List,
thanks to all who take the time and interest to answer my (probably) silly,
but nonetheless "important to me" questions. My engine was rebuilt about
1000 miles ago, and hopefully fully "run-in". I have a mild cam shaft in,
Petronix, and an electric fan in addition to the mechanical one (gets hot
here in South Fla.). When accelerating through the gears, when I get to
about 4500 rpms, I'm forced to change up because of a significant vibration
that causes the whole front end to perceivably shake. Is this a case of "I
should have had the engine balanced when being rebuilt" or is there an easier
answer (solid engine mounts, for example, if they even exist)? I was really
looking forward to seeing the other side of 5000 rpms....
Thanks and Regards
Geoff
