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.

I have an '87 BroncoII (2.9LV6) and I don't see a filter on the intake side.
Does anyone know where it is?

Subject: trailer wiring problem

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.

TIA

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.

From: "Eric D. Sipes"
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?
