Perhaps someone has solved this problem.
I have just melted my second interior dome light lens. I guess this
is because of the heat from the bulb at 12Volts.
Ok, I could build the requlated power supply. But I would prefer
to find a lower wattage bulb.
We are off to Carlilse for the Nationals on Thursday and will
send a note upon our return.
If anyone is going you will find us in Building "T" from early
Friday AM to 10:00 Sunday Morning. My wife, Wanda, and
I will be wearing black baseball jackets with Mass Cruisers on

I have a 60 F-100 that has at some point had it's drive trained swapped
It currently has a 70 something 300 6cyl and automatic transmission, one
ton drive shaft and a 9 inch rear end with 3:23 gears.
I currently have 235x60x15 tires on it and of course my speedometer is WAY
I dont know what type of tranny this is to make a guess at what gear I need
for the speedometer. I assume it is a C4 or C6 but dont know how to
eyeball it to tell the difference.
Will this even make a difference for the gear change for the Speedo?
Also, do I only have to change the gear being driven by the speedo cable?
I am also considering switching to an electric wiper motor (vacuum now) as
provided by Obsolete Ford Parts. Does anyone have any experience with
these motors? Anything to look out for? Anything else that might need to
be replaced along with it?
Any help would be appreciated. With all the rain we are having here lately
I REALLY want to go electric. :)

Subject: 58 F100 front disc brake kit
I'm looking to add front disc brakes to my 58 Ford F100. I read a mag
article some time back about
a package from Engineered Components. Apparently they've been producing
kits for earlier models for
some time, but are just now coming out with a kit for the 58. Does anyone
have any advice for me
or experience with this product, or disc brake conversions in general.

Subject: Flathead V8 dual exhaust
I would like to tap into to the collective wisdom of this fine and
knowledgable group. I have a 1940 pickup that I plan to restore over the
coming years. To date, I have rebuilt the engine (85 hp flathead), brakes,
frontend, etc. It is presently my weekend driver. I have 2500 miles on my
new engine. When I rebuilt it, I upgraded all of the components of the
engine. I have heard that dual exhaust help the performance of an engine. If
so, how much? What modification I make must be reversable. I am not souping
my truck up, I am only interested in improving its performance. When it gets
show ready, then I will put the old system back on for originality. Here are
Are dual exhausts beneficial?
Do I need headers? ( or can I come off of my existing exhaust manifolds?)
Are there any problems associated with such a conversion, such as running an
exhaust line past the steering box and master cylinder on the left side of the
in The Beast

I have a 40 pickup and have a blast driving it around town. I have l long
since gotten used to the fact that Highway driving is out of the question. It
is a 3/4 tonner and the rear end is geared to climb trees not cruise at high
speeds. If you want to keep it original, like I do my truck, then brace
yourself for the original charm of driving a truck of that vintage. Much of
which is slow speeds and a real stiff ride. Since I got my truck I learned
that old men don't drive the way they do because of their age, it's because of
their trucks. If you can get used to the fact that you will be restricted to
around town and vacant back country roads then go for it and have a blast, I
did and I do.

> little formula like this:
(driven gear teeth X axle ratio X tire revolutions/mile) divide by (1000) =
drive gear teeth. With an automatic you can have either 7 or 8 driven gear
teeth, you have to take off the tailshaft housing to tell.
Being lazy, I like this method. Drive 10 miles or so on an Interstate or other
highway with mile markers. Check your odometer as you pass the 1st marker, and
again at 10 miles, write down the results and repeat one or twice. More miles
means less error. say you traveled, by odometer, 12.2 miles.
divide the miles traveled by actual miles (12.2/10) = 1.22. this means your
speedometer is going 1.22 times faster than it should, and you need a gear with
more teeth. (more teeth drive the speedo slower, fewer drive it faster) Pull
the speedometer cable out of the transmission (be ready to catch some oil) and
remove it (the gear) by removing the clip that holds the gear on the cable.
Count the teeth and multiply by 1.22. say you have 18 teeth now, you need
21.96, of course you wont find a gear with 21.96 teeth, but 21 works and will
keep the speedo just optimistic enough to avoid police trouble. Almost all late
('57 up, maybe earlier) Fords use the same style speedometer gear. C-4, C-6
makes no difference, also manuals. The older Ford stick shifts were different.
If you need more than about 22 teeth, I don't think they are available. There
are external gear boxes available for extreme cases, but you probably need only
a 17 or 20 tooth.

Subject: 12 v pos/neg gnd
"My 55 came stock with 6V pos ground :o
Just thought you might be interested."
yes I am interested, however I think you are incorrect. It is still my
belief that all 55 Fords started life with 6 V neg gnd systems. Many were
changed over early in life by mechanics who had no understanding of
electricity, and most did not back then. All that is needed is to put the
battery in backwards (which was the same way they had always installed
them) when installing a new battery, then when it will not charge correctly
they would repolarize the generator (every mechanic new how to do this but
most did not know why they needed to do it) and everything would work
properly. Since they used a light rather than an ammeter there was no way
to tell which it originally was. Unless, that is you are an old coot like
me and remember this stuff, or have a 55 shop manual with that level of
detail. 8 )
Please write back and tell me why you think they had a pos ground.

Subject: Carlisle and Ford 8N
It seems like a slow weekend. First about Carlisle: who is going to
the Carlisle Truck Nationals on the 19, and 20th? I know Howard Tarnoff
and his '55 will be there. I plan on looking him up.
My Dad had a Ford 8N Tractor on the small farm we had. A great little
tractor it was. One time he felt he needed something bigger and traded
it in for a newer (a blue model) and more powerful one. A week later he
went back to the dealer and bought the little Ford back because it was
so valuable around the farm. He finally sold the Ford when he sold the
farm. I don't remember what it sold for but some guy from New York state
bought it (we lived in Southern PA).
I still enjoy looking at these neat Ford's as I drive the roads of
rural PA as I keep my eyes peeled for F-series Trucks.
Have a good weekend! Abe Stauffer

Subject: Dwell Angle versus Dwell Percentage
I need help!! What is the difference between dwell angle and dwell
percentage? I have my 52 F1-- the dwell gage says that I have about 19
degrees of dwell, however the book (FORD Shop Manual) talks about 58-62%
dwell closure. I cannot find any transformation tables or conversion
factors. What should the dwell meter say? Is my 19 degrees right? The
truck seems to run just fine?!!!!!!! This cannot be complicated, however,
don't have any guidance on this matter.
