Ford 8" and 9" Diffs what horsepower will they handle ?
Been a lot of talk in different areas about how much horsepower these diffs will handle. The 8" is a lighter duty than the 9" but works well under a light and medium weight car. True ?
The 9" seems to have a big difference in various setups like grey cast iron, nodular, open, positraction, locker. Then there are spline sizes like 28, 31, 35 and 40 spline with numerous different carrier bearing sizes. Where does a guy start ? And what kind of car/racing exactly demands "heavy duty" ?
So everybody that runs them must have a different opinion of them.

The first model car I built was a 32 Ford roadster by Revell in the mid 50's.
