When are you going to officially name this truck "Mint Condition"? That name should be painted on that truck somewhere.

I asked Newbern about a potential diesel swap for this truck and he said they were toying with the idea of a 6.7 cummins becuase it's quieter than the 5.9 cummins in the OG ramp truck.

Cummins, Duramax or Powerstroke it = better MPG maybe over 10 then.

how do u run a 4l80e on that?? trans controller? i have a 89 dually tbi with a th400. debating if i swap it to card and or add overdrive because its having a lean condition. just re did the trans and intake gasket oil pan new manifolds deleted the smog still have egr. now have a lean conditon. maifolds got cherry hot and smoked the wires. dropped the timing to 8 degrees from 10, runs better but falls on its face. think its a timing issue. going to swap in a new o2 and tps and see whats up . has new plugs cap aand rotor stock base half of the distributor

That's pretty awesome but I bet that low compression 454 would like timing more up around 34 or so total mechanical. HEI's are so easy to modify. I grind the tips of the weights with a little curve and then get a recurve kit and put in the light springs. The HEI in my GTO has 25 degrees of mechanical advance and has run it's best E.T. with the initial set at 12 degrees. If you get some more advance I'm betting on 10 or 11 mpg with that excellent 4L80E!

What if you put a Cummings 12v in it with automatic transmission would you get better fuel economy? If you only got 9.2 miles per gallon on the gas engine with that new transmission how about cummings diesel engine automatic transmission an engine swap?

next: EFI + taller rear end ratio + proper aerodynamic cab spoiler + enclosed rear wheels. >> 13mpg?

Needs more chicken lights on the box and running boards. Light up Squareforce One!

Ditch the old school wing of on top and fab a fiberglass aero fairing for the roof of the cab.

That's great. I've an 03 avalanche with the 8.1. One tool box has the basic tools sets. The other is fluids and jacks. My average mpg is 10.

Vaccum advance does not go away at WOT! !
Vaccum port for distibutor is above the throttle plate and vaccum there increases as you open throttle !!!
Basics, baby, basics.

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.

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.
