1970 original 440-6 (yes the bubble is mounted to the hood)

While all the experts are here on the subject, here is a pic of my bubble. I didn't actually get the bubble out, this pic is old, but it sure looks like it has 4 holes. Is there any logical reason why someone would have added a 4th hole in-line with the emblem holes?

I guess the Challenger emblem should read "383 Four Barrel" for a 71 R/T shaker? And equally should use a 3-pin emblem?

Thanks!

Paul,
Parts manual information sometimes differs from what was actually used in production, the reasons vary but usually last minute changes or mistakes had occured that didn't make it into the manual before it was printed, likely the scenario in this case.

Ludington,
hard to say but originals only had 3 holes, it's likely someone added a custom/non stock emblem in the past that required an extra hole, tough to guess on that one.

Interesting observation and picture, but could one possibly also interpret that to mean nameplate for the scoop on the hood of a steel hood. I assume those are the nameplates that came with that packaging.
The photo Jules submitted is a true 440-6 shaker 3 prong nameplate and the box with it has 3462273, a part number number that is found in an earlier printing of the 71 parts books indicating shaker scoop nameplate.
Parts books printings were updated along the way through the model year to correct or update.
I notice yours is a Dec 1971 printing, the final printing and there are two asteriks beside the part number 2998798 which the key states "indicates change or addition".
Another oddity in the same column is "340 four barrel" obviously a Challenger emblem in the Cuda section.

It's official-I give up on E bodies, I'm going back to B bodies where I belong No really the more I learn the more I din't understand about these dxxx cars. After 20 years it's amazing what one can still learn, but fun nonetheless!

Dont give up that easy. These cars all baffle us when we find things that arent supposed to be. Who's to really say for certain.
Just for the heck of it here's a page in the 23 section of another Dec 1971 printing showing the shaker nameplates for 1971 Cuda ( top left of photo)

same parts book showing shaker nameplates for 1970 Cuda, top columns....the two prong steel hood nameplates below that

A photo of the rear of the two pin and three pin 440-6 nameplates.
They were two different castings as seen by the casting number on the rear... 3462273 on the 3 pin... 2998781 on the two pin, same vendor 31025.
