wanna hear what a 350 sounds like with a thumpr cam and gear drive?

I already had the dual spring setup, so it really wasn't an issue when I had mine. I was also running the stock balancer at the time. As far as I could see, at that time, I was running a flex fan and it seemed to take more power out of the top end than anything else. Just kind of flat-lined on me in the uppers. I switched back to the clutch fan and that was gone.

Honestly, Hectre, I believe if the mesh of the gears is good, you shouldn't have to worry, as long as the metal used for the gears is good (which I wouldn't doubt).
