Maybe you could run an aluminum spool with the 273? Lighten a steel spool and ring gear might be better options. I bought a Mittler Brothers spool with lightening holes in it last year for about $70. They had a sale, so I thought I'd take a chance with them.

I have a lightened spool already, and I am going to dump the mopar SS springs for the calverts.
