Subject: F350 Front Diff Limited Slip

Howdy All!

Someone made a reference to an item that I've been curious about for some
time -- namely that when you order the limited slip option on the F350,
you get both a front & rear limited slip.

I've got a 97 F350 4x4 Crew Cab PowerStroke (5-speed w/manual hubs & 3.55
gears), and I'd love to be able to verify whether or not my stout Dana 60
has a limited slip in it. Anyone know how to check/verify it?

Thanx & Best Regards,
Jay

Yeah, you're right. If you do the math:

Stroke = 3"
Bore = 4"

Displacement = 3.14159 * 4 in^2 * 3 in * 8 cyl = 301.59 in^3

or rounding up, 302 cubic inches.

and in cubic centimeters, where 1 in^3 = 2.54^3 cc:

Displacement = 301.59 in^3 * 16.39 cc / in^3 = 4942 cc, or 4.942 L.

So it looks like if you round to the tenths, it's a 4.9L!

And if a six is 290 cubic inches, then it's a 4.75L => 4.8L. Don't they
call this a 4.9?

And the 351 is 5.75L => 5.8L.

I've got some serious Ford engine questions to post, but I don't have
time for them now. Stay tuned.

Hello

I have a 97 F250HD truck, and for some reason, any trailer that I hook
ino the trucks factory trailer wiring will not allow for the parking
lights on the trailer to work, and I was wondering if someone out
there had some ideas on what I could check.

Subject: Re: Axle Ratios

In addition to what Dave said, the number tells other things.
Depending upon your engine, the axle ratio can be changed to a
limited slip. Sometimes that changes the ratios, and sometimes it
doesn't. I:n my case, for example, I have a regular cab, 4x2 Ranger
with a 4.0L and a 5 speed. The standard ratio is a 3.08 and I
upgraded it to a 3.55 with limited slip. The 3.08 gears would be a
little better for gas mileage, but the 3.55's get me off the line
quicker. For example at 60 mph with 3.08 gears, I may run 1800 rpms,
but with 3.55's I may run 2100 rpms. (These are just guesses, non
educated) There is a difference in rpms, so the 3.55's at higher
rpms would give less mileage.

Isn't it really a 4.95L, which rounds to 5.0? Nobody is perfect.

The 6 is a 300 cid 6. I think this is really 4.9L.

You may be right. Wasn't there are 290 six in the Ford lineup at one
time? Maybe I'm thinking of some other manufacturer.

And, yes, this would be 4.9L.

Subject: Popping sounds

I have a 1994 F150 4x4 which for about the last 6 months has been making
loud popping sounds (usually several in succession: pop, pop, pop) in
the frontend when I make turns, turn the steering wheel when parked, or
occasionally when I hit a bump. For some reason it doesn't do it every
time I drive it, some days it doesn't do it at all, other days it will
do it constantly. It is really frustrating me, but my warranty expired
in July and being on a really tight budget, I can't afford to take it to
a mechanic if it isn't a serious problem. Does anyone have any idea
what could be causing this?

Thanks in advance,
Eric

Subject: Re: K&N HP or Mileage? and displacement

But, if you use the factory tolerance limits for bore & stroke (at the
high end), and go through the calculation, it DOES come out to 5.0L when
you round it off. On the other hand, who cares?

From: "Shawn & Jennifer Clark"
Subject: Re: K&N HP or Mileage?

Hi-

I've got two K&N cone filters which replaced stock airboxes, both on
4-cylinder cars. One is on a MAF type system Nissan, the other a "speed
density" Honda system. The Nissan has been on for 2-1/2 years, the Honda
for 1+. They both made a huge difference in performance (0.5 seconds 0-60
improvement back-to-back on the Nissan vs. clean stock filter, and 0.4
seconds on the Honda--yes, I measured both with a stopwatch.) I am getting
ready to order a drop in K&N for the 302 F-150 I recently acquired. I
don't expect as much improvement as I received in the other two cars
because of differences in the intake configuration. However, I do expect
maybe 0.2 or 0.3 tenths. Laugh about the comparisons to 4-cylinders if you
want, but that slightly modified 2.4L Nissan makes almost as much power as
the 302--although if falls quite a bit short in torque (only about 185
ft-lb 4500.) Neither car lost any mileage, the Nissan's mileage actually
showed a slight improvement but I considered it statistically
insignificant.

The logic is straightforward, the aftermarket filters allow a considerable
reduction in pressure drop which translates into a small improvement in air
flow--this is not a linear relationship. In part throttle situations the
throttle is controlling the air flow, not the filter so your mileage should
be about the same. At large throttle openings the filter and other
obstructions limit air intake; the K&N allows a slightly denser air charge
to reach the throttle and throttle chamber which means you get more air and
fuel into the cylinder. This will give you more power. Now, if you drive
it around WOT all the time you should expect a mileage hit, otherwise I
doubt you will be able to *reliably* measure it. Depending on the engine
set up the filter may not provide much of an improvement or it may be more
noticeable.

So why don't manufacturers use less restrictive filters and intakes? I'm
not entirely sure, but suspect two reasons: 1. The K&N's increased
induction noise in both of my cars--I attribute much of this to the removal
of the air box and resonators but the filter itself muffles noise.
Non-performance types would definitely find the Honda sound objectionable,
while the Nissan acquired a nice mellow growl when the throttle opens. 2.
According to some data I have seen, the K&N's are likely to pass more very
fine particulates. However, both of my engines are still very strong and
have never used a drop of oil (the Nissan spends a lot of time between
4500-6500 rpm and has 85K on it.)

That is my experience, but I don't know how the Ford will respond to merely
a drop-in filter. As always, YMMV.

Best regards,

Shawn Clark

Subject: 302 again

What I want as far as more power is more speed and take off. So I can
blow away some people around here. So far I really has raced someone
but I beet a 1977 350 Monte Carlo. Besides blowing people away I like
to have power on demand for short distance passing and also its just the
way I like to drive. Fast, not dangerous. Also I am one of those more
power the better guys, it can go to far though.
My 289 Mustang meets this almost perfectly. Still needs a couple
upgrades down the road.

First off, I'm NOT a mechanical engineer (nor an english teacher), but I
think that one of the main bi-products of the internal combustion engine
is carbon monoxide (not carbon dioxide, which other than asphixiation, is
relatively harmless). CO, on the other hand is poisonous to humans and bad
for the environment. This is one of the reasons that the calalyst (some
form of paladium if I remember right), that is used in the catalytic
converters that have been mandated on vehicles, chemically reacts the CO to
into much less harmful H2O and CO2.

The CO2 you could concievably smell as a sweetish kind of smell under the
right conditions, but the H20 just drips of the tailpipe. So, all cars and
trucks that have catalytic converters will drip some amount of water from
the tailpipe, I guess more so the newer the cars, since the emissions have
been getting tighter steadily (my '97 Ranger has two converters one right
after another). As the exhaust system heats up, the catalyst must be very
hot to start the reaction, the water evaporates before it is exhausted.

Since my Physics professor was a gear head and used the gasoline engine as
an example, I hope that I have recalled the "differential heat engine"
principle properly.

Does it sound like the window is going to pop or the glass will crack? My
'84 Ranger has chrome trim around the front windshield, and I THINK it makes
a popping sound. I mean, something pops, and it is the only thing I can
guess is doing it. It does it when it gets twisted a little or when
temperature affects, or just whenever it wants to. If you have that trim,
it may be the cause.
