360 Magnum, a 46RE , and a 8/34 in a 67 barracuda

I have a 58k mileage 67 Barracuda with the S6 and 904.
Problem is I live at the borders of Nevada, Arizona and Utah and St George, Utah is the closest larger city and we go from 900 ft to 2600 ft in the 30 min trip up there and even though the drivetrain ran perfect that little pea sized one barrel didnt like the altitude change. so I stripped the car to just the body and started over. How would you have done this swap?. More to come.
I dont know how to get pictures from my Samsung S8 to here. Cant seem to locate their URLS. Cant I just pick a pic and it uploads?
