Looking at a nice 69 Mach 1 Q code. Now I think I know the difference between the R code and the Q code. I believe that it is within the motor! but I wanted to find out for sure.
Anyone know anything about production numbers on these?

Both are factory 428 cobra jets, the Q code just doesnt have the Ram Air assembly known as the "SHAKER" which protrudes through the hood. The Q code has a fake air scoop mounted on the hood. the distinct sound made by the shaker is what sets these bad boys apart.
I found where there were 13, 193 Cobra Jets manufactured in that year, but can't find a break-down of how many Q's and how many R's there were. And, all the sites I found stated they both had the same exact horsepower.
