This bellhousing that will allow you to bolt a 3, 4, or 5 speed transmission to the 1957 thru 1966 Buick nailhead engine. Some 5 speed transmissions will require a second adapter plate.
We make these here in the U.S. They are cast and machined in Minnesota. This part is NOT meant to be an exact replacement for the stock Buick bellhousing. We have flywheels available for these engines as well.
This bellhousing does NOT fit the 264 / 322 nailhead engines.
