Engine trouble's Had this posted over in the Internal Engine section, but seem's i have ruled out anything mechanical, so wondering if i can get some input here...here's my problem;
4 weeks ago my SS developed a vibration...since then I've replaced my underdrive pulley and flywheel (both needed replacing) and i still have this vibration. so externally there can't be anything causing this vibration..
This vibration occurs throughout the whole rpm range, both as the revs up and down. Under load is when you really get this harsh vibration ( but still present at in neutural), it causes the shifter to rattle , its that bad, not smooth at all. But the engine isn't missing, but sounds muffled from 1800 -to 3000 rpm, still seems to pull fairly good, and idles fine. Hasn' thrown any codes.
Any idea from you guys whats happening here?
Could this be electronic?
I'm lost and frustrated.

Balancer tight?
Take the belts off, and see what you get. That will at least eliminate the accessories.
What did the clutch look like when you had it out? [does the C/F have the "sliding" wts on it?]
Pilot brg good?
Does it vibrate if you hold the clutch in?
Ft brg in the trans OK?
Crank endplay is?
