340 Vs 360

I can tell you ain’t an engine builder.
Correct, I'm not. Are you?
Any engine builder who has done this for very long will tell you RPM is KING. Because you don’t know it or understand it is a you thing.
I'm not anti-RPM.
RPM is part of what it takes to make horsepower.
The other part is torque.

Neither can be king on their own.
I could put a 1200cc motorcycle engine in my valiant and it might rev to 12,000RPM or beyond

But it'll be slow. Because it won't make the horsepower of a 340 or a 360.

Are we really disagreeing on whether horsepower is the measuring stick for performance?

I posted a link to the 2023 Engine Performance Expo. I doubt many watched it. But it’s free.

I suggest you spend some time looking at the EFI University LS build and then come back and say RPM isn’t KING.
Would love to watch it, is that link somewhere in this thread?
