What kind of application are you useing this for? Road course? Drag racing? What kind of rpm are you going to run? Are you going to keep your serpitene belt system? Are you useing a internal or external balance crankshaft?

You'll have to go with an LT1 damper, I have the ATI and and it's working fine.

Yes it will, I have a Callies crank and used both the stock and the ATI on it. Far as I know all small block cranks noses including LT1 are the same, only difference is the aftermarket cranks have 2 keyways instead of one for the stock LT1.

For 7700 rpm or less you will have less harmonic flex with the Fluiddampner than you will with a ATI or TCI Rattler. This info was from ATI on a 355 motor they were testing. ATI's balancer ramped up peak crank flex @ 6500 rpm and then went back down to almost zero by 10,000 rpm. The Rattler was not even close to either balancers with the amount of flex it was able to absorb.
