258 Maximum RPM?

Yes I spent 30min searching, [img]/ubbthreads/images/graemlins/ooo.gif[/img] and nothing, none of my books either. [img]/ubbthreads/images/graemlins/wall.gif[/img]
I know it is relative too. For some reason I thought 3k, but other specs are above 3k.
Thanks.

Re: 258 Maximum RPM?

Don't know the answer, but I have cruised on the Interstate for long distances at between 3000 and 3200 RPM

Re: 258 Maximum RPM?

Definately higher than 3000 rpm. The factory tach has a sort of marking on it, but I'm not sure if that corresponds to a redline (do we define that as a maximum sustained rpm or simply max rpm for any time period?). In my estimation, its a waste to rev a stock motor above around 3800-4000 rpms as it feels like its running out of power above that. No problem revving mine to 3500 rpm for shifts, if a lower gear needed for torque to get it up to speed before shifting into overdrive.
