Looks good. You ready for a bunch of rain the next few days?

Does your truck have a cable driven tachometer? That cable is driven by the same gear that drives the oil pump is Why I ask if you have one and if it is still working. The oil pressure sender is on the driver side very rear of the block. Following the procedures to verify the gauge and sender...

OK. You know what you are doing. That makes a big difference in the answer. The last GEP I had apart I used these guys for bearings, rings, gaskets and TTY head bolts: https://enginecomponents.com/ That engine was surplussed and threw the #1 rod during a compression test. Turns out it was...

Thank you for watching my videos. Glad they helped. Adding a turbo to either engine will get you real close to what the F-250 could do. BELOW 50 mph. If not surpass it. To get better than that, you will have to start messing with transmissions and axle ratios. Both of which take away from the...

I didn’t mean to give that impression. A turbo on a 6.2 is an amazing thing. However, even with a turbo you will not keep up with any diesel made in the last 25 years and probably not any V8 and most V6 gas trucks with the same load made in the last 20 years. Your M1028 is limited by gearing...

Are all of those things bad on your engine? If so, getting a used pull out might be cheaper and surer. Normally if bearings and pistons are trashed. Then, the block and crank might be shot as well. The GEP 506 block and I can’t remember the casting number of the heads are unique to the...

What are your end goals for the truck? I ask because the 6.2 has the small throat combustion chambers. While the 6.5 has bigger throats. If you are just going to be cruising around at 50 mph empty and don’t want to slow down on hills and maybe accelerate 0-50 .001 second faster then putting...

I just got done playing with this for a video that will publish this coming Friday. The link to my channel is in my signature.Everything is post 2 is spot on. The balancer line and the pump line under the 4 bolt window need to be exactly lined up at the same time. Then, the red tooth will be 1...

Take it for a drive. 40-45 mph is the speed where the squarebody becomes a barn door in the wind. Try to get at least that fast and just drive.

How many hours do you figure the truck has idled and just moved slowly since the last time it went down the highway at speed for at least 20 minutes? The generic term is wet stacking. Basically a diesel that isn’t being worked will start to smoke. Black, blue and white. It will also just not...

Wow, you did some searching to find this old thread. Good job! My first thought when I saw your thread yesterday was I haven’t done this in a squarebody so I won’t comment. My next thought after I had clicked away was that there are several threads on https://ck5.com/forums/ where people have...

It reads as if you have tried two different used Injection pumps. Is that correct? It also reads as if the fuel rate has been turned up on at least one of the IP units. Black smoke is too much fuel for the air inside the cylinders. Without a turbo the only ways to get black smoke is with a...

American General Products was just a few years. I want to write sometime 1968 to sometime in 1970. Then it became AM General. My 1971 is an AM General.

Glad it performed well.

I can’t tell from the pictures which engine you have. Here is an article with pictures that shows the biggest difference...

Welcome to the fun. The data plate from the Injection pump you posted is for a 6.2 diesel engine. The 8 3 1 means 8 cylinder .31” plunger. A 6.5 diesel injection pump would have 833 in that section for a .33” plunger. I don’t know what engine you have but you have the injection pump for a...

Congratulations. I thought production ended in 1988. Your truck probably isn’t a 1997. If it is a 1987 then it could have the dual circuit brakes if it was an Air Force truck. Looks like a fun project.

I agree totally. I logged in just now to say the same basic thing you did. Well put!

I just spent a few minutes looking through a -10 TM. I couldn’t find THE word. However, my experience has been engaging the front axle switch while moving works just fine. I have never tried on pavement. Since I also have a sprag automatic engagement truck and have had the steering wheel...
