Newbie, help me get started

Bought a highboy today, just trying to figure out what I have.

From the PO it is a 69 with a 67 cab installed. Cab includes the doors so it is registered as a 67. I was told it is a 390, but not sure. It is an FE block, that I can see. I looks fairly stock including intake and 2BL holly. Manual 4-speed tranny with granny.

Here are the numbers for the axles and t-case if anyone can help me there.

Rear Cover: Dana 42799-1
156 2
Rev N
05 03 94
Rear Housing: C30255
60
L

T-Case: G29-15-4 (All I could find)

Front Tag: C9TA-B1
603130-1
4.09
Front Housing: 44 6CF


Thanks in advance,
Bob

Something else,

The vacuum plate under the carb has to large lines running from it. One to the brake booster which seems correct, but the 2nd one is running to the breather cap on the valve cover. That doesn't seem right to me, wouldn't that act like a vaccum leak? I thought the idea if the breather cap was simply to minimize pressure buildup in the crankcase. Any thoughts?

Welcome to the Highboy club. They are great trucks. As for your numbers and such, I am not much of help. Too tell if you have a 390, you will want to check stroke. I can't remember what the spec is for a 390 vs 360 vs 352, but you can search some of the older a threads or someone smarter than me will be along to give you the stats. One of the best gurus here is numberdummy. He has forgotten more about Fords than most people will ever know.

By the way, I am going to put a '72 cab on my '70 highboy in a few weeks. That ought to be fun.

Good luck with your truck.

welcome,it seems as if a lot of the 67-72 highboys have parts from various donors,im wondering if a lot of owners destroyed the orig. bodies off-road and swapped bodies off clean 2wd trucks. 2 of the 3 67-72's that ive owned have gone this route,FE motors from other applications,better still with 4bbl factory intakes,later model transfer cases,power steering,the list goes on. Im well aware of the fact that my current 72 F250 might have parts from countless other vehicles,and that its not worth a thing in collectibility,but i like it,and thats what matters. there are some exceptionally knowledgeable people posting here,and its likely they can answer most questions you have

Thanks guys for the replies. Any thoughts on the best way to measure the stroke without taking the pan off? Via a sparkplug hole I assume.

My wife figures the beast is ugly, she can't see true beauty. My main reason for picking this one was that the drivetrain, and chassis tested out very solid. It runs strong and rides pretty good. It does wear a coat of many colors but I can live with that.

I'm a backyard mechanic, wiling to take on almost anything but we just sold our house in Atlanta and haven't found what we want in Knoxville yet so I'm garageless and feel somewhat naked. Over the last few months I sold my 66 beetle and 98 Ranger mud toy and had to put our 67 Mustang coupe in storage in GA (Its almost finished and didn't want it sitting outside anywhere). But I couldn't resist and had to get another toy even though I don't have a place to work on it....... soon I hope.

I think you can check it through the spark plug hole. Here is some info I got from another thread.
Your best bet would be to measure the stroke through a spark plug hole to give you a rough idea of what it could be (this would either show if is is a 360 (3.5" stroke), a 390 (3.78" stroke) or a 410/428 (3.98" stroke))
Tell us what you find out.
Here is a link to the thread.

Your right there, something is not correct. The carb base plate is suppose to go to the PVC valve in the valve cover (passenger side, normally). The brake booster should connect to manifold vacuum, normally at the back of the intake manifold. The breather cap on the other valve cover should connect to the Air breather so it can get clean filtered air. Or it can be a filter cap (no hose).

from what I see, you have a Dana 44 in the front with 4.09 gears & a Dana 60 in the back. Can't tell the transfer case. But a true highboy should have a divorce mount transfer case. Generally a New Process 203(full time/ chain drive) or a NP205(part time/ gear drive).

Thanks for the input.

Haven't taken the time to measure the stroke yet, not a big deal cuz it is what it is. I will worry about it more if I need to pull it apart or decide to do a rebuild.

I verified the vacuum from the back of the intake and baseplate are running to the PCV valve and booster.

Thanks for the axle info, that is what I was looking for. The t-case is divorced, it has 3 driveshafts. I'll have to get under there again to see if I can find any other identification.

Thanks again,
Bob

the NP203 is a cast iron case, and weighs about 150lbs. Plus, you will not have an option of 2WD.

Most likely the NP205 then, if its original. I missed that point from your first post.

Thanks for taking the time to clarify.

Another Q. I noticed that on the front of the block at about 2 oclock, relative to the water pump, it is stamped with 352 and under that a 44. Is it safe assume that I have a 352 block has been swapped into this truck?

Was the 352 and option in 67-69?

Thanks,
Bob

Don't go there that's a can of worms when it come's to those numbers BLOCK #'s. Well it's in the FE family. To check the stroke put #1 ATDC and #4 is at the bottom .
A welding rod works good and a marking pen .Make a small mark on the rod when placed into #1 cyl push to the edge of the v-cover gasket lip, then do the same thing with #4 marking the rod in the same manner you did with #1. Ok now measure the distance between the two marks. If 3".5=352,360 3.7/8=390, 3.9/8=410,428. That transfer case could even be a dana 24.....hope this helps.

Thanks Orich. Followed your method and the PO is in the know, It measured 3.71 inches so I'll call it a 390.

Also found the VIN on the frame. Looks like it is a 70 frame built in Nov 69, with a 67 Cab or drivers door at least. My title is based on the door and therefore registered as a 67 F100 2wd. Doubt it is worth trying to change the title, just kinda entertaining.

Thanks again to all.
Bob
