs on the other hand were only available on three quarter ton & one ton models & only had long fleetside boxes.
@@brianuerling4830 fun facts, in 1987, the C/K series were dropped & renamed R/V series to make a distinction between the square body models & the upcoming next generation C/K series pickups for the 1988 model year which were the OBSs because both of those body designs were gonna be in production at the same time which lasted up through 1991. The one ton regular cab pickups were the only models with both body designs produced at the same time which happened from 1988 - 1989. From 1988 - 1991, the OBSs only came in regular & new extended cab pickup models at the time because the crew cab pickups & SUVs with the previous square body design were still in production through those years.
@@justinraystyles3537 Thank you. Bought the truck with no engine. I wanted decent fuel mileage and good power. It was the best option for my situation.

As a longtime fan of old Chevy duallys, Cummins engines, and cat beasts I found this video to be excellent👍👍

That will be awesome!
How far away is the engine away from the firewall & did you modify it & or the core support to get the mechanical fan to fit? All mine are 4wd

Truck looks amazing. How did you hook up the clutch? I have an 83 automatic Dooley and I want to put a five speed manual in it with a 24 valve.

Awesome truck and great advice. Go get something out of a field and make it your own ❤
Thanks! Way more enjoyable than buying new.
WOW was für ein tolles Ding🤙👌👍
Cool truck gay engine swap
Yep ruined.
I’d love to buy this truck , for sale ?
Everything has a price. I would listen to an offer.
Looks great! All of these Cummins swaps seem to be pretty loud in the interior, but I’m probably going to do the same thing to my 89’ crewcab squarebody 4x4. Thanks for the motivation.
Thanks. I used a lot of sound deadening. It’s not that loud.
@@brianuerling4830 I’m glad to hear that. I’m sure that helps. Thank you.
does it make for such a better mileage?
@@hirthirthirt1693 yes it gets around 15 mpg now compared to probably 6 before.

I just keep putting it off, and driving with the windows down. I got rid of the vacuum pump so I am pretty much pigeon holed to the aftermarket.
subscribed. love trucks like this old round eye square c30 with cummins. can't wait to see more videos of squares on your channel.
Thanks my nephew is building a lifted version maybe I’ll do a video of it.

What size tire did you put on this truck?
Love the truck. Looks great low like that. I have an 86 and was wondering if I had to move the tunnel if I'm using an auto ?
I doubt you would for an auto. This G56 is hug so I had to raise it my tunnel.
Nice truck man.
You gave me an idea what to do with my 88 R30 dually ,I finished my c10 1974 and my 92 gmc sierra and my next project is the R30
Thank you, have fun with your project and let me know if you have any questions.
Don't do a Cummins
@@jesses.7107 What's with all the hate?
@@brianuerling4830 Cummins swaps are gay
@@jesses.7107 yeah who likes more power, fuel economy and longevity. Totally ruined.
Nice truck. How much did you lower it and what kit did you use? What size tires are you running?
Thanks. 6/8 western chassis kit.
Wat all did it take to wire up rhe engine lookin to do the same to my 87 squarebody

What’s the original color on that called?
Yuba Gold 53L

@@armygreenfj3924 Thank you!
Is this particular motor easy to keep up as far as maintenance, pm’s etc?
Very easy.
What kind of fuel milage can you get driving unload?
It’s around 15 but I drive a pretty aggressive.
Absolutely love this build. Good work sir.
Awesome! Thank you!
What wheels are those?
16” alcoas
what size tires? Perfect stance
I just dragged a 1 owner 86 crew dually out of a barn. what size wheels and tires you go? i am looking to do something very similar with wheels and suspension.
16" alcoa wheels
What size tires, they look good.
Did you say what suspension drop it has, or did i miss it?
It is a Western Chassis 6/8.
Not much rain I guess no wheel wells 😂☔
I have drove in the rain on the interstate. Didn’t seem to harm anything.
It was cool seeing the before pics.
It was quite the turd.
Thing looks sick
Thank you
