Hi Monty,
I am looking to purchase another motor for my 8T 2.0. I have been running an OS Speed and doesn't seem to be enough in the basement for my track. Several guys are running the O.S. 28xz and seem happy, but seems to be overkill to me. I am a v-spec guy and have been running them for the last few years, but have been looking across the border at other brands. The race tracks I attend are around 6000ft elevation. In your vast experience, what mill would you recommend?
