8 bolt crank flange

What was the crank originally for?

It's probably the same as the Hemi but the early V8's had 8 bolt flanges and I believe the bolt pattern is different than the Hemi so double check before buying and parts.

The Crank is for a 340, internally balanced, and it is an older Mopar Performance crank. This 8 bolt flange has an offset to it, Where the Hemi 8 bolt seems like it doesn't from the thread I followed to the one on E-Bay. I believe I found a mopar perf. flywheel thru Mancini, but it is steel and 30 + lb.s. I was hoping to find more options. If anyone knows other mfg. out there, let me know, Or if anyone has one for sale I am looking. I am posting pix of the Crank.
