SAAC Forum

This thread is query concerning 'Evans waterless coolant'.
Evans NPG coolant (non-aqueous propylene glycol) and its employment is not rocket science, but it operates on completely different physics laws than water or ethlyene glycol and related additives. It can be easily understood by one simple reading.
Because it is neither water, ethelyne glycol (and related enhancers) based, most of the conventional 'wisdom' regarding OEM cooling system hardware, cooling and media behavior is nonsensical in relation to the OP's question.
Without knowing what it is, good-bad-or indifferent, we end up with a conflated attestation thread like this!

Seem strait cut in this period pic.

Hmm,  the ‘this one is rare’ game.
Aren’t the front mounted battery 1965 GT-350s factually the ‘rare’ ones?
Just going off of the production numbers....silly me!

Very cool pic of Ak Miller (center in dark blazer).

As I recall the Ford Custom Caravan of Cars started off early 60s w customs, but by 1964 was centered more around Ak And the Total Performance theme.
On that rig w the Cobra are:
-a Jeffries custom Falcon;
-a Winfield Econoline;
-an Alexander Bros Galaxie custom; and
-an awesome R code 64 Galaxie (note L/W grille).

A little laborious, for 65s (which isn’t what you asked about  ) the registry lists this info by car. The numbers all all over the place! An SFM car can be turned out on the same day as another SFM number over 100 VINs apart. Perhaps by 67 or the  66 Hertz cars it was a more rational operation (?) haven’t dug that far, but the data is there in the registry.

 
FWIW: 'Police Interceptor' is one of a few terms Ford has used for police vehicles. 'Interceptors' have, as mentioned, been full sized, both 2 and 4 door (historically a great source of wheels for those trying to synthesize SAI history).
The fox body 'Special Service Package' Mustangs are  still popular at the strip and the first gen 'Special Purpose' Broncos are collectables.

George through Kieth:
Just cannot thank you both enough for George sharing and Kieth for bringing to us this absolutely essential SAI history. The former (now lost) thread was IMO the biggest singular treasure lost. To whatever degree any parts of it can be reconstituted, and saved, is of incalculable value to our hobby for us and those who follow.
We are almost down to sole-source contacts for this type of original or near-original attributable information.

A most minor vignette on a ‘day-in-the-life‘ at HPM is the transaction regarding the purchase of my car 5S339: The original owner (I am second owner) had a new black 1965 271HP 4sp 2+2 when he drove by HPM on the way home from work and the cars caught his eye. After stopping and 'getting the bug' he returned and traded in his slightly used HIPO 2+2 for a slightly used 'company' GT-350. His dealings were w Lew Spencer directly and the GT-350 was a driver used by his then wife, Faith, who also worked at HPM. Years later I discussed this in detail w Lew. FWIW Lew & Faith in the HPM days lived on Cheviot and Motor.
I never figured to ask Bill, the original owner, why he just didn't have his car updated w 'Cobra Kits', et al, by HPM at the time instead. Nobody was buying these as an investment then, in fact Lew commented that they had a hard time moving them.

One other 'super-anal' piece of HPM trivia: 5S339 has one of the near sequential HPM CA license plates NQR 8XX which really helps with the timeline regarding ops at HPM.

At least shortly after the beginning, future R model Mustangs, were preordered, not just pulled from the line. At best it appeared to be then sporadic.
