HiYa Steve-
Chances are your flywheel has been serviced before and you simply have whatever aftermarket supplier was there at the time. FORD always had at least two suppliers to supply parts. I can't explain why a 20# diff between the two but suspect one is wrong. Measure the O/A thickness of the flywheel with your calipers or a mic and compare. I machined thousands of FORD 6375 Flywheels in my years as an NC Turning Specialist. I have the original blueprints for them and the ring-gears. EI data has weight of finished parts as well as material specs and more.
