Ed,  two factors are at work.  First the S-beam is longer on the left side.  The reason for this is to provide more room for the exhaust INSIDE the motor mount tubes.  On the right side, the S-beam is shorter to provide more room for a cool side radiator OUTSIDE of the motor mount tubes.    Also, at work is the right thrust angle of 1.25 degrees.  Despite the optical illusion, the engine is on the design thrust line.  Jerry

Nice work, Jerry.

 

Is it just the angle of the photo or is the pan is not aligned with the mount?  It appears cocked over to the right front of the mount pretty far or at least there appears to be a lot more front mount showing on the left side of the pan (photo reference)
