345 vs 392 pulling power in 10 wheeler

Recommended Posts

jeeper's got it right- nil/none/negative on fuel economy. Somewhere I read 5.5 to 6 mpg. Gas is about a buck a gallon cheaper here than diesel but some diesels get better fuel economy. Takes a lot of homework to figure out the right move to make re: engines.

I have old 75 Loadstar 1700 with 404. It had 150,000 showing on odometer when I got it and never worked. We loaded it to just almost running off with grain generally grossing  27 to 28000.  Would out run any other truck I have been in. Being 17 to 20 miles loaded and then back home, was about 7 mpg. Never having driven a 392 I cannot compare. But a nicer driving truck than the same vintage GMC 6500, I have driven.

Whatcha think about this?

9370, 400 Cummins with 10 speed. Air tag axle.

Too bad it's 800 miles away...

If closer i would take a hard look at it. Already have a truck tractor version of it a couple years newer

What is the 10 speed exactly?  A Super 10?

That rig is pretty similar to the silage truck I drive for my brother.  I kinda like that old beast.  IH truck, Cummins power, 13 speed with a splitter that doesn’t work, no mufflers, and a Jake that will wake everybody up for a mile.

Don't worry about the 800 miles . She will consider it a date for her to drive her new truck home

I thought 10 speeds were for smaller engines?

We have four Freightliners with N14’s that have ten speeds. One is a Super 10. I have one Freightliner with a Series 60 Detroit and a 9 speed. Nobody likes the 9 speed in that truck though. They are all FLD120’s.

The 9 speeds are fairly easily converted to a 13 if I understand correctly, just add a box to the back of trans?

Super 10 shift pattern, split each gear, no range

We still have an old FL Century Class with a Super 10 behind a N14 redtop. Rated 525 horse

So a super 10 shifts kinda like a 5 speed with a 2 speed rear end.

But this truck appears to have a std 10 speed.

I only know enough about this to be dangerous.

My 4366 has a 10 speed behind the DT466.

My 9370 has a 13 speed behind a Cummins 350 ( I think, there's no plate on the engine).

Super 10, shift split on the side of the knob with your thumb

Regular 10sp, paddle on front (or side?) of knob, shift range with middle finger

The pic you posted of shift pattern would be regular 10sp

I think the only thing wrong with it is it's not sitting in your driveway! Go get it Ace and make the Mrs. happy.

800 miles isnt that far

I brought a FL tank wagon back from Chicago was about that. 

Twelve hours

Got to know the truck real well

Think it had a 7? speed in it with a little Cat motor

After I got it home, I never wanted to crawl in it again, and I haven't😄

But then I didn't have the missus along with me on a date either🤣

So what’s the advantage, I thought the 5+2 pattern was not well liked.

As in a Super 10?

I don't know, I got along well with this one. 

I just much more prefer the 13/18sp.

I’m not a trucker. I just drive some trucks. In my opinion the Super 10 is much easier to drive than a 2 speed rear end. They sound the same when you explain them, but the way they feel when you drive them is much different. You can fly through the gears on a Super 10. It shifts a lot faster and just does not seem as clumsy to me. Lots of guys have a low opinion of them, but I don’t share it.

Yeah but it's way  over 150 air miles and probably has a GVW of 80,000. 

I don't have a CDL.

I've bootlegged things before but I'd have to cross several states...

Isn’t there an exemption for transporting something like that that was purchased away?
