This is the ID number for the label (tag) itself, it has nothing to do with the engine!

Engine related numbers are in the 6000 group, emission and fuel related numbers are in the 9000 group.

Since this number is 9C485, it's not related to the engine.

Thanks for Schooling me on this Numbers.. I did do a Tune up on the Engine and It runs like a Sewing Machine... It did start making a High Pitch Whining noise and I am afraid that might be the Bearings in the Water Pump, But I'm not sure it could be the Power Steering Pump as well. The Belt is maxed out as far as adjustment goes and seems a bit loose. I am going to replace it with a Shorter One and see if it works out, the same thing is happening with the Alternator Belt as well. I did get to drive it a bit yesterday and it drives really nice. Has a Few rattles that I need to fix but it seems to be a pretty tight driving Truck. I did find another Tag on the inside of the Drivers Side of the Hood and it says the Original Engine was a 400. The one in it now is a 351M. Has plenty of power and runs really nice.

So I have an issue with my Turn signal on the Back Left Tail light. The Brake Light and the Turn Signal are very Dim and I have already took the Ground off behind the Light assembly and Cleaned them and the surface they are bolted to with no change in the Brightness of the Lights. Can anyone help with what else could be the problem with just the Left Rear Light being Dim. Thanks in advance for any help.

I found on my truck that I had very weak grounding happening throughout the entire vehicle.

What I did to solve the problem was make my own ground connections that I knew were better than factory. I believe in total, I've added 4 common grounding points throughout my truck.
1) Frame to front clip
2) Frame to cab
3) Frame to box
4) Negative battery terminal to frame.

These have helped me immensely over the last 2-ish years to resolve grounding issues when I couldn't find what the heck was going wrong. I still have gremlins in the wiring, but 95% of my issues disappeared into thin air once I did this.

6 thing's I used:
1) properly sized / clean / new ring terminals
2) an existing hole (cleaned) in the frame
3) bolts + nuts + lock washers
4) dielectric grease
5) 12 gauge wiring I had lying around (tested it for resistance before using)
6) shrink tubing

At first, I thought I had solved all my issues by cleaning and re-using what looked like good existing grounds around my truck. Once I had everything clean and lubbed with dielectric grease, I took a piece of wire and ran it between 2 pieces of clean metal (frame + box). I saw my tail lights go from bright to brighter immediately upon touching the new wire between the two clean points; this is how I found out that my existing grounds, although clean, weren't so great after all.

Arron,
Thanks for all the Information. I am going to go pickup some Grounding Straps and Attach them to all the Body Parts from the Frame and also Run a Ground to the frame from the Connecting point on the Engine Block to the Frame. I use dielectric Grease and its the best stuff for keeping good and Non Corroded connections in these old trucks. I hope this will help but the Previous owner liked to use those Crimp type Blade Connectors and most of the time they did nothing but cut the wire and make for horrible connections. Im going to take all of them out and replace them with Heat Shrinkable Crimps so I will know they are getting good connections. Thanks again for your help, and it makes perfect sense.

Interesting. What's the GVWR of the truck? Is it a swapped in engine, or maybe just the valve cover? Does your fuel gauge say "unleaded fuel only" on it?
Reason I'm asking all those questions is because, as you can see, that engine decal clearly states "non-catalyst" on it. Which means that it came from a vehicle with an 8500GVWR or higher that year.

Since you say your truck does have a cat, and it would be very unusual for someone to put one on where it wasn't required (although that's something I'd do, and did!) I'm just wondering about it.
Hopefully it doesn't send up any red flags during inspection if they look for that kind of discrepancy.

Been having Oil Pressure Issues with my 351M and I figured out what it was. The Oil Sending Unit on the Back of the Motor was dislodged from the base where it screws into the top of the Block. What I figured out is the Oil Pressure Sending Unit was the Wrong one and it was too tall and when the previous owner put it in they forced it and broke the top of the unit off the threaded part. I put the new one in and there was barely enough room to put it in with the Vacuum Port that sticks out for the Transmission and the Brakes. Now the Oil Pressure sits at half deflection on the guage when its hot and about 3/4 when its cold. I was getting pretty worried that maybe the Bearings were done but I think its okay. It Runs like a sewing machine and I really like it. Lots of torque but by no means a race truck.

Looks like she will be going in for paint within the next Month or so... I am going to do a little minor bodywork to it before I send it off. This truck is really finding a place in my heart and Im not sure I will be able to let this one go... Story of My Life...

Aaron-71 05-10-2019 09:38 AM

Awesome to hear you're getting some fresh paint on the beast!

And we hear you about letting it go. Countless threads on this forum on "wish I hadn't sold it".... These old trucks are bulletproof if taken care of. New trucks aren't!

AMEN!!! Problem is I have way to many Projects and they are stacking up... There is a lot to be said for getting one and working it until its finished... I really want to Finish my Wifes 67 Mustang and I think that is going to be my main push with this 79 Going to Paint Soon.

JRB64 07-08-2019 03:56 PM

The Truck went to paint and these are a few pictures of it as it sits now at the paint shop. Cant wait to get it back... they said 2 to 3 more weeks...

Got some new pics of the Truck and its almost done at the Paint Shop...

Paul, What I found out about the history of this truck is that the original engine was a 400M and it was pretty tired and worn out. The Previous owner has a Trans Shop and he rebuilt the entire drive line in this truck and right next to his shop is a Machine Shop and they had a 351M in there that had 20K Miles on it so he swapped it in rather than rebuilding the original 400M. It runs so nice, the only thing is it is very quiet and I like a little rumble from a truck, not real loud but a nice rumble. I was told that Its best to keep the Single exhaust but to go with a different muffler so it wont effect the torque. They are telling me if I go with a Dual Exhaust I will lose some of my Low End Torque and also I would need another Cat. I think a new Muffler and Pipe out the Back is the way Im going to go on this one. Sorry it took so long to answer your question, I have had some life things happen and It completely took me away from trucks completely since early this year. Just now getting back into them.

No problem. Thanks for getting back on that. Hope life is running smoothly and you can find time for some fun too. Well, "fun" with the truck anyway.

Makes sense on the swap. Glad you've got the history of the truck to work with. You don't necessarily lose low end from duals. It's just how they're done. Most might be tempted to go too big and that can effect a lot of things that need to be tuned out or just lived with.
But a good single is still the way to go in my opinion. Or I even like duals run down the same side and did that to one of my Broncos. Easier to interconnect with an H-pipe/crossover that way too, which is almost always beneficial in out cases. But mainly I like having the extra real estate under the truck for other things.

That black is sure lookin' smooooooth too!

Thanks Paul, I have to tell you I am really happy with my painter. I use to do all the Bodywork and Paint but it makes such a mess in the shop that I have just found it better to let a shop do it. This is my Second paint job with this guy and I just told him this morning that I have a 69 Ranger/Explorer that he is going to paint Its Original Signal Flare Red above the Bump and Below it Black. He asked for a little time between Projects and so I told him I could put it off till Next Fall. I am going to get the 390 Rebuilt and have the C6 gone through. Its a nice truck and I look forward to making it my Daily Driver.
