    Maybe you guys discussed this before...

    I recently weighed my rig on a certified truck scale, and I was a bit surprised to find it was FAR heavier than the specified curb weight 3,677 lbs. In fact, I'd have exceeded the GVWR of 5,000 lbs if I wasn't outside the truck.

    My '71 was unloaded (except for a 20lb tool box and a spare tire) and topless. I have the 350 with the sm465/205. I also sport alum rims and 31x10.50 tires. ...Weighed in at 4920lbs. It does make sense for the rig's size. I just hope a cop doesn't stop and cite me one day for tavelling 1,000lbs above the GVWR.

    Just for kicks, I weighed just myself on the massive scale, and it pegged me at 180lbs! It was accurate.

    3677 was probably the weight of the stripped down 2 wd version of the same truck.

    For comparison my 81 Jimmy weighed 5700lbs...soft top, 14 bolt, 465/205, and 36" TSL's.

    Even if the curb weight of 3,677lbs came from a stripped 2wd Blazer, it's curious that the K5's max-rated capacity of 5,000lbs is exceeded with no more than the driver on board (let alone the heavy fiberglass top). It just doesn't make sense. Hmm... GM must have done some funny number fudging meet 1/2-ton DOT reg's.

    however is interesting though because in the 73-up era they produced the Big10 1/2 ton trucks with a hair over 6,000 GVW so they wouldnt have to put emissions on them, they also put larger brakes on them.,

    normally a half ton weights 3500 to 4200 with GVW of 5000 to 5500, which would leave you with `roughly' 1/2 of a ton to play with,,,

    something is odd,,,,

    The only thing odd is the posted weight....does anyone honestly believe that a full-size truck could weigh ONLY 3600 pounds? There are some sportscars that weigh close to that amount!!!

    For what it's worth, I had my K5 weighed at a local race shop on a very accurate set of 4-corner scales and it came out at around 4950 Lbs. (Hartop, 35's, 1/2Tank of fuel)

    I posted the actual weights for each corner on the 1st Gen board, but I am too lazy to go find them now..... /forums/images/icons/crazy.gif

    Yeah, 3677lbs is way too light for a K5, especially when a Jeep Wrangler comes in stock at 4200...

    I have to add that my Blazer was weighed when it still sported a damn heavy 70's-era brush guard, a rather large Class III receiver, and a roll bar (I've since removed the brush guard). I imagine they contributed at least 200+ lbs to the grand total.
