I've heard that before, but the lack of duration and the fact that the 1st gen cams are weaker in the area behind the first fournal and like to break when driving a turned up p-pump. I'd use a later cam when doing the swap.

Today I took the body guy more paint and picked up my seat. He had a couple other things painted for me. The radiator support, hood latch, and hood guide plate. I guess it is progress. :lol:

My lutch is supposed to be here today, conversion lines next week, and some other misc stuff may trickle in later. I did get the RH door lock installed and it works! Now it is getting time to install door panels. Does anyone else think a layer of plastic or some thing will help eliminate road noise and stuff?

the only thing plastic will do is keep moisture from getting to the card poard dood panels from the back. some of th guys on the 47-59 board are using a peel and stick roof patch product that would work if you put it on the inside of the outside door skin.It dampens vibration. I will see if i can find the thtead.

the tar/bitumen based roofingstuff will stink up a storm when the truck sits in the sun the real dampningmat like brown stuff and dynamat has less smell and is more resistant against heat in general , you could just put clearcoat on the back of the doorcards that should seal them up just fine

The inside of my doors already has a coating on them. I am more interested in keeping cold air and dust from entering the cab via the doors. I might put some insulation in there I have around. I'll post pics if I do it.

I forgot to add my new to me clutch showed up yesterday. We carried in my steel bed floor and my buddy Mathew cut it to get ready to extend it so we can get the bed assembly started. Pics later.

Maybe body putty. it stays soft and seals good.The stuff that is it comes in a box about a foot long and has sevral layers of cords about A1/4' in diameter. some car companys used it between the dood and a plastic sheet.

Man I had not checked in in a while, Truck is looking great.

before too long you should be driving it. It is going to be a one of a kind for sure.

Sadly looking like it will be probably a year and a half before I get to get my 72 cummins project going again.

Ahhh, I hadn't heard of them breaking.

Have you tried any of the Hamilton cams? The street one seemed appealing to me for having a rowdy DD and be able to pull the world.

Thanks, that stinks you won't be able to work on yours for a while. I know how that goes. This truck has been off and on for a few years. Hopefully I can get it wrapped up before June. :waah:

Yep. Been using Zach's cams for a while. I have his 181/210 in my Vette, we have several 181/210's running in street trucks, we also have some 200/220's going too. We also are a dealer for Colt Cams as well. The prices on Hamilton's cams are really scaring people though.

I know what you're talking about. They always used to use like a black butle type of stuff to hold on a sheet of plastic. I haven't decided what I'll be doing yet. I didn't mess with it at all yesterday. Working on a worn out poor dodge right now. :lol:

Here are pics of the bed work beginning.

We also found out that apparently the bed mounting holes aren't the same on this frame. So that makes me think that the Longhorn bed mounting holes are spaced differently than the standard 8' beds. I always assumed the rear half would be the same. I was wrong. :lol:

I've been watching all the guys on here who are shortening beds, studying how they blend in the body curves where they removed the sections... Its gonna be cool to see this bed go the OTHER way! Are you gonna weld the factory longhorn seams?

I thought about welding it and smoothing it out. But I want it to look some what original. Most people probably wouldn't catch it beeing a Longhorn with out the seem. I like it there too. My luck, I'd weld it and that area would be the only place that body work would crack or I'd get hit there first. :lol:

Thanks Mike. It is slow going. How ever, I am working on the engine while I sleep. So maybe by the week's end I'll have it close to beeing ready to drop in.

On the first gen vacuum pumps, yes you can. I did that on my corvette. I used the vacuum pump to drive the PS pump so I could run hydraboost brakes.

You can get the newer style vacuum pump set up and then you won't have to go without a vac pump. 92-98 should be same vac pump. PS pumps, there are 2 different styles. A tear drop shape housing, and a round. Then there is a 1 return and a 2 return for hydra boost set ups.

Re: Finally starting my Longhorn 4x4 conversion
 
Thanks Ryan, that's good to know.i want to use a hydra boost I really like the one I used on my 42 jeep. clears the buick V 6 and has lots of power with a good solid feel.
a vacuum pump may be a good idea for the AC. Its sort of design by the seat of the pants.LOL

Re: Finally starting my Longhorn 4x4 conversion
 
This weekend in between some other projects, I had some help and managed to get some box sides bolted on! Now I'll have to decide if the LH box side is going to be used. I think the one from my original bed is nicer. So we'll see. This metal floor swap isn't going to be as bad as I thought it was going to be!

Sorry about the mess. We've been cleaning up out side since it's been so nice and now it's supposed to rain all week so we had to shuffle stuff around the storage truck. :lol:

Here is the new phase of this truck. I don't have a common rail engine any more, and I want to get into tuning on EFI live. My brother happened upon a sweet deal a few weeks ago and now I'm going to build a common rail and put it in the Longhorn. Here are some misc. pics.

http://i181.photobucket.com/albums/x...n/DSC00581.jpg
http://i181.photobucket.com/albums/x...n/DSC00578.jpg
http://i181.photobucket.com/albums/x...n/DSC00577.jpg

The thing in the plastic bags is my block. The turbo is a 76mm HT60 which will be my primary turbo in my compound turbos.

Right now I have most of the big pieces I need for it. Here's what I have for it right now.

05 Block with fresh hone and deck job.
12v crank
181/210 Hamilton cam
06 ECM
05 engine harness
05 CP3
05 injectors
04.5 donor engine for hard ware
12v connecting rods
4 good 05 pistons

What I'm lacking to get it together
Rings, and bearings
Gaskets and seals
2 05 pistons
100hp nozzles
Some misc wiring to get the engine running.

I plan on getting the stuff for it soon so I can try to get it running soon. I was going to buy new pistons for it, but the pistons I wanted were $1000. That's going to have to wait! :lol:

Hey ryan nice build Im not much into diesels but what is a common rail?

ryanroo 03-19-2012 10:25 PM

Re: Finally starting my Longhorn 4x4 conversion
 
common rail refers to a pressurized fuel rail that is common to all injectors. the injectors are cycled by the computer instead of mechanically via fuel pressure. it has been the dodge system since 03. all current diesels run this type of injection now i believe, in light trucks anyhow.

so, you cutting me a good deal on the 24v with the p-pump swap? haha

ryan

1985-GMC 03-19-2012 10:26 PM

Re: Finally starting my Longhorn 4x4 conversion
 
They're trouble that's what they are! lol EFI live should be fun!

Haha no in 03 the common rails came out, they use a CP3 injector pump in which one line fuels a "rail" then the computer controls when the injectors open instead of pressure like on the mechanical systems.

Lookin good ryan! When you cut out a piece of bed floor from a donor are you going to just get the front 15"s or so, so you only have to weld up one seam?
