"Bullet nose" harmonic balancer questions.

[OriginalDart]

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.

balancer does one thing, dampen harmonics (and balance an external balanced motor, oops, thats 2) I would inspect the rubber and thats about all you could do. Plenty of good SFI balancers out there, but not many have the counter mass to balance a cast crank external balanced motor. You are going to rebalance with those lighter pistons so you could internally balance and run any aftermarket damper but be careful, going to a neutral balancer will require some serious tungsten in the crank to balance it out.

You can substitute it with one from a cast crank 400.
Same amount of balance weight in the same place, but with a bunch less mass

U can sorta use the 400 dampener if u don't want ur 440 crank to last. There is a reason the 440 balancer is that thuck. Kim
