If the Balance job has been done right the 250/292s will rev Over that 7000 rpm mark. I have buzzed my 250 to 8000 many times.and Have heard of others buzzing to 10,000 Not that i would want to psh the 10,000 rpm mark But 8000 isn't a problem. My 250 wouldn't think twice at hitting the 8000. But when i built it I made sure that at 8000 the valves wouldn't be floating.
God doesn't like ugly.
