Quick question...
Does your car run as smoothly at high RPMs as it does down low? My car is as smooth as glass below 3500-4000rpm, but up around 5-6+, it's not the same. Since this is my first manual transmission car, I'm curious if this is normal or if it's an indicator of something?
On previous (automatic) vehicles I've driven, yeah sure, they get louder as they rev, but this is more like a "shake." Any thoughts?

I see you live in Milpitas - you mind if we go out on a ride sometime? I'd like to ride in your car and feel what it's like, and then have you ride in mine and compare...

Higher RPM slippage
From what you described it sounds like you may have a clutch thats starting to slip. Usually you will see a worn clutch (friction material) start to slip at higher RPMS first and over more time that slipage will become more noticeable with less and less RPM. Another Couple of things to consider is fuel prerssure/volume. you could have a fuel filter thats plugged or a fuel pump thats on its way out. easily checkable with a fuel pressure tester with a relief valve. Lastly with that kinda RPM depending on the Age of the Vette, your Rev limiter in the PCM (computer) could be kicking in and limiting the amount of RPM's the engine will do. Iam not sure what the rev limiter is set at on Vette;s but on your daily driver 3.1 GM's its set at about 4000 RPM if the PCM doesnt sense a vehicle speed sensor input. Hope that sheds some light.
