Are there different harmonic balancers for 429/460

Does the 429/460 have only one balancer available? Or is there a 3 and 4 bolt like the small block. If so when were each used?

The FRPP units have both ..3 and 4 bolt patterns.

The very old 429 engines and maybe also the 460 had a balancer with belt grooves cut into it's circumference. It was made similar to a 300 6 cylinder balancer in that way. The spacer used behind it is also unique. After about 1970 they changed and I think that they are all the same.

Doesn't the Ford racing piece have two patterns so that it can also be used on an FE engine?

my ford steel balancer has dual bolt pattern
