I also have read all the statements about how ford increased the engine compartment in 71 to fit the 429, but the whole car was increased in size. I beleave the 71 engine compartment was also increased, just to keep it in the proper relationship with the rest of the car?? The 69-70 body was not increased to add the boss 429 engine, just the compartment. Fords statement is sort of like saying that they had to increase the size of the 71 to fit the 429. It was probably just killing two birds with one stone. The 429 fit fine in the other years mentioned. We know that ford plans body styles, 3-4 years before actual production of it. Just look at some of the dates on the factory "clay" photos, which appair in some books. Just my .02
