Mentally the turbo set up would be the easiest but I am not super familiar with supercharging in general to be honest. One thing that does concern me are the rods. They are crazy long (which to means mean prone to flexing) however they are forged but they have an oiling hole that runs from the big end to the piston pin. Packard guys seem to swear that it is essential to keep the engine from catastrophic failure but even with the tall cylinders I don't feel that it is and an aftermarket rod could be made to work. Any thoughts?

PS CNC-Dude love the signature!
