Vibration at certain RPMs...
I have a little vibration at certain RPMs when I rev the engine. I have hear the L98s were a little rough due to how the cams were. It doesnt feel like anything is going to go on it, but if something is out of balance (like maybe the flywheel?) I would like to fix it....Anyone have any thoughts on what it could be?

Re: Vibration at certain RPMs... (amswak)
The first thing I would do is see if it has spun. Check the timming with a light and give it a good look..Yes they will make noise if they are rubbing on something. As for the cost I spent $200 on my balancer. But that is with my new motor. You should be able to get one from GM for around $50
