i have not done this but have seen it so yes.
Yes.
The 94 intake hits the firewall so as is the engine will not fit. However the intake from 97-98 Mark VIIIs are different and will fit in a mustang engine bay. All you have to do is swap a 97 or 98 Mark VIII intake onto your 94 long block and it will fit. Now there is one other problem and that is that the Mark VIII engine is a modular engine so you will need a front k-member from a 96-04 mustang so that the motor mounts on the k-member line up with the ones on the engine. Any k-member from a 96-04 mustang will work even if it is from a v6 mustang.
If I remember correctly, back where the engine connects to the transmission
Passenger side of the engine.
Yes
Facing the engine, low left side of the engine .
the Lincoln mark viii is rear wheel drive and the conti is front wheel drive so to answer your question... no they will not interchange, but many engine parts will
Passenger side back of the engine
No
No
Yes!!! Actually it is not specifically designed for a mark viii (that i know of) there is one for a mustang cobra, which has the exact same 4.6L 32valve engine and will bolt right on. Search yahoo or google for a mustang cobra supercharger (Or just a 4.6L DOHC engine)
Under the engine passenger side toward the back of the engine
