Harmonic Balancer question

#1
I am getting ready to order my balancer. Just wanted to double check with you guys which is the correct one. I see the 6-1/4" is for the 348 and 409 Low Performance engine. There is also a 6-3/4" for hi-po engines. I have 656 truck engine and would assume I need the 6-1/4". Thanks in advance guys.

The 6 1/4 will be fine,BUT most of the new ones are 8-10 degrees off on the TDC markings.Easy fix ,just remark either the balancer or timing tab.
