Are there any regular cab dually picture threads?

[rs74]

I have seen a couple dually threads but most are crew cabs. I am looking for just RC. Lowered, lifted, or just factory. 2wd or 4wd. I have started to look for one and I think I may have found one to start with. It is a 2wd. Already thinking about lowering one if I get one.

i got my 75 c30 2wd but i lifted it with 3" coil spacers. i wanna convert it to 4x4 if i dont sell it. only 81k original miles and no rust or dents only paid $350 from original owner

I am building this one from a C&C, it will end up with a 10.5 ft reg box when finished.

Love them! Keep them coming.

You know I use to not like duallies so much but all that has changed. They seem to grow on you. Here is on that I am looking at now.

[rs74]

And I would really like to build one like this.

an original paint 79 gmc w chevy grille ....

and an original paint 80...square lites

2 tone brown/beige was popular combo

As usual I cant let a dually thread go by without posting.

yea could we?I may be getting one .I think.

[C-10 simplex]

i'm thinking of getting one also. That's why i want to talk mpg.

[TwinTurbo]

I made a 70 km trip and uit cost me 30 liters of gas....not very economical

Well then, in all seriousness, the way the truck is setup, the load you are hauling, the way you drive makes huge differences.

As mine sits, unloaded, a K30 with a SM465 (no overdrive) 4.11 gears, and 35" tall tires, 350 v8 and original carb I get roughly 12mpg, that is all wide open country driving probably 95% highway 5% city, and babying the throttle. Recently I made a 200mi round trip 70mph on the interstate with an empty trailer there, and then a 69 K5 Blazer and a bed full of parts on the trip home, I averaged 10.5 that day. A couple weeks ago I made another trip, about 100mi round trip to pick up a 71 C10, about 75% highway 25% city, I got right at 9mpg that trip.

I have had bad tanks too, 8mpg or so when I have used it around the farm a lot.

These numbers are all hand calculated, fill the tank to full, mark down the mileage on the odo. I do apply a 15% correction factor due to my taller 35" tires vs the tiny 30" tall stock tires that the odometer was calibrated to.

Also I noticed my mileage bump up about 1mpg when I went to the 35"s due to my highway driving and keeping the rpms down on the highway. If you did a lot of city driving, I'm sure you would have the exact opposite results.

I would guess a big block truck would be 2-3mpg less unloaded, and maybe just 1mpg or so less loaded.

Would converting over to a 6.0L FI engine make that big a difference in these trucks for mpg's? Not wanting to sidetrack the thread that much but just wondering.

That is the plan for my truck after I am done with my 67 (which is also getting a 5.3). Not so much for a MPG gain, but rather the power and reliability. I had the 6.0 in my 2001 2500HD and loved it, I had 5.13 gears and 38" tires, I routinely got 12-13 mpg (with the 4l80e overdrive), and dropped to about 10mpg towing heavy. Before it was lifted, when it was on 33s with 4.10s I got 16mpg a few times, but normally stayed around 15mpg, and got about 12mpg when towing in the mountains. And that truck weighed probably 1500lbs more than my dually.

Without overdrive, I don't see the 6.0 making a huge increase in mileage, maybe 1-2 mpg, but along with an overdrive transmission you would see better results.

I won't be going overdrive with my swap, as I want to keep my sm465, but the LS engine should be happier cruising along at higher RPMs for long periods of time.
