Where do you plug in reverse lights on a FMX transmission. The tranny is
from a 76 Torino and it is in a 78 F-150 Ranger.

My FMX is in a '67 and it has no wires to it whatsoever. The backup light=

switch for mine is integral with the neutral safety switch near the base =
of
the steering column, on the inside of the truck, down by the firewall.

Hope this helps,

Tom and other friends, I believe I'm finally on to something with
this timing thing and I'm really excited! :-) We've been discussing
this for some time and it occured to me that there are several things
that didn't get completely worked out but which I think I understand
now:

The 10 - 12 initial and 34 - 38 total with no vac it strictly a
performance street or racing thing and requires a non stock
distributor since stock distributors don't have enough range to get
it done without modifications. Ford Dura Sparks have anywhere from
13 to 21 degrees in the mechanical advance and with even 12 degrees
initial it still only gives you 33 degrees total and most of you do
not have the 21 degree version. The rotor has two settings built
into it and by rotating it on the stop 180 you can get the other
setting. This requires removal of the pickup plate, felt pad, snap
ring and springs (carefully). The range is stamped into the arm on
the rotor near the slot the stop runs in. We build them here and
I've looked for the highest range and found 21 to he the highest
AFAIK.

Idle only needs to keep the engine running so timing isn't critical
here and is not part of the equation so initial can be what ever you
need to make the rest of the range work. Obviously, moving the
initial without changing the mechanical curve will also move the
advance at any given rpm by the same amount which must be taken into
account.

The vac will probably fully retard no matter where the spring is
adjusted at WOT so the initial timing is what causes spark knock, not
the vac.

The additional, seemingly excessive advance offered by the vac is
only partially used except at idle and decelleration so the spring
pressure determines the advance you will have at any given rpm and
vacuum value (throttle position) so an adjustable stop is not
necessary.

To obtain best economy and still have full performance a vac is
necessary since at cruise and part throttle the volumetric efficiency
is lower and mixture is leaner so more advance is required, lots
more.

Here's what I've done so far if anyone cares:

Initially I set the timing at 10 degrees but then discovered the vac
wasn't working so I oiled it and freed it up and replaced the hoses.
It was hooked to manifold, I don't think I have ported on this carb
so I haven't tried it yet. After fixing all this and resetting to 10
degrees the spark knock was gone under normal operating conditions
and it ran pretty well.

Moved initial to 12 since every one said that's the thing to do to
get more power and..............

Spark knock came back, found pickup plate bearings hanging again and
re-oiled, checked mechanical and all was well but now it's knocking
at low speeds and moderate throttle as well as at WOT.

Reduced initial to 10 degrees and knock is better but still at low
speeds and WOT it's bad.

Crank in the vac three turns, still at 10 degrees and "seems" better
but still there at WOT but now I have sluggish response at cruise and
seems to need more pedal to hold 60.

Back it out 4 turns (1 turn out from original setting) and knock
doesn't seem to change much but now my response is back to normal at
cruise and maybe just a tad better but have surge at 35 mph in high
or near idle in third which I never noticed before.

This morning I got up early so I could fool with it a bit and reset
the initial to about 8 (didn't have time to mark the damper) and
backed the vac out one more turn. Low speed surge seems to be gone,
can't detect any serious spark knock under any conditions, vacuum is
essetially the same (15") on level roads at cruise (60) and throttle
response in cruise range is very good and requires very little pedal
to maintain 60 so I expect economy to improve if only marginally.

What I get from all of this is:

1..Initial timing is the spark knock culprit in most cases

2..factory curve is adequate for most applications except HIGH
performance and racing when initial is properly set.

3..Vac is necessary for best street performance and economy and can
be used to shift the cruise advance up or down with spring pressure.

4..Cruise and part throttle (light throttle) requires MUCH more
advance than most of us would suspect for proper operation due to
poor volumetric efficeincy and lean mixture, as high as 45 or 50
degrees possibly which is the job of the vac.

I'm wearing my flame retardant suit today so flame away :-)

Axle grease? From the rear end? Better check the axle seals. This
is a full floating axle so I don't know if the diff lube can get in
the brakes or not but better check it out :-)

I'm subscribed to two list because they both have info I can use and
I can share my experiences with an enthusiastic audience as well. If
the old truck list is split into old and older lists I can still
subscribe to both if I want and each reply will only go to the one it
came from so I can still have all the info if I want but the guy who
has limited time to browse the mail will appreciate a smaller, more
pertainent list so we both win. I don't see what all the fuss is
about, just pick a good spot and cut it, the rest of us will
resubscribe to the older list or visa vera if we want, right???

I agree. I don't have an early truck now, but when my dad had trucks in the
late 40s and 50s, I worked on them. I still have service manuals (no they
are not for sale) from them and I have posted replys to questions asked
about early trucks. I like them, but I won't really have a reason to read a
split list. maybe my .02 worth of advice aint worth much, but it will be
lost to those not on "my" list.

It actually makes more sense, but the term "List Mom" has long
been used with mailing lists. It refers to "Den Mothers" of
Cub Scout troops who have to manage 500 screaming kids at once
without losing their cool.
