Harmonic Balancer

I have a '68 Mustang,but I changed the motor to a '71 302 and changed the C4 to a T5. The engine developed a clack, clack noise and when I took it apart 3 pistons are scored, so I have to replace all the pistons as well as the cam. (one lobe wore). But my question is, when I removed the harmonic balancer it is a E4TE-A3A 4 bolt, which I think is a 50 oz. On a '71 302, should it not be a 28.2oz?
Thanks

Thanks. You confirmed what I thought. Now it's which make of balancer to use. The range in price from $100 to &500. Any ideas? Have to get the stroke measured. It's a '71 302 with 351 windsor heads and the crank has M1 on it, so I think it is a 289 crank. I don't know if the rods were changed. Thanks for your help.
Now I'm trying to get the heater core out. (one of the pipes came out with the heater hose). Can you remove the clips on the heater box and split it open, or does the whole thing have to be removed. I have the nuts off on the firewall in the engine bay, but doesn't seem to move.
