I got a quick question regarding gear drives, so I figured I would post it here, I am building a 37 pontiac with a 350 chevy, I was thinking of running with a gear drive set up, I read the last thread with the guys talking about the pros and cons of them, but I heard that they sometimes cause problems with the cam cracking due to the vibration coming through the gears?? Is that true? Or is that only on real beefy engines?

Thanks, Jack
