That would be the Ford F Series Shop Manual for 1949-50-51-52. This would,
of course, be using a 6 volt system. The diagram doesn't show a resistor
or anything unusual in the circuit.

I'm going on the assumption that the original poster has a 6v coil in the
12v system, with a volt drop wired in. The way he described his points and
plugs sound very "6v ignition" to me. Naturally, if he is going to install
a 12v coil he should use whatever resistor is appropriate--I just am
suspect of the one he has now.

I had this problem in my 73 F250 Highboy. It ended up being the
thermostat. When I installed it it slid down a little bit and to much
coolant was getting past it. Replaced it and the heater gets plenty hot.

Subject: RE: 351M Cam Timing

In Pat Ganahl's book Ford Performance, page 84, there is a mention of For=
d
retarding cams: "One of the first things Ford did to meet smog
restrictions, beginning in '72, was to retard the timing on existing
camshafts." It has a picture of a multi-index crank (yes crank) sprocket.=

It has 6 different keyways in it. =


This is in regard to the Cleveland family of motors. =


Hope this helps,

Not a "wiz", just a devotee.

Speculation:
I don't know too many details about this cam retarding thing. I've been
told by professional mechanics that it is true and I have also read about=

it, so I believe it's true. What I don't know is how much and when. I
vaguely recall reading somewhere (years back) that cams were retarded abo=
ut
2-4 degrees, but can't remember the source or specifics.

Facts:
What I do know about M-block cams is that beginning in 1977, Ford changed=

the cam spec on the truck versions of these engines. Before '77 (and in
car engines through '79), the 351M used a lower lift cam than the 400. I=
n
'77, both engines (used in trucks) were fitted w/ the same cam that gave
0.250 at the lifter (0.433 at the valve) on both intake and exhaust lobes=
=2E
This was more lift than the cam used in car 400s (0.247 intake, 0.250
exhaust).

Yeah, I had forgotten about this one. My Maverick had a big hole in the t=
op
tank of the radiator. Being the cheapskate that I am I just ran with it
(who wants to put money into a 4 door Maverick???). Sure enough, when it
would get to a certain point, it would only blow cold air out of the
heater. =



Steve. I've been running my heater lately. It's all stock and it works
great. 1967 352. It gets to the point where I have to turn it off. Then
again, it hasn't gotten to -20 yet. =


There is something really strange goin' on there....

Good luck

I used WD40 on mine. Hell, I use WD40 for everything. I should probably t=

something else someday...

Sometimes leaves and crap can get down in there and jam up those doors in=

the heater control box. Also, be careful not to break the little clamp
doohicky that clamps the cables down to the control unit and box etc. I
broke one of these once and had to go to 4 different junkyards to get a
decent one. PITA!!!

My '68 has slides. They're quite stiff. Has anyone tried a motorcycle
cable oiler or something? I'm always afraid I'm going to rip the
sliders out of the dash tugging on them.

Even 12 volt systems use a 6 volt resistor for the points it stops them from
burning up so easy.

Is the black coating on the plugs a dry soot black, if so you have a lproblem
with the fuel mixture normally.

If it is a slimy wet black the you have a oil consumption problem.

If you have a 12 volt battery & coil & your points, cond. cap, rotor & wires
are in good condition I would look at one of the above for the problem

It seems what you didn't re-use, somebody heated up and sold for coffee here
in my office!
