Truck Weight
 

I found a paper in my truck from a few years ago when I went to a car show and wieghted the truck on a Highway Scale. With me, my wife and couple of suitcases in the truck box it weighted 2882 pounds on the front tires and 1914 pounds on the rear tires for a total of 4796 pounds. I didnt realize out trucks were that heavy and that is one of the reasons it is hard to get good gas mileage from our trucks, especially with original drivetrains in them.

Interesting.....is your truck a 1/2 ton or 3/4 ton?
Its a little deceiving for sure and what makes it tough to call is almost every truck is a different weight on a truck by truck basis. The base weight they list in the GM brochures etc (something in the 3600lb range? or?) is for a base model 1/2 ton with a base model engine (6cyl) with no options. Of course the weight starts to climp up from there w/ a V-8, ps/pb, deluxe trim...and a/c and an 8' bed, etc you are quickly tickling 4000lbs+
I've had a few 1/2 long beds w/ 350's and a good option group.
What I've found is the trucks w/ me in them tend to range from 4100lbs to 4400lbs empty.
I've even tried this weight check by making sure the spare tire isn't in the truck (LOL) and keeping track of how much gas is in them. They've never been under 4000lbs....and that is a pretty heavy vehicle to start with relatively speaking.
Another thing I found was that the 1/2 ton that I had with the leaf springs vs. the trailing arms was a little less weight....which makes sense. It also made the true payload capacity of the leaf spring truck higher by a combination of less truck weight and more ability to carry weight.
My two bits.

A 1970 Hemi GTX is right at 4000lbs too. 4000lbs. is way lighter than todays trucks. Remember that a new Mustang is around 3800, so its all relative.

Re: Truck Weight
 

the weight of a 72 long bed k10 i had a few years ago was at 4100 empty

Re: Truck Weight
 

My truck is a long wheelbase C10 with a big block and Turbo 400 trans and being a Chevy had trailing arms. Of the 4796 Lbs me, mom and the suitcase was probably 450 of it which would bring it down to about 4350 dry weight.

Re: Truck Weight
 

4000 lbs isn't to bad really. A dodge 3500 diesel mega cab weighs in over 8100 lbs.

Re: Truck Weight
 

Yeah, thats sound right in there with the info I got out out of the weigh stations, etc. Is yours an a/c truck?
Its funny how another 'option' in these trucks immediately adds 30lbs, 50lbs 100lbs....even a unsuspecting 'overload' spring option adds another 75lbs or a new set of oversize tires/rims.
I had a small 8' O.head camper that we used to have and we put the whole unit over the scales once when we were heading out on our holidays. I think the whole unit (1/2ton, us, camper, bikes, propane, supplies,etc) came in at around 6100lbs...which was about 700lbs more than the original GVW rating....oh well, no problems...those old GVW plates need updating anyways (LOL).
By comparison and like Syndromes info shows I took my '05 Silverado Diesel over the scales completely dry (2500HD Ext Cab/shortbox 4x4) over the scales....and it was 6800lbs...dry....LOL. Basically 700lbs more than my 1/2 ton and a complete camper/RV setup.
New vehicles are full of weight...leather, harnesses, gizmos everywhere, insulation,....more than they sometimes look like they weigh.

Re: Truck Weight
 

My 72 blazer without the top on was around 4100 lbs. 4350 with top and now around 4600 with 3/4 ton axles. For reference my 67 impala fastback was 5200. So it ain't too bad. Newer truck are heavier but use lighter guage steel. Funny how much the interior pieces and all that add up.

Re: Truck Weight
 

The GM historical Center lists Shipping weights for the 67's (fully assembled, no fluids) as follows:

115 inch wheelbase C-10
1/2 ton Stepside 3255#
1/2 ton Fleetside 3355#

127 inch wheelbase C-10
1/2 ton Stepside 3345#
1/2 ton Fleetside 3440#

No shortbed 3/4 ton C-20's built
127 inch wheelbase C-20
13/4 ton Stepside 3753#
13/4 ton Fleetside 3848#


Shipping weights moved up by about 100# by 1972 but there weren't any C or K trucks approaching those weights.

Guess the guy who weighed your truck had his thumb on the scale or you were out by the Unicorn corral where they parked all of those 454 powered trucks with the 700R4 transmissions..

Re: Truck Weight
 

Have you ever put your truck on a scale ?

Re: Truck Weight
 

I have a 71 C20 Longhorn and I weighed it the other week and it came in at 4900 lbs. I have a 65 gallon tank that was full and I have a 350/4L80E and a Dana 60 Axle.

My 2003 Duramax CCSB 2WD came in at 7100 lbs with my toolbox and some other gear in it.

Re: Truck Weight
 

Yes. 3580# without me, a 572 big block and a half tank of gas.

Re: Truck Weight
 

I am going to go back to a Highway Scale and weigh her again. I post the results in this thread. I wonder if weighing ( like I did ) the front and rear axles seperately skewered the actual weight.

Re: Truck Weight
 

My '68 swb step side with a 5.3L/4L60E weighed 4150 with me in it. I go 250lbs so that puts the truck at 3900lbs.

Re: Truck Weight
 

My 71 4x4 weighs in at around 4900.

Re: Truck Weight
 

My old '69 C-10 weighed 3740# without me in it. It was a SWB fleet, 350 with aluminum intake, TH350 trans, manual drums, P/S, no A/C.

Re: Truck Weight
 

Those shipping weights are based on 6 cyl, 3 spd, very low optioned trucks dry with no fluids. V8's, auto trans, and all other options add weight.

A big block fully dressed with pulleys, iron intake, manifolds, brackets, and the A/C set-up that most of them have weighs about 300# more than a stock250 6 cyl. A TH400 weighs around 20# more than a TH350 (wet) and a TH350 weighs about 20# more than PG.

Re: Truck Weight
 

Me in it, full tank of gas, tool kit under the seat, it comes in at 4320. I'm 400 of it, so the truck is right at 3900. I had expected it to be heavier.

Thats on the truck scale at work, which weighs in 20 lb increments and gets calibrated once a month.

Re: Truck Weight
 

That is correct and, none of those differences can make a C-10 weigh 4796 LBS as the original poster claimed. Your C-30 won't even be close to that number.

Re: Truck Weight
 

Sounds about right. My '72 K20 weighed 5300# with me in it (about 140), a wraparound diamond-plate rear bumper, and no clue how much gas but it'll hold 50 gallons. This was many years ago on certified scales.

Re: Truck Weight
 

I weighed my truck today at the scrap yard, 68 short step, 5.3/4l60e swap, no bed floor, full tank of gas and me in it (205) weighed 3780.

Re: Truck Weight
 

I just weighed my 72 C20 2wd last week. With both fuel tanks full and with me in it, it weighed 5120. It has a 350 and auto trans.

Re: Truck Weight
 

Not really.
The average weight of the sampling of trucks that the members have listed here so far is just over 4300lbs.
You need to read the fine print about what those listed weights comprises a little closer (refer to 67_C30's post).

Re: Truck Weight
 

My 1972 GMC C1500 Super Custom with 350/350, me in it, tools under the seat, 1/4 tank of gas, leaf spring rear and no spare tire, came to 4,380 pounds.

Re: Truck Weight
 

I have some scrap I could bring in this weekend... maybe I should roll the old girl across the scales...

Re: Truck Weight
 

Actually I was surprised when I had my truck weighed for "tear weight" at a rock and gravel pit. What surprised me is when I had that information I looked up what my friend's (then) modern 1994 pick-up weighed in at. I was over 1500 pounds LIGHTER than his rig.

What gives them better mileage is computer controlled engine management systems that continually changes the fuel mixture based on what the computer is reading from various sensors. Also what helps is overdrive transmissions. I would wager to say that if you put a modern V8 and most importantly all its computer controls into a 1972, put a computer controlled auto or better yet a manual with overdrive, you would get VERY close to a modern truck's gas mileage.

Re: Truck Weight
 

I used my truck for hauling stuff to the dump. Empty it always scales out at 3940 for my 1970 C20 long bed. My hummer scaled out at 7920, so I feel good about the 3940 :D

Re: Truck Weight
 

Old thread....On the scrap yard scale today 3710 lbs empty. 68 K10 4 speed 250 6 short step side. No front or rear bumper or spare tire or tail gate...GM listed curb weight is 3737

Re: Truck Weight
 

Another interesting point is that the trailing arm trucks should weigh slightly more than the leaf spring trucks due to the extra components/gear under the back end vs. the 2 sets of leafs.
My C10/Lwb/350-auto/a-c/ps-pb/trailing arm truck comes in very close to 4000...somedays a bit more.

Re: Truck Weight
 

The book numbers for a 72 C10 lwb V8 show the leaf option to be 17 pounds lighter. For those who must know its, -11 lb front axle and -6 lb rear axle curb weights.

Re: Truck Weight
 

That's interesting Tim...I always knew that the leaf spring trucks were lighter but didn't know the number difference.
I would have thought it to be a little more given the apparent differences at a glance in the 2 systems...but ya' never know.
All Good

Re: Truck Weight
 

First time across the scales (without a trailer)it was only 4780 lbs. I was surprised to be less than 5000.
67 Burban with 350/350 with a GV overdrive. Me at 195, a 3/4 tank of gas, no back seats, trailng arm rear with bags. Static drop in the front.

Re: Truck Weight
 

According to the drive on scales at the County Landfill, 70 LWB (wooden Bed) C-10 weighs 3950, with me and a 1/2 tank of fuel in it

Re: Truck Weight
 

I haven't taken my truck over a scale yet, so I can't add anything to that, but just want to say to HO455, nice bridge pic! I've been over that many times. I occasionally explore the abandoned parts of old Highway 30 north of there.

Re: Truck Weight
 

I used my '72 2wd Blazer for work for 25 years. My buddy and I weighted it, 3400 in the rear and 1800 in the front + 5200lbs (no beams). Onboard 220v compressor cords nails roof rack to many tools.

Which rear end did it have in it?

Re: Truck Weight
 

For what it's worth a dump scale says my C20 with BBC & 400TH weighed approx. 4800-4900. I don't remember the exact number, I believe high 4700-4800. Less 340 lbs. in occupants brings it about 4500 dry. Strikes me as low, then again I never fill up the tank, can only guess how how much gas is in there;), and surely it's lost some body weight in favor of self-ventilation & drip.
