Are 340’s rare

Thank you for the words of wisdom.
I've had three cams in my engine and can tell you that your notion of rpm being a streeter's utopia is fullofchit.
For every minute of rpm a street engine sees on the rev-limiter, in second gear, it will likely spend many, many hours at under 4000 rpm. and if the Bottom end sucks for lack of cylinder pressure, well, that is your fantasy.

Thanks for the timely response. It’s clear you are not an engine builder or tuner. Limited skills make it hard for you to grasp that you can’t do certain things.
