July brought the biggest expenses to the truck yet.

First a brand new set of 255/85r16 Falken Wildpeak mud tires. They really do fit the look I was going for. I didn't want anything too wide.

Next I started on the most ambitious project I think I've ever done. Building a flatbed from scratch.

The main channels are 3" c-channel and crossmembers are 2x2x1/4" angle. The outside edge is 3x4x1/4" angle. The best thing I did for this project was the Evolution cold cut saw.

Mid July saw the new shop come together really fast. Then I took a few weeks off to finish electrical in the new shop before they spray foamed it.

Finally the end of July I moved the truck to its new home.

August has been a busy month so far!

For starters, My trusty white 98 3/4ton chevy developed a bottom end knock on it's 290k mile motor :waah::waah: This has pushed me to get the 49 on the road.

I feel like i've been working on the bed forever now. Here's more pictures. It's pretty much done besides the wood bed floor and eventual stake sides.

Then came a lot of frustration building a brake light switch bracket that I didn't take pictures of and getting the turn signals working. I finally took it for a real, road legal test drive last weekend. I still have a host of things to complete, but it's very roadworthy. I had some trouble with reverse in the transmission, but a band adjustment solved that. Here's a picture from the first offical gas station visit.

Last night I swapped the 195* thermostat and 210-195* fan switch for a 180* thermostat and a 195-180* fan switch. My gauges indicated that the thermostat was actually opening about 210 and the fan was turning on at nearly 220. Now hopefully I'll stay below 200.

Thank you! I'm getting excited to actually be able to drive this truck soon. It's been in project hell for nearly 5 years :lol:

Ahh, wiring, the party that seems to go on forever! Nice work.

Time for my yearly update :lol:

Well it hasn't quite been a year but getting there quick!

I made a bracket for the front bumper! it sticks out a little more than factory, but it looks like it's made for a winch if I ever get there

https://americanmusc1e.com/Photos/db...25551810~2.jpg

I finished the bed! This is cheap pine 2x10s with some Thompson's water seal stain. It's held up surprisingly well so far. The 2x10 planks are attached like you'd do a trailer.

I started driving the truck a lot! The big flatbed comes in handy!
https://americanmusc1e.com/Photos/db...IT~2%20(1).jpg

Two main complaints remain. The truck overheats very easily, and the interior sucks.

October stayed pretty busy! We hit a couple car shows and did an overnight camping trip with a tent on the flatbed. Was pretty fun!

November more driving pictures. The truck was still running hotter than I thought it should be. I had reinstalled part of the inner fenders and switched to a 160 thermostat. The truck also still rides pretty rough unloaded. It wants 500lbs on the back otherwise it's still pretty bouncy.

I don't know if i posted about it before, but I added a GPS speedo. It works great! I need one for the C10.

December and more driving and hauling with the truck. The water temp just isn't right. it's not overheating, but it's not right. Put the truck going up a moderate hill and I can gain 10 degrees of water temp in 20 seconds. I broke down and bought a new larger aluminum radiator and a new water pump. It made no difference.

January my cousin came up and we fabricated a new tailpipe section out of 3.5" aluminized tubing with some v-bands and new hangers. The truck had a 3.5" turndown under the bed right past the cab, and the interior noise is so much better exiting behind the rear tire out the side now. I also put the carpet in and recovered my seats. I still hate the factory seats. https://americanmusc1e.com/Photos/db..._231952969.jpg

February I did more interior work. I cleaned up and painted all surfaces under the carpet and seat and painted them and added some fatmat. I also did some jute under and behind the seat as well as installed a 4x4 Posi-lock kit to be able to lock and unlock the front axle instead of leaving it locked in all the time.

March I just worked a lot :lol:

April I installed my wideband O2 and cleaned up the gauges a little bit. I also cut down and built brackets to install the side steps. Late april I got serious with the temperature issues on the truck. I bought a bleeder funnel and tried to bleed the air out of the truck. Every time I revved the motor up, I'd get a ton of air bubbling up but no drop in the coolant level. It passed two different combustion gas tests for a bad head gasket, but on a whim, I hooked shop air up to my compression tester on each cylinder and let it sit for 5 mins. I learned that I had four cylinders where the valves were leaking down badly. And I could also get bubbles in the cooling system if I left shop air on cylinder #5. :smoke:

I broke down and ordered a brand new set of EQ cylinder heads and the associated gaskets. And a very tiny camshaft.

May was just a lot of cleaning parts and putting the top end of the motor back together. I did install new valvesprings in the heads for the cam. I also may have done a little work to the bowl and port matched the new heads. Not that it matters on this truck. It just bothered me. :lol: I have put the truck back together and taken it for a quick spin. I don't have enough time with it yet to confirm that the overheat problem is entirely gone. I sure hope it is.

Mid month update! The engine is back together. So far no overheating. Fingers Crossed that it's fixed.

Now I'm tackling a transmission issue that's been bugging me. Reverse is very sluggish and I can't get the low/reverse band adjustment right. I ordered a reverse band strut that's 0.100" oversize, but when I actually got mine apart, it's nearly 0.350" shorter than my new one. I had to drop the valve body to install the strut. Then I had to install the valve body twice because I left out the accumulator spring the first time.


While I was in the transmission, I replaced the pan because my original is dented and possibly not straight on the flange. The new pan has a drain plug as a bonus. I also helicoiled a stripped thread in the pan bolt flange.

Just got the transmission back together last night. Reverse feels more normal now.

The transmission works great! I still have an overheating problem though. I'm currently running a new temporary radiator relocation to see if I can get more air flowing through the radiator at speed. So far the results haven't been that great. i just ordered a higher flow electric fan to see if I can make some improvements.
