[crazy longhorn]

I read the document....my guess is that their eng mount kit offsets just a tick to the pass side, & they have you do the same with the trans mounting? If in doubt, call Holley tech....I would I do agree, that in a "perfect" world the lines should be parallel so as the engine/trans are not cocked in the frame. The engine/trans can be off center....or the rear diff can be off center (and it is)! I agree with you, that if you were to hang a laser on the trans, & one on the pinion....the lines need to be parallel. The offset, the u joints will handle. In the real world, many guys will ask why? Was it that close from the factory? Also a little thought.....after she runs for a while on those rubber or poly mounts, where does it all sit then....just questions to think about If you talk with Holley tech, relay back....I can always learn a new trick.
