Today i found this marking on the front window.
The newer one says VEH. MAIN. painted in black.
The older one says Commander Det 29.

On the hood it says Us Air force For official use only.
But i think the hood is not original.

Anyone know what they mean?

it was not unusual for individuals to mark the windshields when a vehicle was assigned to a particular person or position, such as commander detachment 29 or command sergeant major and so on. us air force and for official use only are standard usaf markings and should also have had the air force reg number, like 67K 369 or similar. The air force put the year and type of vehicle first then the number. 67 being the year, k meaning tactical vehicle 369 the unique reg number. admin vehicles such as cars and buses were labeled with a B after the year.

The oil pump gear needs to align spot on with the camshaft or you will not be able to effectively set the timing once the motor is put back together.
That's the problem I have with my engine right now. The Military did not index it correctly.

Oh thank you.
The next question, why does the oil pressure going up to 60 psi when I trying to start with the switch off?
Or when I'm trying to start it cold?

Not very much have happened since the last time i updated.
I have installed new camshaft bearings, that's all.
I have decided to rebore the cylinders because they where out of limit.
Have been looking for 0.10 over pistons but i only found one who sold them for 240 EUR, way to much when i can buy 0.20 pistons for 80 EUR. (Truckpartstrading.nl)
So i waiting for my pistons that will arrived tomorrow i think.
And going to let a machine shop rebore them next weak i hope.

I have now start to put the engine together and noticed some things.
First of all is the New camshaft, must be bent or something because when i spin it it will kind of stuck so i have to use some force to spinn it.
The Reconditioned Crankshaft i bought on ebay 0.10 underzise , it is installed but i sensing a gap when i moving it up and down.
In three tappets i sensing a gap in.
I dont know what to do about the tappet problem, can i buy overzised tappets anywhere?

How are you "sensing" a gap? Is the crank .010 under and using the correct bearings for that size? The cam should turn with very little resistance. I know you put in the cam bearings yourself, what did you use to install them and are you positive they went in straight? Cams are cast iron so they do not bend, they break.

Well you feel it not sens, sorry i wrote it the wrong way. , imagine a worn out piston pin,like that .
Yes i did put them in with a special tool. the thing is that i can turn it a half revolution with ease until i must use force to turn it.

Is there a fuel pump mounted to the engine? That would explain the feel in the cam. Other than a cam lobe interfering with something I cannot see what could be happening. If the cam were somehow bent it would be tight all the way around because of multiple bearings. The only other thing I can think of is the end play may not be right but again that should be a consistent tight or loose. I have built a couple hundred engines and I have to say I have never been able to feel a loose bearing, at least one that had not spun and had massive clearance. Did you plastiguage all of the bearings, both crank and rod? That is a must for any new build.

I tried the old camshaft and it runs perfect.
Then I checked it with a micrometer and noticed that the camshaft is bent.
I measured it to 0.1-0.15 mm. It shall be between 0 - 0.01 mm.

That would had to have been a manufacturing defect then. Or poor storage. This falls into a category of parts that are called NOSR parts. New Old Stock Reject. There are tons of old parts out there that were rejected for one reason or another at the manufacturing level all the way down to body parts at the shop level. Sometimes these parts did not get sent back and destroyed, they just sat in a dark old warehouse for years until someone found them and said...................... LOOK! A NOS QUARTER PANEL FOR A HEMI CUDA!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!. Now they sell those NOS Rejects for monster amounts of money because nobody has made them for years. And they have no idea there is anything wrong with them.
I got a NOS flywheel for my mutt and all of the holes were drilled .006 off to one side. ALL of the holes, mounting holes to the crank, to the flexplate and the center hole. I could get it on by putting the bolts in pushed tight to the side of the hole. BUT, the whole flywheel is going to be .006 off to one side, that is going to vibrate so bad it will knock the glasses off your face. I have heard of others who found the same problem putting them on and some that even ran them that way. NOSR. Keep it in mind, nobody knows where these old parts came from. Your cam probably was not heat treated correctly or it was stored somewhere with something sitting on the middle of it for a long time.
