The links show pictures. So, is the Cummins original? A 225 HP V8?

Re: 67-72 C/K/T-40's-90's!
 

Tim, I questioned it too, but it is listed on the SPID.

Pretty rare, but I do believe I've seen them listed in the Brochures.

Re: 67-72 C/K/T-40's-90's!
 

I took the pictures, then talked to the owner for a while afterwards ......we may have discussed sales . He mentioned he only bought it because "it is placarded at #10,000 so it is registered just like a pickup" ....I did not go back to check and am sceptical... . It is possible it is under 25 k as I think the 10k number is actually towed weight...and the 25k is tractor... ...

Re: 67-72 C/K/T-40's-90's!
 

It looks over 26,000 to me.

If he registered it that way, it doesn't sound right to me, unless Alaska is different on it.

Check out the GVW tag the next time you are there.

Re: 67-72 C/K/T-40's-90's!
 

Not listed directly on the SPID, but the rear axle number looks to me to be a 18k? Is that how the model # works?

Re: 67-72 C/K/T-40's-90's!
 

Not sure, but even if it was a low of 18, it looks like the Fronts are 9, which would give it a 27. My 7500 had 9 Fronts and 22 Rears. My best guess would be pretty close to the same, especially being a Road Tractor. But as mentioned the GVW tag would tell us for sure, if you ever have a chance to get back to it.

Re: 67-72 C/K/T-40's-90's!
 

I think I have, too. I saw the SPID. I didn't realize, or forgot because I never see them, that Cummins did a 225hp V8 back then. I think I did know there was a Cummins option, just assumed it was an I-6.

Re: 67-72 C/K/T-40's-90's!
 

I thought we had seen examples before. (at least in the C-60 series) of intentional "under rating "

Re: 67-72 C/K/T-40's-90's!
 

Many of the newer Mediums (approx early 90's and newer) were made to be as heavy as they could but yet under CDL, but before then many would go over. I don't ever remember a 7500 under CDL (26,000 or lighter).

Re: 67-72 C/K/T-40's-90's!
 

We just bought a bunch of Freightliner M2-112's. The trucks are spec'ed out basically the same as a 33,000# GVW model, but have smaller tires to limit them to 26,000#'s. That way anyone can drive them, but they are more durable than a regular 26,000# truck.

Back to the truck in question, the V-series Cummins were in GM trucks for a number of years, though not too common. Probably most often seen in Fords, but I saw a few in Dodge heavies. Funny thing about those Cummins V-8's (there was a V-6 version too) was that Cummins tried to sue GM over the Toro-Flow because of them:

Re: 67-72 C/K/T-40's-90's!
 

My single axle flatbed bed is also a 7500 (chevy 70) with a weight tag under 26000.....it came without a glove box door, so no SPID....

Re: 67-72 C/K/T-40's-90's!
 

What does the GVW Tag actually say? Along with the Front and Rear Axle Weights.

Re: 67-72 C/K/T-40's-90's!
 

Re: 67-72 C/K/T-40's-90's!
 

An older H-70 with a GVW of only 25,500?

But there's the proof.

Good thing I didn't bet on it, lol.

Re: 67-72 C/K/T-40's-90's!
 

So I now own the fire truck above on page 6. I purchased it locally here in SC back in March. It had been converted to a flatbed before I got it. Wasn't the best conversion as the fire truck pump is still mounted under the bed. Since purchasing, I completely rewired it with AAW Classic Update kit, new steering wheel and new carb. Runs great and everything electrical works as supposed to. I finished decommissioning the fire truck remnants as much of it wasn't operating correctly. Truck only has a couple rust holes in the cab floor and drivers rear corner where the master cylinder leaked. I'm going through the brakes now. Truck only has 25k miles and is really in fantastic shape. I was excited to find a photo of it when it was in operation as a fire truck. Looking for original side steps and hangers. It currently has custom made ones for the fire apparatus. Kinda cool

Re: 67-72 C/K/T-40's-90's!
 

Cool truck! Like the Dayton wheels too... What does it have for an engine/trans?

Re: 67-72 C/K/T-40's-90's!
 

It has the 366 with 4 speed and split rear. Engine was pretty much all original except for the dual battery addition and some coolant lines for the fire apparatus. I removed them to get it back to stock status. Even had functional cold air intake. Holley carb was spitting and sputtering; even after rebuild. I pulled it and installed Edelbrock 1405 and it smoothed right out. Well worth the $300. Trans and rear seem good - I'm not sure the splitter is operating correctly though. The wires were boogered up so I'm going to run new wires to it. Switch was replaced in 2010 as the tag showed - so I'm thinking it is the wires.
I thought it was pretty cool to find an original photo here on this site. I wondered what it looked like as a fire truck.

Re: 67-72 C/K/T-40's-90's!
 

Welcome tto the site and how cool is that for you to be showing up with this fine trucks as yours. Looks like you got yourself quite a nice truck there. I bet you're right about the wiring for the 2spd. If not that, maybe moisture got to it and a disassembly, clean, lube would do it.

Re: 67-72 C/K/T-40's-90's!
 

I've been out on the road delivering for my company recently & have spotted this truck twice. There is no for sale sign on it, but if one shows up, I will be checking on it. I know it's a '60-'66, but it is a looker.

Re: 67-72 C/K/T-40's-90's!
 

Nice truck.

Sheet Metal looks great.

It's a '66 by the way.

Re: 67-72 C/K/T-40's-90's!
 

Real nice truck.

Tried finding some original pictures of it online, but my "detective" work could not produce any.

Re: 67-72 C/K/T-40's-90's!
 

Glad to see these old heavies have a following. I hate to see instrumental vehicles like these get ignored.

Re: 67-72 C/K/T-40's-90's!
 

6.0 ls Clark 5 speed gear vendors o-d, with the exception of the kw mirrors I love it.

Re: 67-72 C/K/T-40's-90's!
 

That's interesting w/6.0 (but not mirrors). I spy a 69-72 in the background. Blazer? No top, airport?

Re: 67-72 C/K/T-40's-90's!
 

I thinks it's a suburban.
