I feel like you guys are Ecomodders!! I actually really enjoy the MPG content. Would like to see more mileage focus content. Maybe some aero mods and some carb tuning. There is a lot you could do to improve MPG. Hope you do more. Thanks for the content.

If you put a 3rd gen. Cummins in that truck with a smarty jr tuner. Ill bet youll get close to 18 mpg. Easy.

My buddy gets 12-13 miles per canadian gallon out of motorhome and its a POFSHAT. So, yes you are right in the ballpark. Next, you need to add a good HHO kit to it

You should look into some kind of wind deflectors to put on the back of the box. Some of the trailers I haul for my company have them and it makes a noticeable difference in fuel economy.

What the hell? Almost 9 mpg in a 40ft long brick that's probably 8 tons loaded with a carbed big block and straight 80's factory setup other than the overdrive and distributor but that's still basically 80's tech. And I get MAYBE 1 or 2 better in this damn 01 6.0 with the same 4l80e and unloaded. Other than the 10 gallons of water I have to carry til I finally put a radiator in it. Already had to do a water pump right before the cap cracked so not getting in a hurry. I don't know what GM did with these first gen vortec 6.0's but they suck on mileage.

The first time I saw the new paintjob, was at a red light about 15 miles away from AMS and the truck passed by on the way to an event. I didn't get to go to the show but it was still awesome just seeing the truck for a moment

Will this show be sold out like Roadkill? Then will we get told that episodes will be released after Motor Trend rakes its fans for money?
Asking for a friend. Because I've pulled my subscription to all things Roadkill associated.

Should do a LPG conversion- perfect application. LPG/Propane is cheaper and is 100 octane.

you also burn through it much quicker.

you know it just hit me at 10:20 while looking over this truck with the hood up, did you buy this truck as it reminded you of the white trucks they used in the first two cannonball run movies?

Run Auto-RX engine oil treatment through it (following the exact instructions), combined with Chevron Techron fuel additive and you'll hit 10 mpg.

Pretty sure that store at 13:50 was over in Dawsonville. Loving the progress on the truck brotha, been looking for it for awhile now lol y'all are so close! Lol love from Gainesville!

I can't believe a giant big block powered truck with the aero of an office building can't get better MPG than 9!!! LOL.

no wonder why why this man use a cap on the head and black tint sunglass on the eyes

You would get MUCH better mileage if you put a smaller diesel in it....

For me, an new-age European mechanic, this diagnostic part sounded like some straight up medieval shit xD ~40yrs of difference

How did he mate a 4l80 to a 454? I thought you could mate the newer engines to the older transmissions but not the newer transmissions to the older engines.

Just get a diesel engine in it you get better pull and mpg rate on long run .You just wasting money on gas. Member diesel got more tq than gas engine and use way less rpm then gas . That means less fuel using on mpg.lot more tq. Than gas engine. If was me i put a duramax disesl engine in it.

Is it not common knowledge these days on the how's and why's of ignition advance mechanisms? I mean it is great he is explaining it, but I thought this was more known to most gear heads that grew up with this stuff.

now get some more badass arrow-d  accessories, get rid of the giant mirrors and check the tire pressure.

It needs a Diesel Engine in it!
ABOlsen69X - 18 days ago
No. It needs a stroker crank and a blower on top.

EFI , roller cam with roller rockers , headers and a Gear Vendors would be a good start to better mileage. Also a set of better flowing heads. Sadly GM put "peanut port heads" on the 454 which made no sense.

another huge problem is the new gasoline has a boiling point as low as 80 degrees at our atmospheric pressure. Fuel injected doesnt have this problem because it is under pressure, but carbureted has no pressure in the bowls
