V8 or Slant 6 K Member???

this appears to be a V8, perch measures the correct 3 3/4”, but the pass side looks to set further back than the drivers side.

Any one care to confirm it’s is a V8?

Have an upcoming Gen III Hemi swap coming up and was going to use this as a doner to mock up ahead of pulling my current K out. But then, the way I understand it, the slant 6 would be a better suiter as it affords a slight bit more room so may abandon this one in search of a /6, just thought I would confirm my suspicions 1st....
