5.9l Cummins swap into a lucky Square Body

[1973 Chevy]

After a request by Hotrod to start up a thread on this swap in this section, I listened to him haha.

Basically I want this thread to show how much work it can be to swap a 6bt into a squarebody frame. Also all the wiring and other misc modifications that go along with it. Any questions I have or members have can be answered here also. I just got started on this so it will be moving slow depending on $$$.

First of all you gotta get yourself a squarebody of your choice, rip out the motor and entire driveline. Then find yourself a cummins. You will probably be better off if you find an entire running truck because you have the entire driveline with that. But I didnt take that route, I was able to find just a motor for cheap from a friend.

This is what I started out with: '95 12 valve

First thing I did was take off the front half of the motor to check and see if I had to tab down the killer dowel pin or not. Always check that when you buy a 6bt you dont want that falling out

Pulleys and such removed.

Took off the 400 bolts that hold on the timing cover

And theres the pin, I obviously have to tab it down

I am planning on test running the engine first before I do to much to it, but I need a set of gaskets to come in the mail first (oil pan, timing cover, front and rear seals) While I wait in the mean time I just started cleaning up the motor. Didnt think there was paint under there! lol

Were gonna hold you to it here TXOUTLAW. Be sure to hang out and check in frequnelty and offer up any help he might need. Of all the members on GMSB, you and Wildcatjason are probably the most knowledgeable on the Cummins swaps. So until we get one done live and a write up which 1973 hopes to do as he goes.... It'll certainly be benefit here. I know there are many members interested in such a swap.

I used TNdiesel power mounts an cross memeber . Worked really well for my swap. Scott is a awesome guy and very knowledgable about this . He's been doing this swap for decades ! There are a few things that will be difficult like your intercooler and mounts but if you get that done the rest in fairly simple . Do you know what kinda tranny your using ? On my forum ill post pics of my tranny mount I built for my getrag. If you want one let me know . The wiring is pretty self explanatory . Your coil hot goes to the injection pump 12v source . Then you can adapte the water and oil Eaither in the front by the water neck or the back . An the oil can go where the oil outlet where you feed your turbo there's a second plug off . Now your Eaither going to have to notch your frame so that the ac compressor for the dodge can fit or ! Go back to tn diesel and get the kit where it uses a 160 amp chevy alt and moves the ac compressor up ! Ill post a pic for you so you can see what I mean it's a good looking kit . I got mine running and the inter cooler in and on now I'm lifting and working on the other few electrical gremlins I got . An more heads are better that one ! Ill be here to help all the way like people were here for me !! Thanks alot !! Wildcat and hotrod helped me and I'm a fairly new member here ! So that means alot ! So I'm here for ya brother if ya need it . If you need my number just message me cuz it's hard to explain in writing some times haha

Thanks dude, I was just actually looking at tn diesels last night. Also I plan on running a dodge NV4500. I will certainly check out your forum and let you know if I need your number or not!

Just an FYI. You can run an air to water intercooler if you wanna conserve space. People run air to air left and right. I prefer the look. Just another option. The 4bt uses a water to air and you can get universal ones from www.frozenboost.com. www.autoworldmt.com is another source for cummins swaps and AC/alternator mounts. I wouldn't doubt if that is where Scott gets his. Don't forget the rear main while it's out. Cheap insurance.

 

[wildcatjason]

Autoworldmt uses the stock AC compressor.

Cool Video !!! Now we need some incab going for a drive !!!

 

[wildcatjason]

Which oil sender are you using? The one that came with the cummins or the one for the Chevy truck?

 

[TexasOutlaw87Cummins]

Chevy it's a one wire hook up . Put it next to the turbo oil line .
