Well can you explain the airfilter assembly and throttle controller in the picture then? How do you know for sure that's when they started the idea, I don't know how someone can just say NO. I'm sure we didn't think the mustang was being developed in 1970. Unless the date of this picture is incorrect, I did get it off ODK.

So many times I hear that info from this era isn't very reliable. Just because you believe something to be a certain way for a long time doesn't mean that your information is correct. Just look at the serial number information all saying that the 73-74 engines were 77 and "WE" proved that the formula being used was wrong.
