okay, searched for this topic but couldn't really find anything to relate to:
68 camaro conv.
fresh 327 swap from a 6 cyl.
ever since i put the new engine in, there is a vibration that comes along at about 60 to 65 mph. it smooths out after that. i'm thinking it has something to do w/ rpms because when i'm warming the car up and it is idling high i can feel the vibe, but not as intense. i don't really know how to describe it, but i'll try. smooth...vibration...vibration tapers off...smooth for a second or two then does the same thing. any clues? the car didn't do this before i did the swap, i am thinking it is drivetrain related.
