My 454 Burb seems to suffer from inadequate respiration since it has plenty of low end power but seems to peter out above 3000 rpm. That would indicate headers, carb, and cam.

Sick rig man, i love the old GM's.

Nice lookin C30 you got there. My buddy used to have a C10 that we got pretty damn stuck in the middle of the woods once, and I love cruising in my other friends K5. Nothing like an old, solid full sized gm.

Oh and... 56,000 miles!!!!! Hot damn!!

Yeah I just got back form Montreal and was excited to work on it a bit but it snowed today. Hopefully Saturday will work out and I can get a fuel tank mounted. (the support assemblies are a ***** to find and dealers want to get rich off of them) Then I can move it around easier, rebuild the calipers, throw a new timing set in it and drive the pig.

16 gallon.... that's kinda small.... seems like the stockers were 20. maybe I am wrong on the newer trucks, but the 70s vintage trucks of the same general body style had 20 gallon stock saddle tanks.

nice looking truck though

I would strongly suggest a 19.5 wheel n tire conversion:
Rickson Wheel Manufacturing

the beauty of GM is you an get 19.5 dually wheels locally rather cheap like and some tread wright 225/70R19.5's would swap right under that truck and not need any modifying mount'em and bolt them on . . .

according to the advertised size the 225R19.5 is 1/2" taller then a 235/85R16 but when put next to each other they are exactly the same tire, only the 19.5 has half the side wall and twice the load carrying ability there for meaning longer tread wear under the same load.

Snoop through the rickson site and soak up the info, plus i'll be willing to answer and any 19.5 questions you have.

great tires I run the Mud treaded 19.5's on my truck's and i get 60-75K miles from a set of them an AT or highway tire will last a good bit longer. . .

Yeah, 20 gallon tanks are factory but I got the 16 gallon tanks for less than 33 bucks a piece. I can manage 8 gallons less per fill-up haha. I have been looking for some wheels and tires, but I want to eventually swap to 22.5 or 24.5 Alcoa 10-lugs.

That's gonna really pay off for you. If your rig gets as good gas mileage as my 454 Burb (5mpg with towed load) think how often you will be able to save that 8 gallons. Why, the saving could be astronomical

there ain't much to be gained by the 22.5's n 24.5's the 19.5's have the same load ranges F G and H, with shorter side wall's unless your looking for 38"-46" tall tires ? . . .

225/70R19.5 = 32.5"

245/70R19.5 = 33.3"

265/70R19.5 = 34.5"

255/70R22.5 = 37.2"

275/80R22.5 = 39.8"

295/75R22.5 = 41"

295/80R22.5 = 41.1"

11R22.5 = 42.3"

385/65R22.5 = 34.0"

315/80R22.5 = 43.1"

12R22.5 = 43.7"

425/65R22.5 = 44.9"

445/65r22.5 = 46.2"

11R24.5 = 44.3"

12R24.5 = 45.7"

as you can see they get rather tall, and the 445's are 17.5" wide . . .

Is the truck 4WD ?

The 20 gallon tanks were $150 each, the 16 gallon tanks were $32.70..... I'll suffer with the capacity loss.

As for the wheels and tires, I'm not looking for any major gains as far as load range and/or tread life. I will probably only use this truck once a week (if that) and when I change the wheels and tires, I want the 22.5 or 24.5 10 lugs just because they look sweet on a bagged truck. Changes like wheels and tires are down the road. I may just fix this truck up and sell it, because I want a diesel. This was just a cool looking clean truck that I decided to buy in the meantime.

Its cool, just figured I would offer some new info.

As far as a diesel goes I stay away from GM diesel...

I learned this the hard way.

Its all good. I welcome all suggestions, and questions.

The truck is a C3500, so its a 2wd. I wanted a 2wd because I would like to drop it on air bags. If it was a 4wd it would stay tall. I just like the way slammed duallies look with full size tractor trailer wheels.

Just put 2 5 gallon jerry cans in the back.

Problem solved. In an emergency situation...That'll get you a whole 50 miles! haha.

Exactly, haha. I'm not too worried about the milage, I would prefer a diesel but this is a clean solid truck for the age and price. Hell, Our brand new F-550 brush truck averages a whopping 6.5 MPG and its an '09. This truck can't be too far off from that.

I finally got a fuel tank in the truck yetserday with some help from my friend Andrew (mgtsldr, on this forum). The "factory" brackets I got were the right ones...... Except one was too short (I guess there are 2 different sizes) No big deal though. I drilled a couple holes, we froze our asses off, ran to the parts store a couple times and after some persuasion it was under the truck. All in all I'm happy. Now I just need to do it again on the other side (thats not high on the priority list though) New front calipers, timing, exhaust, and fixing wiring gremlins (corrosion from sitting) are next on the list. The bottom line is that the more I work on this truck the more excited I get. This thing is going to be mean!

Here I was fighting with one bracket where the strap was too short (that should have been the first hint that the bracket was the wrong size).

So to fix that I grabbed some stainless scrap and a couple bolts, made some bends and drilled some holes. I think it's time to clean the shop area a bit!



I will get some pics of the tank IN the truck today. I was too cold and it was dark when I was done part running and drilling holes.
