I scaled my 53 3100. This truck is stock with the exception of a 12 bolt rear end and open driveline. No driver, no water in the radiator. I found it interesting how well balanced it is. I thought the rear would be lighter. I leveled the truck and aired the tires. These are quality race scales. This truck is like sports car balanced. 1. Total weight 2. front, rear 3. Left, right 4. Rear left, right front. 5. Right rear, left front.
I had my truck weighed twice while leaving a landfill on scales that are not near as accurate as race scales but both times the total weight including me (roughly 200 lbs) and a set of tools behind the seat came to roughly 3400 pounds.
When people say "That heavy old truck would plow through a new car." I like to point out that most S10 pickups outweigh this "heavy old truck".
The balanced front to rear ratio explains why my truck gets around so well in snow with a decent set of tires.
An LS engine, weighing in at an easy 150 pounds less than the original 216 would almost make the truck rear heavy.
My 3/4 ton GMC says 2785lbs. Lt weight. Its painted on so it must be accurate right? Hahahahaha. I have a feeling its more in the 3400lb bracket as it sits with the LS. Now im curious. Next time I have to work at one of our plants I will get it on the scale.
About 30 years ago my 52 3100 with some gas, me, a sheet of plywood in the bed and nothing else (no spare at that time) weighed just over 3200 on the scales at a rock yard. If you've never hauled rocks in yours, they weigh you in empty, load the rocks you want and weigh you loaded (to make certain how much to charge you and so that you don't leave over-loaded).
