The Shop Truck

1971 Chevy C20 with a custom flat bed.
The sniper was fairly easy to install and set up and "tune", but it still needs some work. It still isn't happy when you first start it up, but I should be able to clean that up. It needs more drive time as well to do more learning.

With all the upgrades there is definitely a noticeable increase in power, not bad at all for a goodwrench 350.

Now if the 700R4 would just shift right I'd be happy, it seems like every time I set the kickdown cable it moves again and starts shifting weird...
 
Well crap, life got in the way and I haven't updated this thread in 6 months... I'll try to get this thing caught up.

I'm still in search of some OEM style clearance lights, so that part is on hold until I can get something more appropriate.

First I'll catch you up on what I've done that I didn't take pictures of... You can see evidence in some of the follow up pictures, but I didn't snap any of the process unfortunately.

First I'll cover the bad. The new fuel injection and proper timing resulted in more power which resulted in a transmission that was extremely unhappy (the failed attempts at burnouts probably didn't help). I have no idea what the history of the trans was, and I wanted to get things done in a hurry, so I ordered up a TCI 700R4 from Summit Racing. This was the beginning of a painful process.

The new trans was installed and it almost immediately started leaking (from the pump input). Visual inspection from under the truck showed a warped flex plate. I ordered a new SFI rated chromo flex plate (why not right?) and a new input seal and dropped the trans again. Everything back together and it's leaking worse than ever, visual inspection shows the new flex plate is warped, wtf... Everything comes out a 3rd time (hooray!). This time the pump housing is cracked, I pull the flex plate off and try to figure out why they keep warping and I realise that the external counterweight on the crank is not machined properly and is contacting and warping the flex plate. The new stronger flex plate (why did I buy that again?) was strong enough to crack the pump housing and not just trash the seal. Now I had to raid my shed for parts, new/used pump housing, transmission reseal kit, and another new flex plate and we were back in action. I ground down the counterweight until it didn't warp the new flex plate, rebuilt the pump housing and put everything back together again. Finally the trans was working properly and not dumping fluid everywhere!

Now for the good. All of the glass in the truck was extremely pitted from weld/grind splatter. It used to be a welding truck, so no surprises there. I ordered new glass and rubber for the whole truck. Not pictured was the install of the new windshield and the tinted rear window, which required cutting off part of the headache rack (which looks way better now as a side benifit). This brings us up to date with what I have pictures for, so I'll start there now.

Since we live in AZ a useful vehicle requires A/C. I picked up an A/C kit through Brother's Trucks (they re-sell for Old Air). It required a double groove power steering pump pulley, I had upgraded my power steering pump to a newer press-on style when I replaced everything a while back (it was leaking bad), but we managed to find a factory application that used a dual groove pulley on a press on pump and got it installed so we could install the rest of the A/C system.

The kit is pretty clean and moves all the air boxes into the cabin to clean up the firewall.

I'm not incredibly happy with how the belts ended up, but once I switch to electric fans I won't be so worried about it.

Now that I had good working A/C I needed to plug up that fuel filler hole. Thankfully Brother's had a nice patch piece for that.

Daam dude that’s a ringer for sure.. I hate that kinda bullsh!t stuff where it sort of comes out of nowhere and ruins things and wastes insane time..
I put an OAP Setup in my truck.. works damn good and you won’t be disappointed. The brothers guys are awesome..
can’t wait to see this on the road.
 
These pictures are from June or earlier, I've been using the shop truck quite a bit between working on it. I bought the truck to help get my yard ready for the new garage I'm building, so it's getting used and the A/C works pretty good. I think there's something wrong with the expansion valve (low side pressure is way too low), but it still works pretty well and I haven't felt like tearing it apart again to fix it.
 
The next thing I wanted to fix on the truck was to make it a true flatbed. The way the previous owner made the rear tailgate really limits the functionality. Step one was to relocate the fuel filler neck. It was at the back and if I was going to have a tailgate that flipped down I needed to have it flush with the bed and not sticking out like it was. I decided to move it over to the side which gave it a nice straight shot into the tank, now it fills better and looks better.

Once that was sorted out, I cut off the old tailgate, which enabled me to move my cabover (that's for sale if anyone is interested!). You can also see in this shot that I spent a few hours with some 3M pads scrubbing the old nasty paint off and getting down to the original color on half the hood. I also scrubbed around the windows when I had them out so I could get the roof back to the original white. Unfortunately it still looks like this (two face) today since I've been so busy with other projects. I'll get back to the paint eventually.

With some work that needed done out of the way I went back and finished up the new tailgate. You can see the new tinted rear window and modified headache rack (looks way better IMO).

With the new bedside setup I can flip down any one side, or all sides. I put bumpstops in a few places so I didn't have to worry about them hitting anything important or rattling around if I drove with the sides down.

With the bed the way I wanted it, I moved on to the interior to address some issues there. The factory 3 speed shifter did not work properly on the 700R4, not to mention it was very sloppy, my wife and I nicknamed it the ouija shifter. It would start in park or reverse (not neutral) and the reverse lights came on in drive... I picked up a Winters floor shifter and a tilt manual column (again from Brothers) and everything works better (and Amber can see over the steering wheel now).

The project we're currently working on (somewhat, kinda stuck at the moment) is replacing the door windows. Back when we ordered the front and rear windows, we also ordered a one piece tinted power window kit for the doors from Brother's. It was on super backorder (took three months to show up) and when it finally did, we realized what a huge project it was to get it installed. It took us all day to get one door done only to find out that the power window regulators they ship with the kit are not the same ones they used in the video (those were stock style and bolt in like factory regulators). The regulators they ship with it do not control the front/back movement of the window properly and as a result the window will get stuck tilted forward or back slightly keeping it from closing all the way (there will just be a little gap at the front or back of the window when it's up). The window will also rock front to back as it goes up and down, which doesn't look good. I'm currently working with Brother's to come up with a fix for this (or to just return the regulators), they've been super helpful on the phone so far, but I haven't gotten the issue resolved yet. As of now we only did the drivers side and went ahead and put the 47 year old factory regulator in. It works better than the power one, but is very difficult to operate with the new heavier window. I'm hoping to get some of the factory style power window regulators and finish up this install. I'm sure I'll get some hate from the people that like the wing windows, but I can tell you this much, from the drivers seat the wind noise from the passenger side is way louder than the wind noise from the drivers side (it's not even noticeable over the engine/exhaust since there's no carpeting in the truck). Amber an I prefer the more modern look of the one piece, so we're going to keep it for sure.

We've used the truck a few times for things bigger than trips to Costco. I hooked it up with a brake controller and 7 way trailer plug and hauled 4500lbs of scrap steel to the recycler (some on the bed, some on my car hauler). Unfortunately, no pictures of that. I did snap a picture of 1800lbs of palm tree in the bed, the crane worked awesome for this, it meant I didn't have to kill all of my saw blades cutting the trees into manageable sections, I could cut it into 6 foot lengths and hoist them into the bed with the crane.

For the garage build I have to move a couple sheds, so we've been using the shop truck to haul all the contents of the sheds to a storage locker down the road temporarily. We love it, it drives pretty good and it can haul a load. The flatbed with the fold down sides is awesome and makes loading, unloading and securing the load much easier.

Looks good. What about bending a simple tube to match the cab for your headache rack? Just an idea. Do you have a link for that bed crane. I'd love to do something like that on my big flatbed and kinda set it up as a service truck for my farm stuff.
 
I got super low readings on my low side as well. I was told that was due to the efficiency of the evap core. Not sure about that because I am no ac guy..
 
Now if the 700R4 would just shift right I'd be happy, it seems like every time I set the kickdown cable it moves again and starts shifting weird...

I'm late to the party here, but 700s don't have kickdown cables, they have TV cables. TV cables controls line pressure which controls the shift points, and part throttle downshifts, full throttle downshifts.
Do you know how to properly set a tv cable?

I found a diagram to help explain it a little better, but it something like this.
Release the locking tab.
Depress the adjusting tab and move the slider back through the fitting away from the carburetor until it stops.

Release the adjustment tab.

Move the throttle linkage to rest against the full throttle stop, then release it.

Make sure it's not binding on anything.

Nice update! It is funny you posted this because I was just wondering the other day how it was coming along.

Thanks, I know it's a TV cable and not a kickdown, I was just using the wrong name, yes I know how to adjust it and I replaced the cable, it turned out the trans was garbage.

I've been so busy with the stuff on my house I haven't had the hour or so I needed to go through all my pictures to do an update. I saw people asking for pictures from BB so I finally just took last night off and went through everything and got it posted.
 
Looking excellent. And functional .

How is the garage addition going?

My contractor is working on getting the permits now and I'm working on getting everything that's currently in the way of the garage out of the way. Hopefully construction will start in a monthish.
 
The problem wasn't the TCI trans, it was the crank in my GM Goodwrench 350. The counterweight wasn't machined properly causing the flex plate to warp which caused the torque converter to shake so bad it cracked the pump housing. The shifting problems were with the trans that was in the truck when I bought it (looked like a junkyard 700R4).
 
Oh my mistake I thought the shifting problem was after you changed the trans also. I missed that we had jumped back. Carry on with your sweet shop truck.
 
The AC works pretty good, I think I'll keep it.

Yeah, I know. I think the last time I was in the Phoenix Metro visiting my older brother (Luke AFB) it was 117F under a tree. Chandler is a nice area, you're a lucky man at least I think so.
