The Cummins K's were rare in any truck. Very large and heavy, expensive, and not fuel efficient. They did, however, make more power than about any other...
Bob, Of course, Cummins had began offering their NTC line with up to 475 horsepower, achieved from using not one, but two turbos. What does 475 hp @ 2,100 rpm...
The 1977 GMC Salesman's Data Book lists the Astro model DL9502 standard equipment as being the KT-450 (434 h.p. @2100 r.p.m., 1326 lbs./ft. @1500 r.p.m.) with...
Hi, It is conventional wisdom, in a way, to say that the better the engine's torque rise is, the less gears in a transmission that you need to maintain the...
Although it has been a while since I posted a message on this forum, I want to wish each of you a Christ-Centered Ressurrection Sunday and many more miles in...
The Cummins 19-litre has a large following here in Australia for triple road train work (110+ Tonnes). Atkinson 3800's & Kenworth SAR's got KT-450's in the the...
Hello, b20paul, A SST 1107 was a seven speed. I think that ST stood for split torque? That transmission had two lows and two reverses included in the shift...
Hi Steve, Yes, SST = Spicer Split Torque, which is basically Spicer speak for Fuller's Twin Countershaft. I'm familiar with the 6+1 boxes, a 6 speed box with...
I will have to agree with you on the SST ten speed being a good gear box, but when repair's are needed, they are more complicated, and parts are way higher...
Are Spicer parts still expensive since becoming part of TTC? The 6 & 7 speed Spicers would be bad in a cabover with the gear lever stuffed between the seat &...
Hi, Do you have any good (not bad, please) thoughts about the 8V-92 Jimmies? The only ones I favor are those that utilize turbocharging (because I like the...
Hi, For those of you who like rare Cummins diesels, on YouTube there is a video of a 1952 American LaFrance 700 series fire engine powered by the VTF-555...
I can't find any information that says the VT-555 was going to be available in the 1980 Brigadier/Bruin, but the VT-225 was supposed to be available in the...
Hello Group, I got the chance to go to the ATHS show in Huntsville Alabama Friday, And it was awesome. I made 165 pictures, my wife made 259 pictures. I just...
A.T.H.S. shows are always fun. The first generation GMC air suspension was similar in many ways to what was used on GM coaches in the 50's. The really...
Most of you have probably heard by now, GM has announced that the Kodiak and Topkick will be discontinued in July. Production of the W Series and Isuzu NPR...
I've learned that the SST-11 (Model SST-1211) is a similar to Spicer's later 6+1 boxes, but the splitter evenly splits each of the six gears. It has the same...
The natural 555, natural 903, turbo 903 (& VT-300/320/350) were very popular here in Australia. 555, 903, VT-190/210's were fitted to the extraordinarily...
Sounds like a great show! Any chance of you putting a few pics up on the site? Beside Detroits, I love the Cummins KTA's & the Mack V8's. 3408's don't thrill...
A few thoughts on V-8 Cummins diesels. The 555 was marketed as an alternative to the 8V-71, and was supposed to offer good economy and better acceleration...

Hi, Does anyone know anything about the Cummins CT-175, CT-190, V6T-300 and V8T-375 turbocharged diesel engines? The CT-175 and CT-190 both displace 464 cubic...
Is it true that the first Cummins V-6 and V-8 diesels, the V6-200 (VIM) and V8-265 (VINE) respectively, were actually built under license by Krupp in Germany? ...
I have a 1970 Cummins V6 & V8 maintenance manual. The only V6 in it is the V6-155 (378 cubic inch), it is the V6 version of the 504 cube V8 with 4.625" x 3.75"...
