I'm getting a cyclical vibration from probably 1500 to almost 3000 rpm, most noticable around 2200. It's motor-based, not center bearing/guibo/whatever, cuz it'll do it sitting at a stop sign in neutral, clutch in, it'll vibrate/resonate.
The water pump has bad bearings, the fan has a lot of wobble, so I'm changing that this weekend, along with a new radiator (old one's leaking)... could that be causing my problem? I also have heard this vibration is normal (poor V8 balance), and bad motor mounts can exaggerate the symptoms, and I know my mounts are shot (if I rev it in neutral, it REALLY rocks back and forth.
Any other ideas?
