Just for reference, the company "Fluidampr" makes two differnt diamater dampeners:
http://www.fluidampr.com/FORD.htm, 7.5" and 6.5"
March's fluid dampener comes in only one diameter, I believe it's 6.25".
The stock Ford 4.6 dampeners are just under 7" in diameter and have various weights.
5.8lbs for NPI 2vs
6.5lbs for cobras and marks 8s
8.95lbs for PI 2vs
9.9lbs for marauders, mach 1 automatics and aviators
Note how the cast iron crank 4vs and the PI 2vs have a heavier dampener than the 4v engines with the forged cranks.
