"Bullet nose" harmonic balancer questions.

My block is a 78 440 from a van/rv . I pulled a build sheet from hotrod.com and am going for 5-550 horsepower. It's a budget build so my bottom end is stock with the exception of some kb hyperuetech pistols and a comp cams xe285hl cam. Im ready to reinstall the balancer and my questions are:
Is the stock "Bullet nose" (external balance) harmonic balancer capable of handling that power?

If not, what brand of balancers should I be looking for? I'd rather go for quality over price.

Thanks for the help mopar family.
