I don't believe so, Jonathan, but if I get the chance, I will once again attempt to enhance the aerodynamics???

Wait... aren’t you running a different recurved distributor now that you didn’t have back in 2016? Pretty sure I’m running the one you had back then... 😉

I believe my mirrors are type 5, but you wouldn't know it from my gas mileage numbers.

I know the feeling. Even though my truck has the bigger mirrors, it never got much more than 10 mpg with the 300 C6 and 2.75 rear axle ratio.
Now that I have the 5.9 cummins and nv4500 in front of that same 2.75 axle, it gets well over twice the mpg it did with the gas/auto combo, and pulls MUCH harder with very little pedal input.

If I didn't have stuff going on, I would love to join into the MPG test. It would be very ironic for the oldest truck, and largest displacement engine, to win....

What's bad are two things, my 1977 F150, 300 engine, C4 trans, 3.25 9" rear and the big tow mirrors would get 16 highway, and about 13-14 in town. Darth, with a very low compression EFI converted 460, E4OD, 3.55 gear and the same mirrors, gets a solid 10, but on long higher speed runs (70 mph) can get 12.5 - 12.7.

Paul - Friday the 20th is the plan, I believe. And, it'll be Mr. Bass in Skiatook, to Hominy, north on 99 to 11, and back through Barnsdall to Mr. Bass. BE THERE!

Doubt I'll be able to join in. However, if I can, I will.
2 questions though. Where is Mr. Bass, and do they have diesel? If not, we may need to alter the plan a bit...

The Sinclair about a mile from my house: https://www.google.com/maps/place/Mr.Bass/@36.3690993,-96.033768,17z/data=!3m1!4b1!4m5!3m4!1s0x87b6e73310092051:0xa9d2100b47ee9035!8m2!3d36.3690993!4d-96.0315793.

And they have diesel, for sure. Filled Janey's car up there many times.

Re: Gas mileage test [revisited]

I have stopped in there a few times in the past while arriving/leaving your house. Never paid attention to the name on the sign.....

I'll have to see how things are looking as the time gets nearer, and I'll let you know if I can join in.

Well, Cory [Rembrant] is sending his "old" Type 5 mirrors to me, so they will be in place for the 600+ mile drive to and from Skiatook. Thanks, Cory!

These old mirrors needed a place to go, and I'm happy to see them spend some time on I-40 for Bullnose MPG testing! They might decrease drag, but they'll also decrease your rear view...lol. I just cleaned them up. They're not perfect, but they'll look just fine at 60mph.

Those mirrors look great, Cory!

Stay tuned as it will be reported, here, either by Gary while I am returning from the show, or me, later.

I want to thank Cory, publicly, for the Type 5 mirrors. They arrived yesterday and look very nice! This weekend, they will be installed in preparation for the drive to Skiatook, OK, next week.

Cory was also kind enough to include a New Brunswick license plate which will proudly be displayed on the wall of my "man cave"..

Thanks, Cory!

Over the last few weeks, I have been talking about the Garagemahal Truck Show and the upcoming gas mileage test [revisited] with a group of men at a local breakfast restaurant. Today, one 75 year old man proceeded to give me some advice:

1. Drive with tailgate down or removed.
2. Add Lucas gas treatment to every other tank.
3. Use 100% gasoline.
4. Use higher than 87 octane fuel.
5. Replace air filter with a K&N filter element.

I thanked him.

Supposedly the tailgate down idea was debunked by Myth Busters.

As for the octane, some say higher octane than needed can actually hurt MPG. Their thinking is that fuel with a higher octane rating burns slower, but I don't think that is correct. The octane rating really determines how volatile a fuel is, meaning how prone it is to an explosion rather than a controlled burn. On the other hand, it is possible to use fuel of such a high octane rating that it is hard to light off in a low-compression engine, and that would cause poor fuel economy.

In fact, Blue gets better MPG with higher octane fuel. That's because it has a knock sensor and the computer can advance the timing more w/o knocking with the higher-octane fuel.

How about 8.4 to 1? And, no knock sensor?

High octane fuel would be a waste at 8.4:1. But I doubt it would hurt the MPG.

David,

MPG aside, let me know what you think of the mirrors for actually seeing behind you!

PS: For "Man Cave" discussions, you can note that New Brunswick is where the Bricklin SV-1 was built during it's short lifespan in the mid 1970's. They were powered by a Ford 351w for at least part of the production run. Not sure how often you guys see them down south these days, but I see one every now and then in the summer months.

https://en.wikipedia.org/wiki/Bricklin_SV-1

They still show up for sale as well. This one below is listed for sale in New Brunswick but is actually in Maine.
