RPM limiting on a Performance Rebuild...

rockyMember

So I am in the process of breaking in my new motor, 351C bored .030, open chamber heads, hydraulic roller cam, lifter bushings. Duraspark ignition (distributor and module).

I have not taken it above 5000 RPM (yet), but the few times I have let it run, it starts to pull, and shows no sign of wanting to stop revving.

So barring driver discipline, what are the limiting factors on RPM?

Will the motor rev to some natural limit where either the engine's inertia stops further increase in RPM, or valve float occurs, limiting max RPM, or will the motor rev to catestrophic failure?

Is valve float necessarily destructive?

Is there a rev limiting system in either the Duraspark Module or that can be easily retrofit to protect my charging rhino?

Thanks

Rocky
