Okay I have Chevy 1974 with new harmonic balancer, clutch, flywheel, motor and tranny mounts and its all on correct and tuned right. But when I I'm in neutral or any gear the truck shakes and usually bad when it hit 2000 rpm. And after it smooths out and at around 4000 rpm It starts to shake again bad. I can play with the clutch a little bit and smooth it out or even make it worse. I notice the input shaft was going bad when i had the tranny out but could it really cause so much shake and at certin rpm's? Does anyone know what's going on
