Or would a 1964 283 flywheel work with the 305? | | | | | Joined: Jun 2004 Posts: 8,597 Riding in the Passing Lane | | Riding in the Passing Lane Joined: Jun 2004 Posts: 8,597 | 86 was a transition year. If it has a 1 piece rear main seal, the 87 will fit. If it has the older 2 piece seal then the 64 will work. . I am confused on the flexplate/manual 4 speed thing. Check the flexplate to make sure it has bolt holes to the converter. There are some variations in those. They say money can't buy happiness. It can buy old Chevy trucks though.
