hi, im currently building a 357 and need 2 know what to do for a harmonic balancer.

my specs are

2500-6500 RPM
10.3 compression
Forged eagle full floating rods (5.7)
Forged eagle crank


what harmonic balancer should i get? size? brand? what if i just get a decent stock one and send it in with everything else when i get everything rebalanced?
