No you can't, but there is a 71mm available that's a true bore but you really don't need anything bigger than a 69mm true bore on the 4.7L as it will feed more than enough air even for a roots type blower. There are ported versions from Fastman, Moes, and Modern Muscle available for the 4.7L ranging from 71mm to 78mm, depending on how/where you measure the bore.
