427SSS.....
I believe your pictures originated from the from Motor Trend 9/63 (hows the memory??) I didn't go look. This was during the early months when Shelby was spinning his web and attempting to gain exposure for the car. Some of the earliest cars were painted numerous times and given to the press to garner their comments and creat the illusion that production had been ramped up and that many cars were available.
The engine shows some items that were unique to this photo shoot and to the to the Hipo theme and subsequent production.
These pictures were taken during a road test that was done at Riverside Raceway. Car was red with black top, narrow wire wire wheels. This particular road test/article had an imense amount of information in it. If you are a small block fan check it out.
Questionable if this was really a 289 although print indicated it was, any information to the contrary is welcome.
The 260 engined cars all had the
oil filler through a passage in the front timing cover with a single filler cap.
No vents in the hollow letter rocker covers. Rare (unique to 260 cars?) Note there is no pvc valve or smog control of any type on this, as it was prior to them being put on any vehicle.
Vacuum pot on the distributor...never part of production 289 Hipo
parts this is the only picture of one I have seen.
Fuel filter attached similar to FE motor. Prior to being made part of the pump itself?
The Harrison sourced tank is attached above the LH manifold, was later replaced by a smooth top tank similar to that of an FE mounted also above the LH exaust manifold.
No side vents as they were later added as prodution items to solve complaints of heat from the V8.
Generator instead of 45 amp alternator.
Any additions/corrections welcomed.
