Many HP MoPar cranks (like the 3.79" stroke) had an 8-bolt Hemi pattern flange for compatibility/strength.

Thanks. I don't know squat about these old Chrysler products. I was heavily into vintage Nissan / Datsun stuff. Sold all that and purchased a 68 barracuda. Datsun stuff got way too expensive, so I went to MoPar. Makes sense. LOL.
