My engine vibrates pretty bad, i had the all the bearings done with new piston rings. When i put the engine back in i used new engine mounts, old ones were pretty bad. then i put a new dual friction centerforce clutch had my hayes flywheel resurfaced. Got my car running and it seemed like their was some vibration in drivetrain when i took off in first hard, or at higher rpms in any gear, so i did my 500mile break in, changed the rubber tranny mount with a new energy sus. mount. Started the car and drove it, it shakes and vibrates pretty noticably and bad. It does it while it idles to, and when you put the clutch in it doesn't go away, my balancer seemed a little woobbly so i put a new one on, no good. Check spark,timing, everthing checked out okay,what could this problem be, it was never there before. Engine shop said the engine looked like it had been balanced before, also looked at flwheel/clutch through inspection plate while egine running and it looked pretty smooth,same with balancer, could this be normal with stiff mounts? it doesn't seem right, Maybe valves aren't adjusted it seems to idle pretyy smooth, (while looking at it, not sitting in car) any help is gREat.
