The bottom of the hood was the only other thing that has been painted so far. He claims he's ready to paint the front fenders, hood, and cowl now. He doesn't want the bed until the front half is done. He also said he painted the core support as well. I have to wait to gather some more money to go buy paint so it can be knocked over, I mean applied to my parts.

Re: Finally starting my Longhorn 4x4 conversion

Nothing else get a non intercooled VE and swap it to p-pump. they have the better pistons to play with any way. A 24v is hard to beat once it's swapped too.

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.

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.

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.

Re: Finally starting my Longhorn 4x4 conversion

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.





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.

Re: Finally starting my Longhorn 4x4 conversion

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

Re: Finally starting my Longhorn 4x4 conversion

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.

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.

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.

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.

Re: Finally starting my Longhorn 4x4 conversion

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.

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.

Re: Finally starting my Longhorn 4x4 conversion

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.

And I thought I was the only one that ran into stuff like that

Re: Finally starting my Longhorn 4x4 conversion

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?
