I think Strange needs to come up with a bolt in S60 and driveshaft package. If you haven't been under a new Challenger the drivetrain looks like it belongs in a Volkswagon.
The same differential has been used under the heavier and more powerful S65/CL65/SL65 cars for many years. Granted, they have auto transmissions but if 735 lb/ft in a 4800+ lb car won't break them they stand a good chance in a HC.
Some of those guys have built the cars to crank out more than 900 lb/ft and launch on slicks without lunching the diff.
The driveshaft and axles are not going to last under that abuse but that's kinda expected, don't you think?
