You didn't happen to re-use the I6's flywheel/flexplate did you?

If you used the 6 cylinder flywheel/flexplate on a V8 it's going to vibrate! The 240/300 inline 6's are internally balanced. That means the balancers and flywheels are zero imbalance. They are neutrally balanced, no offest counter weight. The V8's are externally balanced. The small block are either 28oz. imabalance or 50oz. imbalance. depending on the age of and size of the engine.
So if you are running a 300 flywheel on a v8 the V8 is out of balance. You will need to get the correct weighted flywheel for your engine!
