84 Crewcab...AKA..Patches

[J.C. Corbett]

I have an 06 5.9, and my dad has an 08 6.7. They're basically the same pickup, both 6 speeds. Mine will outpull dad's given an equal amount of weight, but driving dry, it feels as though his, unencumbered by emissions, would eat my pickup alive. The feel of the 6.7 stock is that it's being overly harnessed. I'd be interested to see one with a mechanical pump. Watch out.....

 

[Mark Nixon]

My vote would be to p pump it if you have access to a p pump front cover and the rest of the stuff. Though the flexibility of the cr stuff is nice...

The "wormy" part is twofold:

Worm 1; The timing case is not a "bolt on", holes have to be added, some removed and some moved around, though with the right tools, it's @ an hour long process.

Worm 2; Unless you cut the stock intake off, ANY Commonrail head will NOT clear the injection pump.
The beauty of it is that the 1998-1/2 24 valve head WILL clear either pump (The VE still requires "minor" clearancing) with the stock intake casting, PLUS that's where the mechanical injectors come into play, the "VP" engine is still semi-mechanical, so the injectors work the same as any 12 valve ones will.
The spray angle is also off (@ 8*), but there are custom tips for those injectors of all variety of spray angles.

Mark.

I'd love to have a 6.7 Cummins! My '03 5.9 is great, and could be a monster in it's own right, but the EGR/DPF deleted 6.7 would be sweet.

I'd like to find an older, 50's Dodge truck, make it a crew cab and put it on my chassis.

How about a sweptline 68 Dodge crewcab...you know it makes you tingly in the right spots...

This would have been my second choice on dodge crewcab if I didn't find a 80's one I liked.

And Mark...I have to bow to your extensive knowledge of all things dodge diesel...you sure know a lot about obscure details that most only ponder.:hail:

 

[Mark Nixon]

Cow, I tend to look at the dark side of things to try to find the light side, in case you hadn't figured that out.
I'd be happy as a pig in crap if only I had a place to let my creativity wander, much like Kirk does, I suppose.

Speaking of "all tingly", my nuts are tingling for that old crew cab you posted! :giggedy:

Mark.

cow id drop a big D in that without batting an eye....

on that note..my boss tells me he found a running MARINE 6-71 for 150$...god what shoulld i do with it.....

 

[Dr.Jass]

That would depend on what engine's beneath it.

 

[v8440]

My guess is that the marine 6-71 IS the engine.

 

[Dr.Jass]

Shows what I know. I thought it was just a blower. :doh:

 

[Mark Nixon]

4-71, 6-71 and 8-71 are the engines a certain blower were mounted to.
I forget the manufacturer of the blowers, but they had their own model designation, though people back in the day only referred to them by the engines they were removed from.
Of course not all Detroits were blown, either.

A Detroit is a 2 stroke gutless wonder, but they sure sing a sweet song, un-muffled and trying to pull a load up a hill.
Gutless or not, they were one of the standards of the American diesel industry for decades.

Mark.

 

[Dr.Jass]

So it is safe to assume there were also 10-71s and 14-71s, as I've seen those blowers in the past? Serious question.

 

[69.5CUDA]

well when you get into those you start at the 6v71 8v71 12v71 16v71 and the monster v24..i dont recall a 10v or a 14v ...v designating is a V engine vs a straight..thus why i said a 6-71 as its an inline 6......if memory serve the 71 was dropped for something like 53 or something like that for NA and something else entirely if they were turbo the only reason i know the v's so well is that i know they always shared heads from the 6 or 8 to save man handling weight as well as be able to use shared blowers from them as well

but i have a love for the big nasty work horses that moved the world

the inlines was 1 2 3 4 and 6..all of which i belive could have been has with the supercharger...i thought they made a straight 8 but i find no referance....oh yeah and the turbos fed INTO the BLOWERS!!!!!!

want a real giggle

a 6-71 is 426CI

 

[Dr.Jass]

Weird. I've seen 10-71 and 14-71 blowers... or at least that's what I was told. I knew the "71" denoted the displacement of a single cylinder in all cases for some reason, but I thought they had different names for the engines themselves. I'm always learning. Thanks, 69.5.

Now, here's my next question. There used to be this ridiculous '50s Ford at the local mud bog. It was a Detroit 2-stroke V8 with a blower, no turbos. It sat on an Oshkosh frame and axles, and (at least) 56" tires. I heard it alternately referred to as a 318 or 392 Detroit; never an 8V-71 or 568 or anything like that. Any ideas? The bellow from that thing could be heard from miles away and the black smoke was incredible. It was awesome to watch run (he had zoomie headers) . He always made it through, but never quickly.

 

[thrashingcows]

Sounds like one of the old detroit screaming Jimmy's. I drove a couple of those motors...not fast, made tons of noise, lots of grunt. You couldn't drive those motors and tranny all pussy foot like...they used to say you had to drive it like you just slammed your hand in the door, and now you want to take out your anger and frustration on the motor and tranny. They were right...

Here's one in a tractor pull...made me giggle...

[video=youtube;dw2vd_ERVEU]http://www.youtube.com/watch?v=dw2vd_ERVEU[/video]

 

[Mark Nixon]

IIRC the designation (318 or 392), referred to un-modified horsepower output on the 8V-71.
Years and years ago, I distinctly recall pulling a SuperCharger off of one referred to as a "318 Detroit", but at that time I didn't know a thing about them.
All I recall is that it was a V-8.

Mark.

 

[Fishy]

We have the exact same kind of tractor up at the shop. Just nowhere near as beefy as that one though.

 

[69.5CUDA]

correct the 318 was the HP same with the 392 it was the HP tag designated to ALL of the 71 series engines they were often and still even some of the cats are just refered to by the HP tag not the actual engine info

i actualy blame the truck manufacturers for the engine HP being refered to as what the engine was

 

[Mark Nixon]

I can see it now, the 6.7 being referred to as the "Cummins 350 B", because it's a 350 HP 'B' series engine.
"Hey, I see you have a 350 in yer Dodge."

Mark.

 

[74DartSport]

We had a Trackmobile in the shop a few years ago with a 4-53 in it. Shop had the motor rebuilt. When it was rebuilt something was done incorrectly (seal in blower IIRC) and on first fireup it ran away. I remember that thing screaming in the shop, guys running away and one tech calmly standing there looking at it for a minute or two, then blocking the intake and suffocating it.

 

[thrashingcows]

Well I can't believe I forgot to mention that I re/re'd a Heater and A/C unit from a newer dodgre ram (1993) and then swapped it into the crewcab.

New'er unit ready for a re/re...

Old unit torn out of truck...

 

[thrashingcows]

New'er vs old....

Also discovered why I didn't have much heat...turns out the vacuum line running to the water shut off valve had worn a hole in it. So it was only getting a minimum of vacuum to open the valve and let hot coolant into the heater core.
