440 sitting crooked?

If the rear transmission crossmember is in alignment,,,,then you know that is right .
The front should measure like the Schumacher instructions read ,,or at least in the ballpark .

These engines are offset to the passenger side from the factory.
They all vary a little bit,,,,,but it should be fairly close.

Use the C measurement like the sheet reads,,,,from your pic that should be the easiest to check .
