Don't mean to be snide but why on earth would you actually look for
the 28 spline when the 31 is far superior in every way and the track
loc was made for it as well??? Especially if you are getting the
whole rear end? Or are you just looking for the third member? I
have one in good condition with new clutches and 4.11 gears that I'll
never use since the 31's are what I consider absolute minimum now.

This seems to me a good way to do it with large files like the
digests. I usually hit reply and include the whole message and edit
it but with large files this suggestion makes more sense. With
windows I use the shift del and shift ins from the key board and
never have to touch the mouse. All windows programs use this method
for cut and paste. To delete press the shift key and cursor down to
the point you want included, release the shift key and press del and
it's gone, to copy continue holding the shift key and press del and
to put it back (paste) press shift and ins. I love it. Presonally I
think it's a little better that Ctrl K K, Ctrl K C and Ctrl K V to do
the same thing in word star :-)

To those of you who have problems with Holley carburetors, the following is a
copy of correspondence between me and Holley's technical support, and an example
of what you can expect. I think it speaks for itself. You'll notice that my truck
is a 1980 model but has more in common with the 79 and back so that's why I'm on
this list.

- --- Begin Included Message ---

Nothing in the calibration of the carburetor via jets or metering plates
will cure the condition that you have described. The carburetor is just
plain flooding due to high fuel pressure, float levels, blown powervalve or
over torqued powervalve. Debris in the needle and seat as well as blockage
of a bleed or orifice would cause the same thing. Check the floats for
bouyancy. tkyou

Subject: 3160 (0-9834) running rich
Date: Tuesday, September 30, 1997 2:44PM

I installed a new Holley 4160 with part number #0-98934 on a completely
rebuilt 302 in a full-size 1980 Ford Bronco. Idling was a problem and I
found that I have to have the secondary throttle plates completely closed
in order for the engine to have any idle and performance. You (and the
instructions)advised that they should be opened just enough to expose a
fraction of the secondary transfer slots but this carb will not operate
in that position. I have finally gotten a measure of performance (not
what I have had though), but I still cannot keep the carb from running
rich. I have about 11-12" of vacuum at idle in gear. I replaced the 6.5
power valve with a 5 or 5.5 as per your suggestions. I tried smaller main
jets (61 verus the 68 that came installed) and noticed no difference. Of
course I have adjusted float levels, and installed a fuel pressure
regulator to regulate down to 4-5 psi. I have no detectable vacuum leaks,
gaskets are good, and have found no clogged passages. Mileage dropped
from 15 mpg with a Ford 2150 two barrel to a best of 8mpg with the 4160.
I expected better mileage, especially with staying out of the
secondaries. The only thing I haven't tried was replacing the secondary
jetplate with a smaller one as was suggested by a local mechanic. I am
not sure but I believe the stock jetplate is a #9. I don't have the specs
with me. Tailpipes are sooty black and it will spray the cars next to it
with black specks if you rev it at all. What effect would going to a
smaller jet plate have? How much smaller can I go. The truck is just
running (and idling) way too rich.

Thanks for any help! I'm at my wit's end.

According to the '79 Ford Light Truck Manual for the Bronco
and F100 - F350 the Axle code for Limited slips are:

H3 - 3750# 2.75
H2 - 3750# 3.50
H9 - 3750# 4.11
H4 - 3750# 3.25
B4 - 5300# 4.10 Dana
C7 - 5300# 3.54 Dana
C8 - 5300# 3.73 Dana
D7 - 7400# 4.10 Dana

There is also a tag on the axle, if it hasn't been lost or
destroyed. On the Dana axle, it should have a L-S in the
lower right hand corner. For the Ford axle there should be
a letter L in the ratio number in the lower left corner.
The ratio on the Dana is in the upper left corner.

I'm not certain but I've been led to believe that the 31
spline axle is on the locking axles. I don't think you will
find a 28 spline in the limited slip axle.

Keep us posted on what you find.

You may find that you don't have to replace the hubs...the older fords
used a dana/spicer multi piece assembly that is very easy to repair. Its
just not as easy as the new style one piece. The older ones are a much
stronger system though. If you pull the cap off...by removing the allen
screws on the hub you will be able to turn the knob and unlock the hub,
then replace it and you should be back in free wheel...let me know how
ya do..Brian

What they say is basically true. I've had two holley 4160's and they
are definitely not your most economical type but they will definitely
run well and without flooding with the right set up.

Number one, is this the right version for the stock 302? Is your
engine actually stock? If Yes to both then at least one of the
things they told you has to be the culprit. You can only jet down so
far before the engine starts missing at cruise and WOT. If you
haven't reached that point yet maybe you do need to go down some more
but it's unlikely jets would cause that much richness unless they
were way off.

There is another possible culprit and I have personal experience with
this one. My intake manifold was not properly installed and the carb
does not sit flat on the mount so I had to loosen two nuts to relieve
the twist in the housing to get the secondarys to go completely home
so it would idle. This twisting can also unseat some stuff and one
place I don't think they mentioned was the check ball in the
accellerator pump. I got it in the wrong hole once and it flooded
but mine wouldn't run very well at all like that so maybe thats not
it. Over torquing the power valve will unseat the valve allowing it
to leak all the time.

On the secondaries, the slightly open at idle thing is for built
engines that require high rpm idles and relieves the primary throttle
plate a bit so it DOESN'T go past the transition slot which causes an
over rich idle :-)

I don't have my catalog with me so can't look it up, you didn't say
what the CFM was?

I don't know how to tell a 31 spline from a 28 spline without pulling
an axle, but You've got my curiosity up... Is there some reason why
You need a 28 spline axle, and cant "settle" for a 31-spline?

Subject: Re: Holley Rant

Here's the deal. All that Holley mentioned, I had already tried or checked out.
I had put in a pressure regulator (with a guage), so pressure wasn't the problem.
Set float levels (new carb, so new floats)..not the problem.
New lower rated power valve. By the way, I'm sure it's not overtight, but how could
that cause any binding? The way they're made it doesn't look like it would be
a problem. I took it off and blew all passages, and installed a really good inline
filter..so trash isn't the problem. They say it's "just plain flooding".
True. It's really running rich at idle. It seems to run okay at cruise, but
main jet size doesn't affect idle. Something I read in a Holley aftermarket book
suggests placing a small wire in the idle circuit to reduce fuel flow. Holley
doesn't mention this and I'm wondering how large a wire would do it, and more
importantly, why would you have to? The book suggests to do this instead of
enlarging the air bleed size because doing that would really affect too many
other things. The carb is a 600 cfm 4160 (vacuum secondaries) # 0-9834, which
is a general replacement carb that comes with a #64 main jets (I believe I
remember correctly). The 302 is basically stock with a MILD RV camshaft.
So, Gary (or anybody else), got any ideas?

I'm not familiar with all the tag codes and don't have any books on
it yet but with a 2.75 gearing I would bet you already have this.

The problem is that the 302 doesn't have enough torque to support
wide ratios in a heavy vehicle and really needs an over drive. The
AOD would be a good transplant and would keep your top end close to
what you have now with the 3.5 gearing (let me go visit my spread
sheet, just a moment) I'm back, the 2.75 at 60 mph with 29" tires is
1912 rpm. With 3.50's you would be running 2434 with the
present setup and with a 25% overdrive it would be 1826 so with an
over drive you could go even lower and still get good economy but
would pull much better in the lower gears and it would give you one
more gear which the 302 really needs IMHO :-)

I don't know off hand what the overdrive actually is but most I've
seen listed seem to be around .8 in which case 3.86 would net you
2145 at 60 with 29" tires but would give you some nice torque in the
lower gears. 3.55 would give you 1975 which is a slight improvement
over your current condition in top gear but would give you more
options in the lower gears. The GT mustangs ran 2000 rpm or so in
top gear but they had Hypo engines and light vehicle weight and
weren't designed to tow but they got good mileage at that rpm.
