Feel like it’s time to perform the next upgrade or two to my ‘72 Charger this Winter. Looking for thoughts.

Options:
1. Torq Storm style super charger
2. Turbo charger (could the space in front of the radiator core support be utilized?)
3. From 3.55 gears to 3.91 (rear end now is a narrowed 8.25 with rear drum brakes)
4. Rear disc brake conversion (not sure if this can be done to an 8.25
5. FiTech fuel injection (currently Mr. Gasket electric fuel pump)

Engine is 9.5:1, 5.9 Magnum, full roller, carbureted with a Quick Fuel
Trans is a fairly new 5 speed Tremec
Pro touring style look
Has A/C (upgraded Sanden short compressor), PS, PB
It is a street car. I bought it 11 years ago in its factory 318, AT, bench seat anemic state. I have been slowly working on giving it performance and attitude.
