The problem is I can't ( or don't want to ) wait for several weeks when everything is apart.
I thought I could take any flywheel from a small block and adopt to the 261 cluth and that was it.
If I use another cluth the arm will not fit the hole, and I need another bellhousing.
I want to make the easiest thing, isn't that to use the 261 clutch and a 283 correct flywheel and if needed have it drilled to fit the clutch ?
But I still need a pilot bushing ?
One of these ?
