Do you have a minimum bob weight you need to have?

Thanks for joining the forum!
my bore is 4.733 and my stroke is 3.55. I would like to try a 4.75 bore combo but my budget just isn't going let me.i think alot of teams run 4.75 bore motors.
I run steel rods so we aren't close to the min. Bob wt rule.

I'm a little shocked that you run steel rods...I would have thought aluminum would have free'd up a little hp...is this more of a longevity issue?
