March sells a pulley that works with the Fluidamper. Doty Mfg also has one that should work.

Andy.......... i am trying to get as close to your 470 inch build HP and TQ numbers as possible with a Street Roller cam... At this time Larry Smith is porting my TF 240 heads and intake , which i expect this month ... Getting back to the Harmonic balancer ... I need your Expertise in this area .. should i go with ATI or FLuidampner ... The reason i ask , i do not want to run into problem with pulley alignment .. if you can tell which balancer to buy and which pulleys to use would be GREAT ..
Fluid damper ( p/n 720311 ) , which Doty p/n pulley ? and use a stock water pump pulley ?
