best harmonic balancer for a 340 stroker motor around 500 hp?

I have a decent looking stock dampener on my new 414 stroker with a steel crank. Kinda scared to run it with the extra horsepower, anyone use an aftermarket with good results. #1 fitting correctly. Thanks in advance.

ATI Super Damper, Fluid Damper, Performance Rubber Damper, in that order. Depends on the budget. 440

I went with this one on my 408 on advice from other guys that have them.. went on fine and i don't have a ton of miles but no weird vibrations or anything..

OH BTW.. no honing needed (in my case) and pulleys all lined up perfectly... that's all
