Hay...this is a DISPOSIBLE Society... an itty bitty 4 banger in a 1/2 ton will LAST...

...2-3 years, maybe ?? That's IF you never ,ever haul anything in it !

SSON raves about his Dodge PU with 3L eco-diesel..until you ask about MPG pulling 4T of dump trailer..then he change the subject FAST !

 

Well I try not to live in the past but still seem to compare current to past events.  Does this sound similar?  Like when a 75hp tractor with a natural aspirated 301 cu in engine was replaced by a 80hp 200 cu in engine with an intercooled turbo engine?  Same as now they had advertisements showing the increased torque out of the four cylinder engine and so on.  I will say this, the 6080 is a nice tractor to drive but there is a reason I own a 185 and not a 6080 because when it comes down to hard pulling that 185 will dig its heels in, smoke a little out of the exhaust and go, where the 6080 will need to be shifted down and given some slack.  I know of a number of 180 and 185 that went to 10K hours with out and over haul and most 6080s that I know of have been overhauled at least once.

Don't know the LONG TERM, but though I would give it a try. Got 85K on the motor. Gets 22 MPG at 55 MPH and 19 PMG at 65 MPH... 4 door crew cab... Rated to pull 13K trailer......  who would have guessed ??

 

 

OH... and its got a constant FLAT torque curve and a  375 HP output.

OK, I must be adft today but...

I remember reading an article that a formula 1 engine at 14,000 rpm had similar piston speed to a chevy 350 at 5400 rpm

The F1 engine is spinning 2.5+ times faster than the 350 so HOW can 'piston speed' be similar ?

Because the stroke is shorter, and the connecting rod is longer.  Trigonometry, sir.  Max piston speed occurs at 90 degrees.

That all being said... my whiz-bang F250 has a 6-speed and something like 6.2L in it's V8.  They rate it at some stupid horsepower... and while that all may be true on paper, it ain't worth feces in real life.

First off, if you want that power, you stomp on the pedal.  It thinks about it for about two seconds, shifts two gears, then another two, then back one, then screams, then it pulls... way too hard... so you let up, and it's basically off.

Next... If you're rolling up a gentle grade, and it starts losing speed, you give the throttle a little push, and NOTHING happens.  Give it some more... NOTHING happens.  A little more, and now you're down substantially in speed, it does the above dance, beats you up, and by that time, you're over the top of the hill.

Now... it gets 11mpg on the interstate.

I have an '84 Chevy P30 Step-Van... a Frito-Lay delivery truck for those who don't recognize... a P-30 is a one-ton forward-control chassis used in all sorts of delivery trucks, including UPS, Dolly Madison, etc, and came with a wide variety of power and drivetrain options.

Mine originally had a 6.2L, and Frito-lay dumped ALL of them in lieu of a Cummins 4BT about 3 years after taking shipment.  Mine has a Dana 70 rearend, 4.56 gears, 10,000lb GVW, running 19.5 duals in back, singles in front... and when I'm driving it somewhere, it's full-to-the-limit with speakers, amplifiers, drums, music stands, lighting, etc., for my band.  With that little diesel, it was peppy from 0 to 45mph, perfect for in-town delivery. On the highway, limited to 2400rpm, it'd go 54mph.   It got a good solid 14mpg.

I yanked the 4BT three years ago, and dropped in a 1976 Buick 455, and a TH400, for a variety of reasons, one being the 4bt's governed speed being somewhat incompatible with interstate velocities, the other being that said 4BT was 'not included' with the sale of the truck, but was on-loan until I found more suitable power...

Anyway, I chose the 455 Buick for some very simple reasons... first, being that they're inexpensive to obtain from guys who yank them out to build demo derby cars.  Second being that they rolled off the lot sporting over 500 ft-lbs of torque from a little over idle, clear up to 4000rpm... Yeah, they were only identified as being something like 205hp... apparently horses were bigger in '76...  but that was substantially more than the Cummins diesel, and with the ability to easily spin to 3500 on the interstate, was well capable of unreasonable and improper considering the breadbox aerodynamics.

Suffice to say, the P30 breadbox has NO difficulty getting it on from any stoplight, or any on-ramp... or passing a truck... headwind or not.  I don't have to wait for a downshift- simply pressing on the foot-feed yields very immediate results at ANY speed... no downshift-upshift drama, no crazy noise... just torque... pull... go, and NOW.

Oh... and that breadbox, loaded to the gills with gear, gets 12mpg.  With 4 years of technological improvement, my brand-new Ford F250, loaded to same weight with tools, can't beat the driveability or fuel economy of a breadbox with a worn-out Buick 455.

The problem is, that these engineers are spending all their time behind computer screens, not steering wheels.

 

....and so did Sierra, and so did Siverado.....

 

Must be factory orders.  Only the Ram showed different numbers.  Ya see what you want to see....

 

  

Good one Tbone!

Warn made an overdrive unit for your Willys. Bolts right on. Gives you a 75% reduction,so 4.88s become 3.73s. Makes truck a 12 speed !! Made for both 4 bangers and 6es. Needs a differnt 'input' gear ,rest is the same. If (IF ) you get one , be SURE to ADD oil to the tranny ! And inspect the 'oil delivery tube' !!! If you don't, well, you'll burn out the 'sun' gear going down a long ,steep grade, with 1 1/2 tons of prime top soil in the box...

sniff, sniif I miss my old Willys
