List,
All distributors have mechanical advances. Most have vacuum advance, also -
mostly for better fuel economy. Performance distributors only have
mechanical advance (289HP), because those engines don't spend much time just
cruising, where vacuum advancing gives you more total advance; thus, better
fuel economy.
The REAL difference in all these distributors (including Tigers) is the
"curve" that has been set up in that distributor for a particular engine.
There are two criteria: (1) the amount of mechanical advance in degrees
determined by the "slots" in the bottom of the distributor (Ford); and, (2)
the rate of advancement(springs).
To date, I have not found any information that specifically tells me what
the actual "curve" looks like for a given numbered distributor.
I have graphed the "curve" from the Tiger Shop Manual and found it to be
very conservative for both the 260 and 289.
I just recurved a new Pertronics distributor for the "Pay it Forward" car
(Ford 302), and there are a mind-numbing 78 different "curves" that can be
set with this distributor. The Ford is better, though. It has an infinite
number of combinations. Ha.

Kevin,
>From your prefix, C5OF, you may have a HiPo distributor. You need to look
at
the suffix to positively ID it. Attached are some charts that may help.
Remember though, Tigers were not issued with HiPo motors and mechanical
advance distributors. They all had vacuum advance systems. All MK I and MK
Ia Tigers came originally with 260 CID motors and MK II Tigers with 289
motors.
Digging a little further, from Bob Mannel's book on the Mustang &Ford Small
Block V8 1962 - 1969, Appendix D (attached) shows only one "C5OF"
distributor,
a C5OF-12127-E, and it's application is listed for the 289 HiPo motor in the
Fairlane, Torino, Comet/Cyclone, and Mustang. So it appears you have a HiPo
distributor. "Right" for your '65 MK I? That's up to you. Original? No.
A
very cool piece of hardware? Definitely.
My MK I had a HiPo motor when I bought it way back when so I'm not sure what
the correct/original distributor was. I'm sure there are others on the list
who do.
Cheers,
Darrell
