Crazy gas mileage rambling
So the main question is realistically what is the farthest distance you can travel on one tank of gas?
End goal being to travel as far as possible in a 4x4 67-72 truck/blazer. Must use a points distributor and carb. no electronics. So what engine would we start with? 6 cyl? Diesel? SBC? How much gas can you realistically carry? At 7 pounds per gallon a custom 350gallon tank is 2450 pounds of fuel. So we start with a 3/4 ton truck just to carry it. Plus the weight of everything else you will be carrying in the truck. Which then affects gas mileage... 6cyl might be nice for mileage but going up a hill with 3000 pounds of gas and gear might not be optimum and give the opposite effect. OD auto trans? 4speed? 5 speed manual? 2.7x gears? will it leave the line with weight with those gears? throw ideas and thoughts at me. yes zombies are coming and i dont want to be anywhere near LA when they do. |

Re: Crazy gas mileage rambling
Well first thing, engine. 327 or 350 get reasonable milage. 2nd would be trans, I go four speed, 5 speed would be ideal, but not sure if we are doing swaps and conversions, or just stock. 3rd is gearing, I think 4:10s are good. Milage is ok, coupled with 4 speed, we can gear down going up hill, and with my 327 and sm420 trans, I can do 75 if needed. 4th, I am partial to 4x4, you never know when we have to leave the pavement to evade zombie infested wrecks. I get close to 10 mpg with my4x4 69 3/4 ton 327 with points and a carb, sm420 with 4:10 gearing
so about 200 miles on a stock tank. Now I have to ask this, if we go with a custom fuel tank, anything over 110 gallons has to be plackered as hazerdous and we have to have a hazmat license. But if we are running from Zombies it aint gonna matter anyway.

Re: Crazy gas mileage rambling
didnt know about the 110 gallon rule. good to know. but yea, ill be running over zombie cops too.
I did mention 4x4 thats a must. The "farm" is 2500 miles away. 10mpg, well lets say 7 since ill be carrying a full load. i need a 350 gallon tank minimum. Next issue then is the size of the tank. A 350 takes up most of the bed and almost definately wouldnt fit inside a blazer. I need to dig up my algebra. If I had a custom tank that snug fit in the bed covering the whole floor, how many inches high would it have to be to get me 350 gallons? Then my bed is still completely useable just "shorter". I suppose Ill want to have a couple cases of oil, a couple rad hoses, a ****load of duct tape. gear oil and grease. a set of plugs and points and wires. I figure I can rip whatever else I need off something along the way. |

Re: Crazy gas mileage rambling
ok by my quick math a 100 gallon tank is 4x2x2 roughly. That comes to 6.25 gallons per sqft. so if you made a tank 18inches tall by 5 foot wide by 8ft long you would get 375 gallons. thats a big tank, but that will get you were you need to go. Add side racks to the bed and weld some rails to the tank when you are building it and you can haul your oils, and the rest of your gear securly. on one of my L shaped tanks in my work truck i welded some 1 inch tube steel to the lower section making a frame to hold 2 five gallon buckets of oil. I am partial to a heavy bumper and grill gaurd, a smashed radiator puts a crimp in the journey.
Also may think about supplies for when you reach your destination, water etc.

Re: Crazy gas mileage rambling
Has SOMEbody has been watching Doomsday Preppers!?
![]() Well, if you'd like to be slightly less than obvious (i.e. hauling a 5th wheel with your own tanker trailer), you might do the following with some reasonable results: Factory cab tank - 20 gal Add factory Aux tanks - 14 gal each = 28 gal Add a rear tank under bed - 16 gal (est, depends on mfgr) So, 64 gal... @ 10 mpg - 640 miles (i.e. L.A. to Provo, UT) @ 7 mpg - 448 miles (i.e. L.A. to almost Flagstaff, AZ) @ 5 mpg - 320 miles (i.e. L.A. to Mammoth Lakes, CA) Attached is a pic of the factory saddle tanks hangin down, somewhat stealthily... I'd want an o/d trans of course - and it will have better low end usually as most have higher (numerically) 1st geat ratios along with the o/d. Be forewarned, an o/d swap into a 4x4 isn't a cakewalk, requires engine move forward in some cases. Doable though. And probably need a v8 minimum to be able to haul all your extra weight before burndown. Big block too much a guzzler. Fuel inj would help mileage, but realize you don't want electronics. Also, could consider adding a "tool box" that is actually an additional gas tank. Where ya gonna hide all the filler necks!!?? Well, hopefully that will get you far enough away from the zombie apocalypse. And good on ya, because if there is one, I'm quite certain it will start in L.A. |

Re: Crazy gas mileage rambling
Somehow this reminds me more of the Chevy van in Gumball Rally than anything else. But then MythBusters did prove you could easily outrun a burning fuel leak. Carry on gentlemen.

Re: Crazy gas mileage rambling
Like odog, I am concerned that your radiator may be compromised in the running over of zombies, although the structual integrity of their skeletons is already weakened in my understanding of zombies I would suggest some sort of bull bar, cattle guard, or grill guard and that will also add to the weight.
Then there are tires, maybe some armored vehicle tires would be up to the task. Assuming you would also be equipped with an arsenal of ammunition, what do you suggest for zombie slaying? .308 or larger? I like the 50 cal muzzle loader for dismembering but that is a little slow to reload when you are under attack by a herd of zombies.

Re: Crazy gas mileage rambling
If you build your bumper right your need for ammo would be greatly limited. Though I'd upgrade your wiper system and make sure you have plenty of extra washer fluid. Or just use a nice plow, so the red mist gets diverted away.

Re: Crazy gas mileage rambling
i would suggest swapping in an old 12 vavle cummins and a 5 or 6 speed...probably get 20 mpg with say a 3.55 gear, might do better than that

Re: Crazy gas mileage rambling
I just went from Macon GA to Houston TX on one tank in my TDi wagon...16 gallons, 828 miles.
Which has nothing to do with your subject, except that it does. Diesel is the only way to go...I would do a Isuzu or 4BT swap. They are much more fuel efficient ( 20% more, which means 20% less fuel to carry), and are more flexible in the fuel they will burn. No diesel? how about kerosine, used motor oil, gas mixed with motor oil, vegetable oil, jet fuel? plus the fuel is easier to find in large quantities. The typical broken down car has 20 gallons at most, where as the broken down 18 wheeler can have 400-500 gallons. Not mention all the military stuff is running diesel. Then we get into the much longer storage life of diesel, especially with the ethenol crap they are putting in gas now days. I will not even mention that diesel is safer to store and carry.. |

Re: Crazy gas mileage rambling
holy crap this thread took off while i was sleeping.
im actually nt a big doomsday preppers fan. I think they take the biggest kooks and make us all look like tinfoil hatters. I've actually been preparing since 1998... so the farm is stocked... Just have to get there. I thought I'd have a plane and pilots license by now but life got in the way. Preppers does give me some cool ideas though ![]() Great ideas. I dont plan on wasting any ammo on zombies. You know how much bullets cost these days? Gotta just keep trucking so a cow guard will be in the works. However if we have some fast movers I prefer akimbo style 1911s with hollow points. no need for large caliber due to the afore mentioned weak skeletal structure of a zombie. ![]() Bullets are mainly to keep all YOU grasshoppers away from my ant hoard. I spent my summer planning. Did you? bang. I'm not in a rush so the diesel swap is interesting. I can get past flagstaff with my current vehicles. Its just not very zombie proof... An emp strike would take it out and it doesnt carry all my stuff. For tires i figure I can grab wheels and tires along the way. No need wasting storage space. yea another thought on 350gallons of gas in a truck. That would be a bomb and a half if the madmax types threw a flare at me. |

Re: Crazy gas mileage rambling
The biggest mistake you always see in zombie movies with drivers is the drivers drive way too fast and then wreck. Take it nice and slow and your radiator should be safe with a regular guard.

Re: Crazy gas mileage rambling
I agree with the calm driving, it conserves fuel as well. The diesel idea is something to think about, especially if you have the time. You would have good power and torque, low risk of the 350 gallon tank exploding, fuel is easier to come by on the road. I agree with the thought of no electronics, an emp would be the end of the line. This is an interesting thread, I am glad to see that I am not the only one who thinks of these things, you never know how things are going to turn out, or what is going to happen.

Re: Crazy gas mileage rambling
I say go diesel engine and make your own bio-diesel. The only problem is the zombies might smell the exhaust and think it's french fries.

Re: Crazy gas mileage rambling
I understand the questions, but haven't seen the "Why" for doing this. Is it some form of competition, which is the only thing I can read into seeing how far you can go on a tank of fuel. That brings some other factors into play that would theoretically alter the outcome.
As far as the question goes, it seems that NASCAR and other racers have been trying to answer that as long as they've been racing. The sanctioning organizations have continued to level the playing field, as best they can. So, what is "fueling" this quest?

Re: Crazy gas mileage rambling
zombies. the starving masses. earthquake. emp strike. fukashima ( I live beside san onofre)
Its sort of humorous, but not really when you think that gas trucks deliver gas daily. grocery stores are stocked daily and dont last the weekend of memorial day much less a hurricane. can you image LA/OC with the biggest concentrated population of **** bags, rapists, theifs and general scummery in the civilized world, all hungry, sick, hurt? yea im planning on getting the f out of dodge. I dont stay awake nights thinking about it but it would be idiotic to buy another iphone when you dont have at least 3 monthes food in your house. imnsho. |
