Hello

I´ll maybe buy this truck in next few days, its has a slant 6, 727 tranny and np205 transfer case. Dana 60 rear axle and dana 44 front.

Do you guys think that this engine is good for this truck? I live in iceland and somtimes get alot of snow, Somtime i would like to put a "38 tries under but maybe somthing bigger. It would not be a dayly driver but im gonna fix it up tp be really dependable, because i will use this truck when the terrain is to hard for a normal car.

The engine is 100% orginal, what can i do for the engine to get more out of it?. Im gonna put headers on the motor but is there somthing more? I want to start with tunings that dont need alot of more gas

What would you all do? should i swap it out for a v8 or should i work with the slant 6, where can you buy performance parts in the slant 6?

thanks
Tomas

p.s. the owner has to heat the engine up before driving because if he goes directly on the roads and the engine stops he says its almost impossble to get it running right after, so he has to wait pretty long until he can start it up again, how can u fix that kind of a problem?

Greetings! I think you may be our first poster from Iceland.
Sounds well-equipped.
Yes, the slant-6 engine—if it is in proper repair and equipped correctly—will work well in this application.
Lots of things. Proceed carefully and ask lots of questions; there are many parts and modifications that are sold as performance improvements for the slant-6 that would be poorly suited to your low-RPM torque requirements.
No, put Dutra Duals instead! Headers are a perfect example of the kind of part that would not serve you well. The Dutra Duals will work a lot better for you than headers (better engine running, better fuel economy) and you also get to keep your intake manifold heat, which is going to be very important for the kind of service you intend to use this truck for.
Yes, but first we'd need to know how the engine is equipped right now. Can you find out whether this truck was originally built for export, or if it is a US/Canada model exported after it was originally first sold in the US/Canada? Take a look under the hood and see if you can find a vehicle emission control information label.
That will be pretty easy to fix. The exact fix will depend on what kind of carburetor setup you wind up with, but you will be well served to buy and install one of the Electric choke kits which replacees the not-very-well-designed original automatic choke with better, more adjustable equipment.

To keep your intake manifold is good. But is the flow as good as in headers? Never seen this kind of a exhaust manifolds before, I read the text and looked in some of the hyperlinks, I would probably not use the orginal exhaust pipe in anything, would just get a 2" pipe from where the Y pipe ends.

This is the basic setup right?: Dutra Duals - Y pipe (ends at 2") - 2" pipe
I think it was originally built for export because it was registered in 1982 here in iceland, but i really dont know, i know the VIN number though. But when i get it, ill try to find what u told me.

These electric choke kits, Do they come with some carburetors? Would it maybe be best just to buy another after maybe some time, for example 4 "cbbl" (dont remember how you write it) with some choke kit in it?

Thanks
Tomas

It's wrong to think that more flow is always better. The headers you're thinking of may offer higher potential flow capacity, but only at very high engine speeds you will never encounter in your truck. The Dutra setup is much better for the low-RPM torque your application requires.
You can do it that way, or you can run two pipes.
What is the VIN number?
A 4bbl carburetor is definitely the wrong choice for your truck application! Here again, you are thinking about parts that are used to create high-RPM racing engines, when what you need for your truck is low-RPM torque. That means either a well-tuned 1bbl or a 2bbl carburetor, a carefully-selected camshaft installed thoughtfully, some ignition system modifications, perhaps a set of Dutra Duals...

I second SlantSixDan, Dutra duals, and a 1bbl with electronic choke. great setup.

Okay, i bought the truck, and i know it was built for export, but what does that tell you?

I have ordered a manual for this truck and i will have it in few days.

I took two pictures of the engine, but i maybe will take more. Here are they:


Red: Is that somthing that you guys have seen before? the owner told me that some previous owners were trying to mix a air pump...
shouldnt i just take it out?


Green: Those hoses are just lying there, Some are connected in both ends, but some only connect one end, and the other end has be sawed off and few days ago the hose you see on far left, started to leak cooling water or somthing... The end that is loose is supposed to be connected in that air pump.. All very strange

What do you guys say..?

p.s Where can i find engine "power" curves photo.. u know that shows you how much torque or hp are going to wheels at diffrent rpm

What is the truck's VIN?

In the more southern latitudes where it tends to get uncomfortably warm, vehicles are sometimes equipped with something called "air conditioning". It uses a freon (ultra low boiling point liquid) with a high/low pressure system. If you look at your heater control panel, it should have extra options like AC and MAX. Perhaps this would be unnecessary in Iceland. It could easily be removed. Just be careful as the freon is under a significant amount of pressure. You wouldn't want to get it in your eyes.

Im gonna do a compressor test on the engine before i spend any time and money on it.

I have a compressor monitor. (you take the spark plug out and so on......)

What should this monitor say if the compression is still good?

With the carburetor's choke and throttle plate blocked open, and all six spark plugs removed, you should see at least 7.6 bar / 76 kPa (110 psi), and the cylinder-to-cylinder variation should be no more than about 10%.

If you will open the hood and look at it, you will find an identification plate or label that contains information about the equipment your specific truck was built with. If it can still be read (it might need cleaning), can you post a clear, sharp photograph of it?

Your VIN decodes this way:


1B7KW24E8BS100332

1: Built in USA
B: Dodge
7: Truck
K: Gross vehicle weight between 3 629kg and 4 082kg
W: Power Ram pickup truck 4WD
2: 250 series
4: Conventional cab
E: 3,7 litre 6-cylinder with 1v carburetor
8: VIN check digit
B: 1981 model
S: Built at Warren, Michigan plant #1
100332: Serial number

Yeah, the sticker is there and ill see if i can get a shot of it. I have taken the broken a/c system out of the car and it all looks better now under the hood.

What i want to do now is:

#New exhaust (Ill probably go with the Dutra Duals)
#New filter, Is K&N filter a good choice? for low rpm performance?
#And then ill check how the carburettor thats in the car now works and finetune it or ill buy another one 1bbl or a 2bbl, how does age handle carbs? this one is pretty old......

There is somkind of a plate under the carb, see picture below, what purpose does it serve, cant i take it out?





I havent done the compression test yet

Here are photos of the sticker on the hood




click on pics for larger ones

Tomas

Don't bother with an K&N for low rpm.

A good stock filter is fine. (WIX prefered, basically any name brand (and although I don't like fram oil filters, fram air filters are fine))

What kind of a filter is this? http://www.dutra.org/doug/doug-sl6-exha ... l-dual.jpg (im really lost when it comes to filters) Does it get air just all over the engine compartment or what?.... If sombody knows alot about diffrent filter setup, please share some info..
