As long as it has enough spring, with the cam you have......... I’m sure the motor would feel like it’s pulling fine to 7500 or so.
That is true. It might not be making a lot of power but an engine like that will just sing for as long as you hold the pedal down. I've done that with a few engines where it just sings in the lights and I think I'm going fast but then when you look at the data you see that you aren't. Once the engine leans over there isn't much point in continuing to whip it even if it sounds good.
