C80 Spec Tags
Here is the trim and "SPID" tags from my 1965 C80 Cab/Chassis Chevrolet. It was built in Pontiac, MI and then outfitted in Elmira, NY by American LaFrance.

Re: C80 Spec Tags
Thanks for sharing. The standard C 80 looks very similar to a heavy duty C 60, which was known as the C 60H. The narrower fenders indicate it has the 7K front axle. The wider fenders kick in at 9k. Here is some info on standard and optional equipment.

Re: C80 Spec Tags
Great looking truck.
Wondering what the GVW is. I can't tell by the numbers, but I'm sure it's a 5-Speed. Is it a Clark? Also does it have a 409? I bet it has real low miles.

Re: C80 Spec Tags
I believe the 409 is what brought it up to be a C-80. Real impressive truck. You may have seen some of my posts on the '62 GMC 6500 that I used to drive. The 6500 is basically equal to a Chevy C-80.

Re: C80 Spec Tags
IMO, a GMC 6000 with the 401 would be closer to the range of heavy duty C 80 with 409 and optional heaviest front and rear axles. However, I do think the C 80 max GVW of 25K seems way too low when equipped with a 9K front and 23K rear, should be in the 30K GVW range.

I believe his C-80 has 7 Fronts and 18,500 Rears. That's why I indicated the 409 brought it up to a C-80. Otherwise it would have been a C-60.

Re: C80 Spec Tags
Something is screwy with the way the Chevy C 80 tops out at 25K in all the literature. When a GMC is ordered with the same optional heavy axles 9k, 11k front and 22 or 23K rear, the GMC is rated in the 30-32K range. IMO, a heavy spec Chevy C 80 should be listed with the same GVW as a GMC, why it's not, is a mystery to me. Side note, a 6500 is just a higher powered 6000, ( 478 vs. 401) otherwise same available axles.

Re: C80 Spec Tags
Right, the '62 6500 I used to drive had 9 Fronts and 23 Rears, giving it a GVW of 32,000.

Also discovered another thing. Seems like most singles axle 80's, '63-'66, did have the narrow fenders with the lighter fronts. I guess all the C-80's I've been observing online through the years have been either '60-'62 or tandems with heavier fronts and wide fenders.

For some reason, Axles don't always add up to the GVW. My '67 7500 had 9 Fronts and 22 Rears, which should have had a GVW of 31,000, but the plate stated 27,500. May be a good question for Bob.

Re: C80 Spec Tags
To add more fuel to the C 80 max. 25K GVW mystery, a heavy duty 60 series, known as the C 60H comes in at 24K GVW. In my book, a C80 with 11K front and 23K rear ( maximum optional axles) is a conservatively rated 30K GVW rig. Great extra heavy duty truck to find without having to get a CDL.

Re: C80 Spec Tags
Not sure about back in those days, but these days it is common to see a class 7 truck that would normally have a 30,000#+ GVW downrated to just under 26,000#'s. It's a CDL cheat, idea is to get a more durable truck without requiring a class A license to drive. Chevy even has a downrate package currently available on the 7500 LCF. You get the higher rated axles and tires but the GVW is the same as the 6500 model. Going back to the 60's era Chevy yes sometimes the only difference between the 60H and 80 was the availability of the 409 engine as Bill pointed out.

Re: C80 Spec Tags
This is from the 1965 Chevrolet Owners Guide for Series 50-80. It mostly reinforces the above comments but it also seems that tires are a factor.

Re: C80 Spec Tags
More on the C-80. Check out this video that is indicating the new '62 Tandem Axle Dump has a 409. Having a 409 would make it a C-80, but check out the picture on the YouTube video as well as the truck at the 1:04 mark, I'm not seeing a Straight Front Axle. The '62 GMC 6500 was the first year for it in the '60 to '66 trucks and I believe the '62 C-80 followed suit.
Edit: I dug a little deeper and it looks like the Straight Front Axle was an Option for the C-80 in '62. Also note the mention of the 4-53 Detroit available in the Mediums:

Re: C80 Spec Tags
Interesting truck.
The other thing that I'm noticing C-80 Chevy vs GMC 6500. Standard front bumper on the Chevys. The GMC has a much different and heavier bumper, similar to the newer low hood 9500's.

Re: C80 Spec Tags
Right, those 6500's are brutes. Note front wheels on this one, similiar to wheels found on crackerboxes, flat hub cover, but the wheel extends outside of tire.
