I was wandering again if anyone feels there is power to be had going to shaft mount rockers. Mine are doing well but I read somewhere in a mag. that they installed shaft mounts and picked up 15+ rwhp. Anyone?
I just want a little more power.

 

yes there is power to be gained... how much? it is different from motor to motor. but the shaft mounted rockers eliminated any flex over the stock valve train. also - they are usually roller tipped, and are a little lighter. all that reduces friction, and when you reduce friction in a motor - you get more power.
