When did Ford change the size of the flexplate?
When did Ford change the size of the flexplate?
As with the C4, the size of the flexplate generally seemed to follow the size of the car it was used in. Ford changed the imbalance on the 302 (otherwise known as the 5.0L) engines in 1981. Some sources list this change as 1980 in a confusing way, but all of the reliable data I found said 1981 was the first year of the new 50oz imbalance motors.
What does internal balance mean on Ford flexplate?
Internal balance means there is zero imbalance in the flywheel or flexplate, and these should only be used on a custom motor that is internally balanced. Visual comparisons of the 164 and 157 and 148 tooth units should be very obvious as to which is which.
How to figure out what flywheels and flexplates you need?
To figure out what you need, start with your engine and find out what amount of imbalance you need. Then, figure out what size unit you require to match up with your transmission bellhousing. Now you know what flywheel or flexplate you need. Write down exactly what you need, and make sure you get the right unit.

Is the flexplate the same size as the flywheel?
From my research so far, it seems that manual transmission applications (flywheels) and automatic transmission applications (flexplates) generally used the same sized pieces, and they will both be the same size, at least as far as the ring gear goes.
