Tom, on the 292 thread you mention that you're pushing the 292 to 5400 RPM and that's into the concern range.
Of course with all the problems and crap with my 250 I'm not sure what to believe but the guy I bought it from said that the builder said his engines (built for the Nascar dirt track series in VA) would turn 6000 all day.
I doubt that my engine will ever see close to 5000 but just wondering...given the shorter stroke, what is the RPM range for a flat top alum piston, small block rods, balanced 250?
