To use the stock mechanical clutch linkage when swapping in a Gen III/IV engine means placing the new engine in the correct position in relation to the bellhousing mounting face. To ensure accurate engine location, Scoggin-Dickey makes the Gen III/IV custom engine mounts shown here on an iron 6.0L block. |  After we removed the machining...  After we removed the machining block provision, the Scoggin-Dickey clutch linkage ball adapter still hit the outside edge of the Keisler bellhousing, which will require minor filing and a thin AN washer under the adapter to compensate for the Keisler spot facing. This positioned everything properly using the two lower bolt holes on the driver side of the bellhousing. |  Adapting an early manual transmission...  Adapting an early manual transmission using a Gen I-style pressure plate on a Gen III/IV flywheel places the clutch hub too far forward on the input shaft. In certain situations, this could lead to only half the disc hub engaged on the input shaft -which is not good. By using the McLeod 0.400-inch-taller flywheel, the clutch disc hub is positioned farther back on the input shaft splines. |
