Hey fellas, I picked up my 78 2WD Suburban today and the truck is all original and I am only the second owner. The truck has a 454/400 combo and when I took down the highway bringing it home just an hour ago it had a terrible vibration. I vibrates from about 25-30 and up. I know the 454 is extenally balanced and was wondering if it could be someone put the wrong flywheel in it. The motor doesn't vibrate when in park and reved up. It is the original motor tranny combo. Could it be a driveshaft?? I am going to dig into it more tomorrow. Any hellp or ideas would be great guys. Thanks alot.
