The vibration is bad enough to cause the rear axle to jump and hop and I can't even get moving.
I suspect the engine mounts are bad and allowing the engine to twist and move. The clutch might need to be replaced also.
does this sound like a possible culprit. Can I buy stronger motor mounts (something that can deal with the stronger 350 motor). Is there anything else I should look at as a possible culprit.
