OE Style Replacement 157-Tooth Flywheel for 1981 and Older 289/302

Flywheel, Cast Iron, 157-tooth, External, 28 oz. Imbalance, 10.5 in. Stock Style Clutch, Ford, 289, 302

• Balance Differences: 289 (all years) and early 302s (1968–1980) use 28-oz, while 1982-up 302s (including 5.0L) use 50-oz.
• Tooth Count/Bellhousing: Both engines commonly use 157-tooth or 164-tooth flywheels, which must match the bellhousing, starter, and clutch size (e.g., 10-inch or 11-inch).
• Compatibility: A pre-1981 302 flywheel will work on a 289. A 1982-later 302 flywheel will not work on a 289.
