Allright you guys, joke's over
I just tried your theory out on mine ('97 LS 3.1), it will freely rev to 4 grand+ in neutral or park.
You guys must be talking about either:
Older models
3.4 DOHC's or
Manual Transaxle models
I admit it would make sense on an MTX model, to keep you from grenading the motor if you missed a hard throttle upshift. Is that what you're talking about?
Or were you just trying to see if I was dumb enough to go dynamite my motor to find out if you're right?
Good one, guys.
