Cummins 6CTAA8.3 in a Ford Truck

[C-Series-Man]

I showed a couple of pictures in a past topic and told a couple of guys that I would post a couple more pictures about my project. Here is a picture of the 429 that was in my truck before I decided to try and put a C Series in it.

Once I got the old engine out, it was time to mock up the new suspension and engine combination.

After lots of plotting and planning, it was time to make some suspension and engine mounts.

Next I started to build up the engine.

After a couple coats of paint:

Next it was time to clean up and mount the Fuller 9 Speed Transmission and twin disc 14 inch clutch.

#ad


Now it is time to finish up the front and rear axles. I have already put the lockers in the Dana 60 and Ford 10. 25. All that is left is finish the 4 wheel disc brake conversion and make some drive shafts and then the running gear will be complete. Lastly, I have to put the sheetmetal back on, put the floor back in the cab, rewire the truck, and put the interior back in. I am looking forward to seeing what I can get out of a C series! If you have any questions, feel free to ask.

SWEET!
LOL when I saw the firewall and floor mods! That is a BIG engine.
Nice fab work, too.
What are you planning on doing with it when it's done? Mud? Rocks? Cruising?

Thanks for the pictures! It is interesting to see what is possible when someone puts their mind (and not just a little time and effort) into a project!

Good Luck!

Can you BOMB the 8. 3? Not that you will ever need to, but just curious. What turbo is on the 8. 3?

I bet when you get it finished you wont even need to touch the gas pedle just shift the gears. LOL

I think the 8. 3 comes with the HX 40. I have herd of Piers bombing 8. 3's to 1000hp #ad
for marine duty. All tehy are is just a big 5. 9. So all the same ideas on bombing will work, just add more fuel and air.

Your effort is greatly appreciated. What a prodject. The 8. 3 C motor is nothing short of a horse. Nice touch on the transmission also.

Keep us updated with some pictures.

Cheers to your work - a fine fabrication. Ingenuity is one of the many things that makes this country great #ad

ATTA Boy,,

I sure would like to do a project like this one. I don't think you will need the BOMB ferry to come visit, with the looks of things it comes BOMB'd. . #ad

I want to see the finished product!!!!

Thanks for all the kind comments. I intend using this truck as a daily driver and trailer puller when I finish.

Any chance that you'll have it done by June 9th and could come up to Muncie, IN for our event here ( http://gltdr.org/muncie01/june9.html )? It'll be an all brand diesel event and I'm sure you're truck would be the hit of the show!! I'd love to see that baby hooked to the sled!

Hey, C-Series, awesome work, man ! Hope you can make it to Dave's Diesel Thunder in Muncie, June 9th & 10th, Muncie, Indiana !
Like Steve says, I'm sure your truck would be the hit of the show.

 

[C-Series-Man]

Don't hold me to it, but I think I have a fair shot at finishing it up by then.

I am forced to use the same style exhaust retarder as the B does. The ISL compression brake will not easily fit. I have checked. I think that it is possible to make it work. I just don't want to spend the time as this point.

Wow! Dittos on all the comments. Nice! You've got me curious. I had a '76 Suburban that I was going to do an ISB conversion on. Why didn't I do it? I guess I just wimped out. Lots of conversions to mess with. And it would have been easier than what you've got, because Cummins at one time (maybe they still do) had conversions kits to put the ISB in any of the Big Three light duty trucks. They had the engine mounts, trans adapters, etc. So, kudos and good-on-ya!!!
Well, you got me to thinking again. I don't know how you manage to work on your project and answer all of our questions here, but if you could spare a little, I've got a few.

1 a. Cost of the motor. New or used. 12 or 24 valves. Mechanical or electronic pump.

b. Cost of the transmission and transfer case set up. Cost and details of fab work for these. Where are the shifters going to be? In the big rigs, the shifter is right on top of the trans, like I saw it in one of your pictures, so either you are going to have bucket seats, and the shifter will be right between the seats, or else you'll need to rig some linkage.

2. More details on the frame work. you mentioned how you beefed it up, but could you be more specific. If I do my project, I'll find a pre-1980 GM crew cab duelly. If I can beef up the frame without too much trouble, then I will. But I think I'll lean toward a new frame from a 2 1/2 ton, or a Kodaic/Topkick, and shorten it.

3. You're going to have A LOT of torque. Is your driveline going to hold out? It seems to me IMHO that something sometime is going to give.

Thanks in advance. If you don't want to post it here, please email me.

I'm moving to Deleware next year. Maybe I'll have to come down there and check this be-yute out!

First class C-Series-Man. I am also interested in how you dealt with setting up the transfer case with the Fuller transmission.

 

[C-Series-Man]

The used engine cost is whatever you are willing to pay. I found used/rebuildable mechanical C's for around a grand. I would also plan to spend that much more to rebuild it - new liners, pistons, rings, gaskets, etc. The biggest thing to look for is a good injection pump. My engine spun a rod bearing and chewed up the crank. The seller threw in a new crank as part of the deal. The transmission ran me 350 bucks. This was a pretty good deal, but not hard to find. The transfer case is a little harder to find. It just takes time to find one for what you are willing to pay. The cost of fabrication is hard to quantify. I enjoy doing things like this. I spent around 75. 00 bucks for all the steel and probably that much more in saw blades and welding gas. If you have to pay somebody to do your fab work for you, it will quickly make the project very expensive! Besides, that is the part that allows for creativity and some design fun. The main thing is to not create any artifical stress concentrations. Most any frame is strong enough if the stresses are channeled properly. Make you mounts over an extended portion of your frame, avoid point loads, keep mounts near suspension points, use gussets and braces where needed, things like this help add to the strength. I don't think that the large amount of torque will be a big issue. The weakest link in the system will be the intermediate driveshaft between the transmission and the transfer case. Unless the truck is heavily loaded, I think the tires will simply spin. Of course I will have to drive with some common sense, but I think that everything will be ok.
The question about how to connect the huge yoke on the 9 speed to the transfer case is interesting. I took the yoke off and machined it to recieve a custom carrier. I bolted a flange yoke to the carrier. It is not that hard to do, you just need a lathe to keep everything centered and balanced.
The shifter came out about 2 inches further back than a stock one. I think this will be ok, I can bend the shift arm if needed. I am planning on using a couple of air ride seats anyway. The floor will be open between them.
Any more questions?

This had probably already been asked, but what t-case are you using? A mid 70's Ford divorce mount 205?

I really wish you hadn't posted your (relatively inexpensive) prices, I've been wanting to do something like a '91 Chevy SRW Crew Cab (last year of the older body style w/solid front axle). #ad

Your exactly right about the transfer case. Divored NP 205
