Over 25 Years Later, Finally My 71 C-10 Truck Build

[hgs_notes]

I got the tranny cooler hooked up to the lines and I think I have the leak fixed. I re-did the flare on the line, it may have been slightly out of round. Anyway, no leak as of now. Still need to paint it yet.


Looks like it was made for it.


I keep tweaking the ECU adjustments and it keeps getting better. Finally got a burnout and wasn't even really trying, just happened.

Now I just need to get the fans hooked up and continue tweaking it and it'll be running strong. Just about time to order a windshield.

cool deal!


...and yes....you still need to paint that cooler

It's been a few days since I did much with the truck. Monday I started working on the fan wiring, didn't finish but knew what needed done. Today I had a conference call with my boss (I have a home office) for my mid year performance review (No worries, I'm above average ). Right after I get off the phone, I lose internet service, which is required for virtually all I do in the office. Looks like an excuse to head out to the garage.

Started with the wiring to the fan controller and had no juice. Oooooops, seems I left the key on for a few days. Battery completely done. It was taking a charge though, so with power from the charger I was able to hook everything up and test it. Works fine, but I need to attach the temp sensor to the radiator somehow. Thinking about bonding it on the tank by the battery with some kind of epoxy or JB weld. I'll need to route/shorten/tie off the wires yet, but essentially it's ready to go. Later on I'm going to change the fan controller to a dual fan set up that stages them at different temps and do a better job hiding everything.


Since that was done and the battery was still charging, I decided to hook up the tail lights. I got the light assemblies in the other day. Hooked up the harness and had a couple working lights. But I knew the grounds weren't connected yet, so I pulled the sidemarkers and hooked up the grounds. A while back I had already cleaned up and painted the light assemblies. At that time I added ground wires to each assembly, which also just bolts on to the bed with the sidemarker ground wire. Works great and very easy to do. Anyway, the tailights all work great, except the reverse lights. I'll have to figure out where the switch is and fix that. Blinkers work also, at least out back, as does the license plate light. Picked out the best of the lenses I had, cleaned them up, put in the new gaskets and screwed everything down. Looking good.


Notice the license plate bracket is installed on the bumper. Can't hardly see my gas tank now. That's one advantage of the shallower square 73 and up blazer tank. The disadvantage is that I think the signal for the guage is wrong. Mine pegs high and I know it has a good ground. Something else to fix. Oh, and at least some of my dash lights work. I'll wait til dark to check it again so I know which bulbs need replaced. Punch list is getting shorter.

Punch list:
Front bumper top brackets
Polish other wheels
vent windows
door glass, felts and chanels
heater box
fat mat
seat bolting plates
adjust e-brake cable
wire tie wiring on frame
headlight buckets, clean and paint, adjusters?
seat belts
tailgate letters
rearview mirror and visors
door panel upper trim and panel screws (need to order)
kick panel vents, paint and mount
rear window and windshield
wiper/washer test (will probably need new pump)
horn
inner fenders (need new nuts, paint bolts)
gas gage reads high
manual throttle

Yep, just knocked off a couple more from the list. I'm picking some easy things to make it seem like I'm really flying. Got the dome light in and working, dash bulbs all good (but the right blinker arrow stays on, hmmm), heater control is in, speedo and e-brake cables hooked up (need to adjust the e-brake tension though).

Today I just worked on wiring and some tuning. Finished up the fan wiring, made a junction block from scrap aluminum for the ground wires, bought and installed a new underhood fuse block.

First the ground block. Paid a buck to a local machinist for some 1/4" x 2" x 4" hunk of aluminum. Drilled a 5/16" hole in the middle for the main mount bolt to the radiator support. Drilled 7 #7 bit holes around the edge and then tapped them to 1/4" thread. Got some nice 1/2" long 1/4" pan head screws and some lock washers and called it done. I have a few washers between the block and the radiator support just as a spacer. A thicker block wouldn't need them.


Here it is mounted. It's actually straight, but the parts along it have angles making it look crooked. Battery hides it anyway.


The fuse block I got because I had too many leads coming into that little one terminal thingy on the fender. This one has 6 fused terminals and fits in there just right. I didn't wire the ECO for the EFI into it because it has a separate inline fuse, but might move it later. I'll also split off the fans later when I redo the relays for them. It was about $20 at Napa.


Also got the fusible link on the passenger side replaced, but don't know if the gage is working yet. Bought a new temp sending unit to install and see if I can get my temp gage to work. Will install later, the truck is cooling down for the night.

Cooling down you say? That means it's been running. And running wild. Burnouts around every corner of my block. I keep adjusting the EFI leaner and it keeps running better. Even with the new locker and a swap to 3.08 gears from 3.73, it turns them over no problem, even into 2nd gear and I'm not even trying. Hope this video link works, just putting it away for the night.

Nice!!! Looks and sounds good

[Dieselwrencher]

Very cool! Congrats. That has to be a great feeling to get it running and finally get it running good! Keep at it, it's coming along nicely!

I'm pretty happy with it right now.

Thanks! I'm keeping on keeping on.

First pic is for VA72C10.


I did get the temp sending unit in, and the gage works. Bonus! I didn't have the right connector end for the sending unit so I went to the local junkyard this morning and 2 off so I have one for the Jimmy also. Soldered in a piece of wire since mine was cut about 3" from the harness plug and there it is. I put it on the passenger side of the block so the wire could be routed with the starter wiring and pretty well hidden. Kind of makes you wonder why it wasn't that way to begin with. Oh and with the temp gage I could check the electric fan operation. Test sat.


What else did I do? Let's see, finished the cowl install by adding the screws (finally found them) so now the hood seal doesn't slide around. I need to put a few shims in the front edge though so it stays even with the hood a little better. Seems like I'm almost done working under the hood, so...




My grill is kinda crappy, considering all the work done to the rest of it. It'll have to do for now. The top edge was really scratched up and gouged, and figuring I really had nothing to lose, I took a file and sand paper to it. That anodizing or whatever is not the easiest stuff to sand though BTW, but I was able to at least smooth it out and polish it up. I could go back and just get all the anodizing off the top edge and repolish it and it would look ok. As it is now you can see the transition from chrome to polished aluminum so it sorta looks like patina'd chrome, if you can imagine that. I'll buff up the rest as much as I can, paint the headlight areas again and call it good enough for now.

The wife says I have to get new stuff because the parking light lenses don't match, the grill is scratched and pitted, the inner is cracked, etc. I didn't argue but it'll have to wait until I either sell some of my blazer parts or other funding comes along. The bumper cleaned up alright, but is also scratched up some. I need to find those top of the frame bumper brackets also. Probably in the attic.

Time to get some glass back in it and take a real ride in it.

Punch list:
Front bumper top brackets
Polish other wheels
door glass, felts and chanels
heater box
fat mat
seat bolting plates
adjust e-brake cable
wire tie wiring on frame
headlight buckets, clean and paint, adjusters?
seat belts
tailgate letters
rearview mirror and visors
door panel upper trim and panel screws (need to order)
kick panel vents, paint and mount
rear window and windshield
wiper/washer test (will probably need new pump)
horn
inner fenders (need new nuts, paint bolts)
gas gage reads high
manual throttle
Cowl shims
fan and headlight relay wiring

[VA72C10]

Awesome! You painted the cooler!









And the rest of it looks great. When you do buy a new outer grille consider the chromed ones they now make....to me the anodized ones always look dull against a chrome bumper...and they now sell a chrome one for the same price as the aluminum...

[hgs_notes]

That's the plan man.

[VA72C10]

The only issue I have with the chrome ones is they don't make them with the black around the headlight bezel area....but that's easily fixed with a little scuff and paint or some black vinyl....

Started the day trying to figure out the mounting for my seats. Here's the dealio, they fit in the all the way forward position, but it is back against the rear window. So they can't be adjusted forward any more. This isn't really a problem for me or my wife because we don't need them forward. Just wanted to see if there was anything I could do other than mount them further forward and adjust them back. The problem with that is the little bump in the cab floor for the front mount. If I mount forward of that, then I'd have to clearance the seat mount on the driver side, blahbiddyblah. Anyway, said the heck with it and just decided to mount using the front holes and leave them that way. It's comfortable and the seats will still slide forward for access to the rear. I didn't finish that, so I'll post pics later when it's all done.

I did get the passenger door glass installed. Short sentence, lots of work. Mostly the clean up of the parts. They had over spray on them, lots of dirt, lubed everything up, etc. There are a couple threads on the board here on how to do this, but I didn't see any mention of the window seals and felts along the bottom of the window frame and when they should go in on this process. I ended up pulling the vent window back out because the seal just didn't want to fit with it in the way.

Steps I took:
1. installed the regulator
2. installed the rear vertical channel, but just a loose bolt at the top rear, leave the bottom 2 out
3. drop the window in, slide the rear roller into the window channel, then slide the window to where the front roller fits into the notch in the channel
4. install the new window felt in the frame top and rear window frame
5. install the new felt in the vent window channel
6. slide the vent window in, but not all the way. Leave it up a few inches and tipped back. Tip: make sure you put some masking tape in the area where this fits in the door and at the top of the window frame. (yes I had a couple knicks in the paint)
7. cut to fit the window frame bottom seal and felt (Mine were a little long)
8. snap in the outer seal
9. Now finish sliding in the vent window, install the screws. The reason for leaving the rear channel botton loose is so the window will slide back some while you do all this.
10. Snap in the inner felt
11. install the screws for the bottom of the rear channel, tighten everything up, remove the tape and there you have it.

I don't think I forgot anything, but if I did I'll update this later. I used this thread as a guide: http://67-72chevytrucks.com/vboard/s...ht=vent+window Also used my service manual for the procedure.

I lubed all the rollers and the roller channels with some white lithium grease, and the regulator gears also. The rollers are available as a replacement part if you need them.

[VA72C10]

Nice progress!

[67chevy1series]

looks good!

[hgs_notes]

I got the glass in the driver door today. That was about it. No pic, looks like the passenger door in a mirror right? Found the brake light switch is cockeyed and needs to be adjusted, reverse switch not hooked up but I need to change it out for the correct truck switch rather than the van style it has now. This morning I was looking at my first pics in this thread and realized I didn't have the bolts in the front bumper top brackets back then either, which explains why I can't find them now. Good thing I have a parts truck to get them from.

Windshield is scheduled to go in Thursday morning. I need to get the seatbelts ready and the front lights and get it ready for a cruise.

[VA72C10]

Good idea leaving the windshield to the pros...I've heard too many stories of guys breaking 1-2 before ending up paying someone anyways

Cruise....did you say cruise? How sweet will that be???

That's right. Even the body shop that painted it wasn't interested in doing the windshield install. They were relieved I didn't ask. I wonder if I can talk the installer into staying to help with the Jimmy windshield?

The cruise, aka the shakedown run, will be sweeter than honey on a caramel roll. I already know it's drivable and will idle for quite awhile without overheating. The brakes work and I'm pretty sure the lights will be good. I'm not so sure about the charging system though. I switched to an internally regulated alternator, converted the wiring myself, and have a used alternator from an unknown car. I had it tested before install, but who knows if everything else is right. I plan on packing my tool kit, jumper cables, fluids, some of the most common sized bolts, fuses, etc. and hope for the best. If I'm comfortable with it over the weekend I'll try and enter it in the show/swap at St Peter for the following weekend.

Didn't get much time today, but I got the seat belts ready to bolt in. They were in pretty bad shape. I cleaned the belts up and think they came out nice. I'll see in the morning after they dry. One of thwe retractors was jammed, so I pulled it apart, cleaned it up, reassembled and it should be good now. The retractor covers were all bent out of shape, but a heat gun works wonders for working the kinks out of the plastic. Really easy, just warm up the area you want to straighten (or bend) and when it gets soft and pliable, just move it around to how you want it and then cool it with a damp rag. I use a putty knife or flat edge of a screw driver or spatula to use as a flat then just press the rag against it to hold it flat while it cools. Another tip is that when you push the cover over the retractor and it doesn't seem to want to fit right, just get it on as best you can, then use the heat gun again and finish the fit with it warmed up, then it will cool into the right shape over the retractor.

I'll post some pics tomorrow of how they turned out. The male ends for the buckles are rusted on mine. I'm going to see if I can get someone to stich new buckle tabs into them later. For now I just need them clean and functional and legal.

[hgs_notes]

Pics...These started out as stained, oversprayed, deformed, and jammed.

[VA72C10]

Those look very good! Nice work!!!

By the way....did you lock the thread so only you and I can post?

Thanks! C'mon, diesel posts also, and some others. But I know I can always count on you for a or a . I know people are looking though, it's getting up there for views.

I'm here too. The details you accomplish just leave me speechless.

Great work.

Yes you are and I appreciate the feed back. I'm pretty excited to get the glass in today. I might just bolt the license plates on and see where I end up this afternoon.
