Re: yet another MPG thread
 

350 built a little with long tubes, TH350, 3.42's out back on 235/75's 10-13mpg

Re: yet another MPG thread
 

340 hp 350, 5.13 gears, SM465, 32" tires, 5200 pound 3/4-ton 4x4 = 7 mpg city, 9 mpg highway.

Nothing like 4000 rpm on the freeway to suck down the fuel.

Re: yet another MPG thread
 

amen... i love to drive my truck and at one time it got good milage! when it was stock!!! for real when my 77 big ten was just single exhaust and all that i had no urge to kick in the 4bbl and i could go a month on 40 bucks of gas. i bet if i kept it at 55 back then i was geting 14 or so to the gallon. but when skool started back i wanted a good sounding truck. so i asked mom if i could get duel exhaust for my truck to "help my milage" (dont we all tell this to our parents just to get more power?) well i dumped like $350 between duel exhaust through summit turbo mufflers, k&n air filter, and a flex fan. it probly helped a little but not much, it did more hurt than help i think couse every where i go now i make them pipes do some talking and i probly get like 8 or less becouse of jack rabbit starts and all that. but if i changed my driving habits id be getting "good milage"... for these trucks

but if my 350 ever blows i want to drop in a 250 stright six and a t5 and make it a nice high way cruzer

Re: yet another MPG thread
 

18-19 in town, 20-21 on the highway. 5.3, 4L60E, 3.42.

Once I have a new truck bought, then the 5.3 will get built up, or replaced with a 6.0 and built up. By then, I won't get two poops what it gets for mileage.

This crap needs to stop, NOW, or you just might get a free vacation.

Re: yet another MPG thread
 

4.3L V6, MY6 OD trans, 3.73 rear axle, P235/75R15 tires = around 20 mpg.

Re: yet another MPG thread
 

Umm , I have a one ton....All you need to know is,It has 2 20 gallon tanks........Nuff said.

Re: yet another MPG thread
 

I get 8 mpg's out of my 402. It costs me $18.00 each time I drive it to work & back. Just did it today for the second time this month. In no way could I afford to do it all of the time. I sure enjoy it when I can. It's worth every penny.

Re: yet another MPG thread
 

last i checked was around 10ish, 85 4x4 lwb 355, aftermarket cast heads, mild cam, 700r4, 4inch lift and 33's

Re: yet another MPG thread
 

Any thoughts on an 87 lwb 305 tbi, th400 and stock gears... all i know its a ten bolt. Any idea what i would get? I know this question gets asked alot but i kinda think it would be cool to know... not that it really matters, its a toy anyhow. :)
thanks
Chris.

Re: yet another MPG thread
 

im gettin around 9 miles a gallon with a 355 w/ double pumer hooked up to a TH400 and 3.07 gears in my 1970 C10 daily driver.

Re: yet another MPG thread
 

Yo!
About 12 with FRANKENTRUCK's build,...but they're all "smiles per gallon", as well!! Not much else like it.

Re: yet another MPG thread
 

Mine gets about 7 MPG with a TH400 and a 350 engine, 4.1 gear ratio and a rochester quadrajet.

When I read the numbers in this topic, I get the feeling that mine needs a tune up.

We driver about 50/50 highway and city. On the highway doing about 55 MPH and in the city we are allowed to drive 30 MPH here in the Netherlands.

It runs on LPG (Liquefied Petroleum Gas) wich costs € 0,57 per liter here in the Netherlands compared to € 1,54 per liter for regular gas.

any ideas on how to improve my mileage?

6.2 700R4 3,08 23-26MPG diesel
99 2500 Xcab 2wd 5.3 4l60E 3.43 15mph at 5600 lbs

Re: yet another MPG thread
 

Re: yet another MPG thread
 

I have no idea what I'm getting but now I'm interested and will have to figure it up on my next fueling cycle

Re: yet another MPG thread
 

The burb in my sig. 23MPG Highway, I still have to build a cold air intake and water/mist injection. So I should be at around 25mpg when done.

Re: yet another MPG thread
 

wow. makes me want a 6.2 diesel :lol:

Re: yet another MPG thread
 

So get one! I count the 0-60 on flat ground at about 10 seconds. Not bad for #6000. Its nice and fast and pulls anything with great mileage.

Re: yet another MPG thread
 

I got as much as 14 from my stock 350/350 3.08 geared 69 lwb. But I drive it like an old man.

Re: yet another MPG thread
 

I will, soon lol just need to save up a little

Re: yet another MPG thread
 

I get about 10ish

Re: yet another MPG thread
 

'85 K30 Crew Cab Dually, 454, TH400, 3.73 with 34's and I get 8 mpg driving to work and back which is 14 miles with a 1000 ft elevation gain and many hills. I haven't driven it on the highway since I bought it and got it tuned up for the elevation (it was WAY too rich and didn't have nearly enought advance for 8,600 ft where I live.

'84 M1009 CUCV Blazer 6.2/TH400/3.08

I've checked mileage twice so far, and I got 20.2 the first time and 21.4 the second. This is mixed driving, but more in town than highway. I gotta think 22 - 23 is totally possible on the highway. I have a Banks Sidewinder turbo kit that I'm going to install soon. I've heard some people say the Banks kit slightly decreased their mileage and I've heard others say it got slightly better. For the proven 100+ lb ft gain in torque, I'd be OK with a little loss.

Re: yet another MPG thread
 

My 84 GMC lwb (350, 700r4,3.08, 255/75/r15) got 14 last tankfull, with me driving it somewhat aggressively. if im on the highway i go 70-80 mph, i was expecting less, so im happy.

My 70 chevy lwb (350 with 600 double pumper,th350,3.73) gets roughly 8-10, with me driving it like i stole it, I have ALOT of fun, so im happy.

On the other hand, my 2000 chevy swb (4.3,4l60,3.73 4x4) gets 10. best ive ever gotten was 12. for a fuel injected truck? FAIL. screw V6s. ill take my SBC over the v6 anyday!

Re: yet another MPG thread
 

Just throwing it out there, recken your carb is not calibrated to run LPG?

Re: yet another MPG thread
 

Thanks for your reply.

I would not know. My car also runs on regular fuel, just for backup, but it should be set for LPG now, because that is the main fuel. I will give the company that fitted the system a call and ask them what they did exactly.

Re: yet another MPG thread
 

im assuming mine is about -12 lmao

325hp 355 sbc turbo 350 stock gearing 3/4 4x4 with air conditioning lifted 4" on 35" mudders.its horrible..:( and its a daily driver.

Re: yet another MPG thread
 

that actually normal mine gets half that and mines daily-ed. but thats why I'm going with a 6.0 and 4l80 I'm hopping for 12 to 14 in town

Re: yet another MPG thread
 

My 4barrel 305 with th350 3.73 gears, I think gets feet per gallon.

Re: yet another MPG thread
 

I get about 8-12 depending on what I'm doing. 350 bored 40 over with 4 barrel Edelbrock and dual exhaust with cherry bombs, full time four wheel drive and TH-350. The Full time 4x4 kills it. The worse I've ever got was 5 or so.. Getting firewood.

Re: yet another MPG thread
 

385 stroker engine, with 700 R4 and 3:73 gears and 28" tall tires====15 MPG Highway---a lot less on the city street cruisin (Wink wink)

Re: yet another MPG thread
 

My old C30 with 4:10 gears got 7-8 with my foot in it all the time. I once got 12 out of it for no reason, redid my math over and over and never could figure out why it went up.
