If you are using the Hooker Blackheart engine mounting brackets and transmission crossmember, you won’t have any issues making the change to a 4L80 transmission. The exhaust crossover tube will sit about 1/2” behind the transmission crossmember in that installation. Post #42 in this thread depicts that fairly clearly.
