Next potential problem is that the fan on the 366 is mounted high, offset and it is a really big fan! The radiator in the 89 was a full two inches taller than the 68 and tucks right up against the bottom of the hood. In fact, these rubber pieces seal the hood to the radiator in order to keep all of the air flowing through the radiator rather than around it (notice the extra holes so that the seals can work with any of the various width radiators they offered):

Attachment 1652374

Even though the hood gets significantly taller right behind the radiator I was still concerned that the fan or fan shroud would hit the hood. In this picture you can see the stock 68 shroud on the right and the one from the 89 on the left. As you can tell the fan on the 68 dipped a bit below the bottom of the rad and the one for the 89 was higher, larger and actually hung past the edge of the rad on the driver side:

I was thrilled when I test fit the 89 shroud on the 68 and fount that it bolted in to the same holes in the core support as the 68 and had it in the proper orientation for the fan, just a bit high and narrow:

WOW! I just saw that this thread has been viewed over 20 thousand times, thanks everyone! :thumbs:

OK, back to the update, So the shroud was in place, now just carefully close the hood and see if it clears. With the wheel wells still out it will be easy to check it out from underneath. So as I very carefully lowered the hood it stopped going down on the passenger side when the hood hing hit the corner of the battery :dohh: :cuss: :banghead:

Attachment 1652380Attachment 1652381

Had I mounted the tray a half inch forward or to the right this would not have been a problem. So frustrating. Anyway, I can fix that later, removed the battery and sure enough the hood can shut and clear the fan and shroud :bann::bann::bann:

I have worked out most of the shroud modifications in my mind, but that will start next weekend.
Thanks for checking in and stay tuned folks!

Thanks for hanging in there deer hunter!

Re: 68 C50 Looongbed pickup build
 

Good update there Richard. And the fence! Wow, well done. Straight, tight, tops of posts uniform height...Did you have to drill for some of the posts? Did you pile up the rocks along the fence?

Re: 68 C50 Looongbed pickup build
 

Thanks Doug.

Yes indeed. I bought a 9 inch rock auger for the pipe posts that we set in concrete and a 2” “puff auger” for the tee posts; seen in action here: https://www.youtube.com/watch?v=jA-VzFhsAjo&t=4s The top of the hill was solid rock, every post had to have a hole drilled.

Yes, I restacked a lot of the old rock fence rather than just have a dozer shove it out of the way.

Re: 68 C50 Looongbed pickup build
 

This weekend I made some progress, I now have a fan shroud. As seen in the previous posts the shroud from the 89 was too tall and not wide enough. Fortunately I had a spare shroud identical to the 89 (it came from the school bus that donated the power steering box). I was able to hack it up and along with an 8 foot long 1/8" thick 2x2 angle aluminum I was able to fabricate a shroud. I didn't stop to take pictures often enough, but I'll share what I have.

First is a shot of the shroud that is getting sacrificed. All cleaned up and ready to cut:

Attachment 1653995

I took three inches off the passenger side of this one and removed one inch off of the one that will go on the truck. In the next picture you can see that piece added on. At the bottom I trimmed down a piece of the angle to fit and pop-riveted it on. Because the two pieces were different heights I relief cut the main part so that I could pull them in to line. Then I cut a piece of the angle in half in order to get a 2 inch wide flat piece and pop-riveted that long the seam pulling them together as I went. Here is how it looks:

Attachment 1653996

Here is the back side:

Attachment 1653997

And here you can see the angle reinforcement at the bottom. The oblong hole is where it bolts to the core support.

Attachment 1653998

More to come...

Re: 68 C50 Looongbed pickup build
 

Along the top I cut off the lip that was sticking up and pop-riveted a piece of angle flush with the top sticking down where it can seal up against the radiator. Here you can see the original lip sticking up:

Attachment 1654001

Here is the angle Riveted on as seen from the top:

Attachment 1654002

And from the back side:

Attachment 1654003

Here is the piece that I added to the driver side, the curve was fun to cut:

Attachment 1654004

And what you will see with it installed, this will get it perfectly even with the edge of the radiator.

Re: 68 C50 Looongbed pickup build
 

Looks great ,a lot of handy work there.

Re: 68 C50 Looongbed pickup build
 

Finally I covered the relief lines on the front side with masking tape and filled the cuts from the back side with quick drying epoxy:

Attachment 1654008

While that dried I reworked the battery tray. As I mentioned last week, the hood hinge was hitting the battery. I ground the welds and popped the tray off, then reworked the reliefs in the box tube frame and moved the tray as far in board as possible as well as a bit toward the front. I also took this opportunity to add a filler piece to cover the gap. I think the before and after shows that it looks better than before. If it still hits I'll be pissed!

Just checkin in. Looks great! My trucks goin good. Until i cant get fuel. Wiring harness works. Just no fuel to carb. Fml lol

Re: 68 C50 Looongbed pickup build
 

I made some progress this weekend. One significant problem I was facing was that the wider radiator was touching the steering box. Not pressing against it hard, but hard enough that it would have eventually rubbed a hole in the tank. After much head scratching and a few attempts to gain clearance (I even tried to move the body forward on the frame. FAIL!) I finally gave in and had the radiator shop notch the tank.

Attachment 1662913

While they were at it I had them add a new petcock to the passenger side tank (the original petcock was in the way of the steering box as well).

Attachment 1662914

I used a 2-1/4 “ hole saw to make a hole in the bottom of the core support to access the drain. A bit of sanding and some Rustoleum and I'm ready to install the radiator…

Re: 68 C50 Looongbed pickup build
 

Next up I bolted the radiator in. A quick check showed that while the hole I drilled wasn’t exactly centered it would work.

Attachment 1662921

Next up was the lower radiator hose. The lower hose for a 68 with the 366 is obsolete and no longer available. The 89 setup wouldn’t work because the new radiator is about 4 inches wider to the passenger side and the hose setup couldn’t fit. The 89 actually used two short pieces of rubber hose with a steel pipe in between. This was because the alternator belt is really tight to it and by using steel they could keep the needed clearance. I ended up getting a lower hose for a 78 c60 366 which was all rubber but also did not fit. By cutting off part of the steel pipe and part of the 78 hose I was able to fabricate a working solution. Here are the bits I cut off:

Attachment 1662922

and the hose mocked up

Attachment 1662923

Here you can see how close the alternator belt is to the steel pipe. There is only about ¼” clearance!


Attachment 1662924

I also spent MANY hours making up the oil cooler lines. I didn’t feature them in any pictures specifically, but here is one showing the upper line:

Re: 68 C50 Looongbed pickup build
 

With the radiator in I needed to finish up the fan shroud. All that was needed was to add some way to attach it to the upper radiator mounts. I had a tiny bit of my angle aluminum left. I used it to make the two mounting tabs and pop rivet them on and then hit it with a bit of paint:

That is all for tonight but there is more to come (foreshadowing :D )

Re: 68 C50 Looongbed pickup build
 

Looking great .

Re: 68 C50 Looongbed pickup build
 

Thanks Flashed!

Did I forget to mention that after topping off the coolant I DROVE THAT *****!

(That is what the foreshadowing was :haha:)

I don't have the dash cluster in, so no temp gauge. Because I had no way to monitor the temp I only drove it 4 or 5 miles, but dang it was good after all this time :thumbs:

Re: 68 C50 Looongbed pickup build
 

Once again your resourcefulness is inspiring. Your simple "lets not over engineer this problem" approaches to all the hurdles this project tosses at you are refreshing in this billet everything day and age. It's good to see someone building a truck instead of assembling one.

Re: 68 C50 Looongbed pickup build
 

Richard, looks good and I make trips to the back rooms of the autoparts stores looking for combinations of hoses all the time. I need that special rubber hose bender thingy :)

Re: 68 C50 Looongbed pickup build
 

Great solutions Richard!

Re: 68 C50 Looongbed pickup build
 

Thanks! While it is nice to have a robust aftermarket, there is a lot of cars that seem like they were picked out of a catalog.

I didn't know they made anything to bend rubber hoses, man would that be handy.


Thanks Doug, I hope all is well with you.
