Hi,I have a '73 GMC with an unmodified Olds 455 in it. Does anyone know at what RPM this engine reaches its maximum torque?

Also, does anyone know what the engine's "redline" (maximum RPM the engine can safely reach) is?

At least on my engine, it kind of seems right now that the engine torque curve drops off fairly significantly so that reaching "redline" is pretty hard. However, I'm not sure.
Any information would be appreciated!
Thanks,
Keith Lee (SF, CA)
