My '71 F100 w/FE390 and T-18 has a 3.50:1 rear axle.
I like it O.K, but if I get a chance I'm going to change it to 3.0:1.
I'd like my freeway RPMs to be a bit lower in hopes of a bit more gas
mileage. Last year I had access to one of those "dragstrip dyno" programs
for a while and I entered all the particulars for my truck and started
fooling around a bit. Much to my surprise, it indicated that the
best 1/4 mile E.T.'s were to be had with about a 2.80:1 gearset!
Part of the improvement was from less wheelspin on launch, and part
from being able to run to a higher MPH in second and third gear.
The very best indicated times were with about a 3.0:1 gearset and 450
lbs of extra weight on the rear wheels...
(FWIW, I weighed my truck last year, totally empty with about 5 gals
of gas and got a total weight of 3980lbs, with 2360lbs on the front
and 1620lbs on the rear.)
I take the numbers from these "dyno" programs with a grain of salt,
but they are probably at least in the ball park.
IMHO 3.0 gears are probably about the best for a combination of
street/strip in a F100 with 390 and the nasty wide T-18 ratios, but
the 3.50 gearset isn't too bad.
It also depends on what tire diameter You run. Mine are about 29.5"...

I'd like to play with knock sensors, they seem rather interesting.
From my understanding, one of the big problems is that knock sensors
are "tuned" to work with a particular engine. The frequency of the
"knock" sounds are apparently related to bore diameter and combustion
temps and some other voodoo and are specific to a particular engine.
At higher RPM's it becomes difficult to distinguish the sound of knocking
from valve train and general engine noise, and the OEM's go to great lengths
to place the sensor in a good location and use some pretty fancy electronics
to filter out the non-knock noises. A lot of it is now done by processor
to get it all figured out. This subject comes up pretty often on the
DIY-EFI list, and there's been a hell of a lot of good info about knock
sensors over the last year. It seems like knock sensors are a good
thing to help with ign timing management, but unless You've got a big
budget to spend on test equipment and development time it's probably
a pretty tall order to come up with a working system on an engine that
wasn't equipted with one stock...
Still, I would like to get a few sensors from the wrecking yard and play
with them on the 'scope, if for no other reason than the educational value.
I know there's at least a couple other DIY-EFI people on this list, can
anyone else add some comments/corrections/enlightenment about knock sensors?
They seem like a cool thing if we could get 'em to work right on an FE! (-:

Can someone decode the vin for me? It looks like the 240/300 only with
the intake/exhaust on the driver side of the engine.

Where do you think I got the gif from in the first place. One of the
other list members should recognize it from their site.

When I fix it up for now I am going to use the truck at my wife's uncle's
farm. I need to get the feel for it first. I have never owned a truck
that big so I am not sure what other things can be done with it. The main
reason I am buying it is the price. The seller wanted $800.00 at first. I
was the only one who inquired about it so he cut it to $400.00. He just
wanted to get rid of it so he cut it more to $250.00. I just had to have
it then. I love a bargain.

Man, you want some wide wheels! How wide did they come? The wheels
Don's getting from me are 16.5 X 8.25. There called "FanJet Racing Wheel

Ok use locktite on a stud where the dist hold down bolt goes, then use a nylock
lock nut on top of the stud but don't tighten it all the way. next install a
push-pull cable like a choke and voila adjustable timing.

Probably would work best in an all or nothing usage you could vary it but dist
rotation might be hard to control.

Why not just install a 460 and not worry about knock!

My T-18 is dead dog slow to shift, and the ratios pretty well suck.
Granny 1'st is usless, so You've got a 3 speed with ratios something like
3.2:1 2nd, 1.7:1 3rd, and 1:1 4th...
That's a big wide spread btween gears and You gotta make a bundle 'o torque
over a wide range to make it work.
If You want to do any serious strip work You'll probably need to score
a big-block toploader or go with a C6. The T-18 is a great tranny, very
rugged and dependable, but it's a horrible choice for a truck that spends
any serious time at the strip.

Getting a F100 with a 390 to launch hard is gonna be largely a matter
of traction. Move as much weight as possible over the rear axle. Battery,
fuel tank, anything else that ain't nailed down...
I used to run a lot of 1/4 miles back in the late 70's at the now extinct
Baylands raceway in Fremont, Ca., but much of my experiance is with
(don't laugh now) a '67 VW bus (15.83 87mph, 110+mph top speed!)
and Kawasaki 2-strokes(KH500)
Got to ride in a friends 9.2x second AMX a few times also...
God, I miss wednesday and sunday nights at baylands!

If I was serious about 1/4 miling my F100 once in a while, I'd go with
a C6 and start with the 3.5x rear axle, move all the weight I could to
the rear, and do what ever suspension mods it takes to get a pickup to
grab some asphalt...
Go stomp some ch*vy trucks!

Of course I will say more, right now they are on the stock 16.5 x 6.5
No tread in the center tons of tread on the outsides.

I have been told that 16.5 x 9.75 was the widest STOCK Ford wheels. I want to be
able to use the stock hubcaps!

I know Stocton Wheel will widen each stock wheel for about $60.00 plus shipping.
but I would need to buy one more wheel to be able to have this done and still

Subject: Engine ID Tags

According to the Mitchell National Service Data manual, the tag under the
coil is the Engine I.D. It will have a letter on it somewhere that will key
to application and will match the engine I.D. on your data plate. Don't be
surprised at the bum dope at the dealership, they're too busy doing head
gasket jobs on 3.8 Mustangs at $1200 a pop to think about much else.
A question for the four-wheel guys, (sorry for double-dipping here)about my
Dana 24 T-case. The front yoke on the T-case has some side to side (or up
and down if you prefer)play on it. I figured that it needed tightening, but
upon looking at it, I discovered a cotter-pin arrangement. I got the pin out
and tightened the nut with an impact, now I can't get a pin back in. There
are no torque specs for this flange, so I figured that since most go up to
110 to 120 lbs ft the impact was about right. My brother-in-law who is a
really respected mechanic around here says not to be concerned, that the nut
can't back off enough to loose the flange from the yoke anyway, and that the
play I feel is OK. You can still rock it around about the same as before,
does anyone know how much play is acceptable? I have 90wt in it now, but the
Ford manual reccomends 50wt, what do you guys run in it? It is quiet in 2H,
and has what I percieve as the normal straight-cut gear whine in 4H. A
little sweat on it, but no major leaks. Specs on other makes with
sister-cases use 80-90wt.

Hi Jim-

Well, I've seen a few posts giving good advice, so I'll add my 2 cents-
How's your timimg chain? With the water pump off, your about 90% there.
Good time to check it and replace, especially if equipped with original
nylon gear.

Roger, I was looking for the same info about my 1970 Crew Cab. At
my local library, in the reference section, was a book "Standard
Catalog of Light-Duty Trucks". Sorry, I didn't write down the
publisher. This book list a ton of info about trucks produced over
the years, including VIN decoding, options, prices (in 1970, trucks
were generally about $0.75 to $1.00 a pound :-), and production figures.

1970 F-250 production figures are given, along with break-outs for
Styleside / Flairside and other options, but unfortunately for me, no
further breakdown for crew cabs.

I copied only the 1970 Ford section, I see they do give break-outs of
econoline production for that year, perhaps you can find this book....
