That's what I mean - the engine is not designed/balanced to turn 9,000 rpm. It probably wouldn't be pretty,
especially if it was for any extended amount of time.
To make use of 9,000 RPM on our engines, the cams and valvetrain would have to be re-designed and the whole thing would require balancing and possibly better hardware, hardened parts, etc.
Believe it or not though, a v6 is usually smoother than an inline 4 (from what I've experienced at least).
High N/A power on these cars is probably going to be like most other push rod cars - rough idle and not very street friendly.
