Yup - what Jerry said. It's too big. You could use a Mallory Unilite which is a solid state system (no points) https://www.summitracing.com/parts/m...kaAkGQEALw_wcB
with a remote coil such as a Mallory Promaster Classic https://www.summitracing.com/parts/m...oaAlonEALw_wcB
Bear in mind that the two Mallory components would add another $450-500.
Note the distributor on this BBC with tunnel ram..
