my 86 with a 6.2 got 26 all the time with 31's (that is what it came with from gm) and now with 32 bfg's (much heavier tire) it gets 21-22. Also has military pump and injectors.

Well what do you think would be more economical? Homemade Bio or Homemade E-85?
I know with Bio the rate of consumption is roughly about the same. With E-85 it's alot more, so at a manufacturing standpoint, I wonder which would be more economical. Also trying to look at that from a SHTF perspective.

i loved my 1 bbl 292's. drove em for 10 years...in the back of my mind i have an urge to build a "new" one...injected of course. you need to do some head work on the newer ones, but they can be great motors......stock they were about 120 hp @ 3600 rpm......i think around 220 ft pounds @ 1800 rpm.
somewhere i saw a site that makes an injection setup for these. did GM make a TBI version of these motors?

Can you even make homemade E85?
Biodiesel has less energy in it than dino-goo diesel. You will see a loss in power and economy similar to E85's loss.
Not saying home brewed biodiesel is a bad idea or not to do it...just that it isn't as simple as "getting biodiesel" and "pouring it in the tank and driving off happy". Needs a lot of prep work to make sure your vehicle keeps running and just to have the equipment to make the stuff.
I was all over it a few years ago but now, not so much just due to my particular situation.

Well you can make up to 85% of it, the other 15% is still at the pump
backward dude e 85 is 15% alcohol and 85 percent gasoline

I'm considering to buy a late 70's 4x4 Suburban with 350 gasser and 350 trans. I'd like to convert it to a 5.3 Vortec, that's controlled with Megasquirt.
Could that 21 mpg be possible on a old truck with modern engine?
MAYBE freeway with stock sized tires, no lift, OD trans, and freeway gears. Definitely not in a wheeler.
Quite a few of my friends get mid to upper teens with around town and 55mph driving out of their 5.3L Silverados. They can touch the low 20's with conservative driving on the freeway.

Sounds good. Suburban would be built for daily driving, little city and mostly highway @ 50mph. For wheeling I have a K5.
It would still be quite pricey to drive with gasoline, so it will be converted to CNG. It would be cheaper to drive than my stock CTD Dodge Ram, and with two 26 gallon CNG tanks I get quite a good range from it, fill up once a week with my miles.
Just a thought but I noticed the OP mentioned 36 in tires on a 16.5 rim so he may be referring to military take offs.don't know about everyone else exsperience but I have the same tires on a 9.75 rim and they measure 34.5. So I would vote 4.10s for gears.

Give me to payday on Friday and I can tell you what a stock 91 on stock tires will give you. So far it's looking pretty good.
my 2001 2wd silverado with 5.3 got crap in the city like 13, and maybe 19 highway. My van with a 350 can get about 18 highway, and 15 city. Idk gears in either, i intend to check on the van, but the tires are only like 28" tall so im sure that helps and im sure its more like 3.42 gears, or lower possibly. (higher, idk whatever you feel like lookin at.)
83 k5, 305/700r/np208/10 bolts with what i think is 3.08 gears, 33x12.50 bfg km2's
was getting 15 city, 19 highway. did not use overdrive as it wanted to constantly shift in and out of it.

Lol ok then higher gears, thx man lol. Odd thing is, and why i need to check the gears on the van, i can get 18 highway and still get 16 city, and if the gears are really high, i would think it would kill mileage in the city, but 28" tires prolly do wonders for that lol.
