Quick engine position question

The Chrysler has 1 3/16" pinion offset. The 8.8 usually has 1/2". You'll be off by 11/16" if you just weld the perches on. It depends on the rear if you have enough tube on the left side to narrow it properly. If it can be narrowed to fit properly you'll need new axles at least. Compound pinion angles will probably cause harmonics of some sort. On the other hand, using a rear with the pinion in the wrong place is done all the time.
