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.....
