Subject: ford trucks and old ford tractors

A few years ago, I was farming with a 2N ford tractor and a 63 F-100
unibody truck with a 292 and a 4speed tranny. I dont have the farm or
the truck, but I still have the tractor. By the way, Here in the
K.C. area, we have a Ford truck factory and we have the Worlds of Fun
park. they are not very far apart eiter. I beieve it has potential for
a meet, what do you think. L. D. in K. C. 97 F-250HD

Rich, take the rocker cover off and turn the pump until oil comes out of the
overflow tube on the rocker arm shaft. Then you will know that there is oil
in all of the galleries.

Steve, better go back and read that thread again. I said I THINK the hub to
hub length of the 67-71 rear end is the same as your F1, BUT the spring
perches need to be moved. I know that the 57-60 rear is a bolt in for 53-56
and that 61 thru the 70s differs in the shock mounting. I repeat my
suggestion that you take a tape measure and satisfy yourself that the rear
end you are looking at will meet your needs. I would hate for you to buy
this rear end under the expectations your posting seems to imply.

As far as your ratio, figure out what kind of driving you will do: in town
or hiway, and the percentage of each. has a site that you can then
use to calculate what RPM a combination will give.

I will be out of town through Sunday. Any admin requests or
subscription problems will be dealt with on Monday. Please
be patient, I'll have 1,000+ emails by Sunday evening and it
will take some time to deal with them.

Subject: Re: 41 exhaust

The exhaust system you use depends on which exhaust manifolds you have
on the engine. The face of the block where the exhaust manifolds mount
is the same from 32 to 53, but the manifolds have the outlets to the
pipes in different locations. The other thing that might happen, is
that the passenger Y-pipes sometimes have less drop than a truck, and
with a truck oil pan, you may end up with the crossover pipe firmly
wedged against the bottom of the pan. (does not promote cool oil)

Exhaust manifolds
18-9430,31 1932-1936 all
40-9431, 1932-36 replacement
78-9430,31 1937-1941 all
21A-9430,31 1942-1947/8 all

As far as I know, 8BA truck exhaust manifolds 1948-1952, directly
interchange with the 21A manifolds even though they look different.

Muffler Inlet Pipe, (pass side, has entry for rt side pipe, leads to

1940-41 commercial 91A-5245A
1941 Pass 11A-5245
1942-48 Pass 21A-5246
1942-47 Comm. 21C-5246B

Outlet Pipe - Tailpipe

39-41 Pickup 91C-5255
42-47 Pickup 21C-5255B

Muffler Inlet Cross Over Pipe (Drivers side of Y, short L-shaped)

78-5267 37-41 Pass, Commercial
59C-5267C 42-47 Comm, Trucks

I still have my copy of the Green Book, so If I can look up any further
let me know.

Subject: horn button 6 volt regulator iC


Your horn button should be available from "Mid-Fifties" at 800 252 1956
The catalog shows it for $25.

The 6 volt regulator 7806T 1 amp is available from JDR Micro at 800 538
5005 $0.39 ea An alternative is a LM338K 5 amp adjustable regulator,
you would need trimming resistors to set the voltage and a heat sink if
the amperage output was moderate. However, if your 53 still uses a
positive gound you may actually want a negative regulator either a 7906
or an LM337T. Guages probably could be reversed for polarity but no way
on radios ect. If you would like schematics for the circuits contact me
and I'll forward them to you

Subject: Ford 9" and Gear ratios

At the suggestion of one of our list members, He said that a 67-71 (or
there abouts) F-100 F150 9" is a direct bolt in to the 48-50 F-1. Has
anyone ever actually done this? I found a '70 F-150 9" at the junkyard
(OOPS, Auto Parts Recycling Center) for $150, Is this a fair price?

Hi Stephen , my name is Rick . I have a 51-F1 and in the middle of this project
I bought a 9" from a salvage yard out of a 71 F100 Custom Sport for $100,
3.55 traction lock complete from drum to drum. The spring mounts line up perfectly and
the overall width is within 1" of the original rearend. Its bolted in today.
I have a few things to work out before its finished.
1. The rearend is tilted back and not perpendicular to the ground. Do I need
wedges between the springs and mounts? Or do I have something in wrong?
2. It looks like the shock mounts on the axle will not line up with the mounts on
the frame. What kind of workarounds can anyone suggest?
3. I haven't given much thought to the emergency brake cables. Should I try to use
the 51 cables or the 71 ?
If anyone can help me with these problems, Thank you. This is my first project.

Subject: 6v 12v neg/pos

I'll try one more time,
"They changed to a 6 v negative ground system in 55 (54 and earlier were 6
V positive ground), then in 56 went to a 12 V neg ground system that is
still in use today." 8 )
And my 8N which I have been my workhorse for over 20 years now got a 12
volt alternator about 6 years ago. Much nicer and more reliable than the
old 3 brush generator and 6 v battery.
