Opinions on harmonic balancers.. When do you think its time to upgrade, from the stock style harmonic balancer, to something like a Fluidampr?? Or is there another kind, that you should upgrade to that I'm not aware of?? What do you guys think?

Problem with the stockers is that they aren't keyed, pinned, or staked to the crank. They are kind of a interference fit item. Put enough torque to them with extra stuff on the front drive or dragging, and they'll slip. I'm not really sure of what the official avalanche point is with them.. if there actually is one. I have an Innovations West unit I picked up. I'm not going to advocate them only because I haven't mounted it and put the **** to it yet and I can't really take it apart to see what makes it tick. So I can't really say that it is any better built (from a performance and durability standpoint) than a stocker. I purchased it because I needed an 8 rib unit to drive my blower and it is keyed as well. It IS pretty though..
I would say if you dump the clutch, drag, or are running any extra stuff off your front drive, a "staked on" balancer is a good idea. Fluid Damprs are plain out cool anyhow.

The LT1 crank does have a keyway in it, the stock pulley doesn't. So, yes, the factory simply goes with the interference fit.
I have one of the "original" Fluidamprs, and all I had to do, in order to use it, was put a "key" in the crank. If you're worried about an OE pulley slipping on the crank, Golen Engine Service can broach a notch in your stock pulley for a nominal charge.

Its a REAL good idea from a "preventing problems down the line" standpoint. Most of the centrifugal blower kits either come with a keyed crank pulley or a "pinning kit". This because they realize that it is eventually going to be a problem down the line, if not right off the bat.
