You can see this thermal switch in both articles with the engine with the prototype air cleaner. The Ram Air IV engine in the blue and white car as a hex plug in place of the thermal switch. This engine has something else here. Hard to tell what it is. It is hard to tell from the scan but it appears to have a 1 piece intake manifold. Is it a Ram Air II engine? The engine does not seem to the engine of either GTO used in the Super Stock magazine article.

Matt,
Good start. Now keep going back to the prior two articles of the 1969 GTO Ram Air IV Royal Bobcat vs 1965 GTO 389 Bobcat and Press intro of the 1969 GTO Ram Air IV. There is a two peice intake in those articles. Look at the heater hose brakets for routing (one is on the inner wheel well, the other on the front of the engine). One round port car has a heater hose the other with the braket on the wheel well has a caped water pump out let. One has a pluged hole for the thermal vaccum switch vs temperature sensor and a power brake booster in one and not in the other. Not to mention the spark plug wires. One picture has the WX sticker on the front of the block the other tested it is missing.
Also look at the firewall. Two cars have a vacuum line and check valve going vertical. One you can't find it. Where did the third car Ram Air car come from? As you said probably a 1968 GTO Ram Air II with no vacuum booster for the brakes, no vacuum line on the firewall or infron of the car from intake to carb. Even my black and white slides from the strip you will be able to see the thick booster hose just off screen and a thin vacuum line for the front bottom of the air cleaner from the intake leaning on the fron tof the carb. No vacuum lines can be seen on what we think is the 1968 Ram Air II.
Remember the two comparison magazine tests had been done on the same cold day. Just look at the black and white slides from the drag strip I also provided. Some one screwed things up by throwing in a RAII. But it they were still expecting the big air cleaner for the Ram Air IV that never happened. It was just to cover their asses when and if it came. The big air cleaner stayed with the Lime light green/Judge from press Ram Air IV to Judge Ram Air III and did not go on the Crystal Turquoise Ram Air IV Bobcat. The angle of the engine compartment printed in the RAIV vs RAIII is such you can not see the center exhaust round ports like the picture of the passenger side in the introduction of 1969 GTO Lime light green Ram Air IV. Here you can also see what looks like the proper Ram Air IV intake and thermal vaccum switch.
And you think you can believe every thing you read! LOL Things are not always what they seem, are they? LOL
