Hey guys, scrounging around still for a 94-98 12v. Lots of 8.3 out there in the yards ive gone through, the guy running the place said the 2 engines have the same bolt patern on the bellhousing? This gets the wheel to rolling, if this is so why doesnt anyone run the bigger brother cummins? Sure its heavier but should make much diff. exp. to you pullers that hang wieght way out front. Just sooo many CID. About 500 rather than 360. Just saying if all the same things were done to a 8.3 that we do to a 5.9 wouldnt ot re-open a whole can of worms???? Any thoughts guys

Ps. it only looks slightly larger on the outside diamitions, maybe no wider, prob, slightly longer.............

Heres the dimensions I got from our generator at work:

Length 42" (timing case to bellhousing)
Width-27" (timing case was widest point)
Height-36" (valve cover to bottom of oil pan)

From Cummins.com on the QSC brochure:

L-44"
W-31"
H-42"

With a wet weight (with oil) of 1,594 lbs . The B wieghs approx 1100 lbs.

Looks like the dimesions will vary slightly based on oil pan style, timing case, accesories, etc.

Knowing how much power can be had from a 12V P-pump B series, I am sure that the same could be had from a C series.

I just don't think there are the performance upgrades available for the 8.3 that there are for the 5.9 and I know in medium duty applications the 8.3 doesn't like to spin very fast so I don't know if it would hold up in a high performance situation. An IH DT-466 would be a much better option in my mind since it pretty much set the standard for diesel performance over the past 30 years.

i happen to have the 2 engines sitting together. the 5.9 looks like a toy.

thought about putting it in a 2nd gen for pulling but as soon as someone made you open the hood youd be kicked out. most would knotice the injectors on the opposite side of the head.

It was just a fun thought, after hearing that the bellhousings were the same. Are you pullers set to a CID limit? If so dont see how the fords would be in the same class. There about 445ci i believe to our little but mighty 360! I think the 8.3 would be right at 500ci or so.... ya because the viper is 8.3 and i believe thier 505ci, later Ryan

All of the 8.3L C series engines I have seen have the injectors on the left (intake) side of the head. These are engines equipped with a P-pump. Don't think I have ever seen a 24V 8.3, but I would assume that the injector is in the middle (dead center) of the head.

Got to admit it sounds like a great idea, the great efficent design of the ol cummins but another 140 inches to play with. Wonder if its the same p-pump just set up with larger internals to flow a bit more fuel? Not sure either if a 24v was made but i know where one is in a large truck and it will flat run in stock form. 3-4 inches longer little wider and what 400-450 lbs heavier, sounds perfect for a pulling truck. Or a drag project with it set back 6-8 inches??

In sledpulling the engine must be from a 1-ton or lighter production vehicle. So it wouldn't work.

I'd take a 5.9 for racing, but a bombed 8.3 might make an interesting puller.

I had 2 Case MX270 tractors and they both had 24V ISC Cummins in them. They were a little bit different because they used a Cummins CAPS pump, which is not a true rotary or inline pump. They were really great engines and had a TON of torque. TST made a power module for them, but I never had one. Didn't need it. These things would make 300 PTO horsepower all day long and around `1500 ft/lbs of torque. They also wouldn't 'lug' down like a conventional mechanically governed engine. The ECU would just keep fueling these things and let them pull down to about 1750 rpm and hold it there no matter what you did to shift it. I tried to lug one down once and at about 1680 a bunch of alarms went off and the tractor shut down.

TST Power Kits can be used on any Cummins 6BT5.9 or 6CT8.3 series engine equipped with the Bosch P7100 style fuel pump. On-highway kits are available to 230 horsepower and 605 lb.-ft for the 6BT; and 325 horsepower and 920 lb.-ft for the C8.3. For the C8.3, off-highway competition kits are available with up to 450 horsepower and 1000 lb.-ft for the 6BT; and 525 horsepower and 1800 lb.-ft. for the C8.3.


This is from TST website. Those are some nice torque numbers for the C

i dont think a ram could handle that much torque!

Sure it could, if not my little 1/2 chevy with the Now fully boxed frame could!
