Vibration

[Butcher]

Looking for some help here I've got a 1982 Chevy c-10 put 350 with 350 turbo in it. Have vibration while idling and while accelerating. Changed out tires and got balanced. Could not be driveshaft when not moving in park, checked belts and pulleys and fan. Clueless need help or ideas

check your flexplate, any ticking noise, seen cracked flex plates create a vibration

Check balancer and torque converter.

Agree about the balancer. Also check your motor mounts, they could be cracked or totally shot and you would feel vibration.

My gearhead buddy checked out my engine a month ago and revved it and said yeah, there is def. a vibration there. He suggested replace the harmonic Balancer, which is an $80-100 part and requires some serious pulley-pulling tools. "Wait! Are you saying that if my engine feels unbalanced, a part called a BALANCER might be the problem?" "Yeah." "No F***in WAY!"
