In regards to the turbo charger, it appears to be the old system developed by AK Miller for the Pantera. See page 122 of Pat Ganahl's book named "Ford Performance", published by SA Design in 1979. The round chrome gizmo attached to the carb mounting pad of the intake manifold is identical.
Mind Train also sold a turbo system for the Pantera in the 1970s. I'm not sure which was first.
In that era I would see a 351C turbo set-up and wonder to myself "who in the hell needs a turbo when the engine will make 440 bhp naturally aspirated?".
Frankly my opinion hasn't changed during the ensuing 40 years.
