Performance upgrades advice

I have an 86 W126 420 and I want to squeeze as much power out of the current motor w/o doing anything too crazy. A guy with an 89 put an electric fan in his in place of the belt driven one. Could I do this to my car? If so, which fan would I have to use and how hard would it be to install? Also, the stock exhaust looks very restrictive and beginning to look kinda bad. I was thinking about cutting it off right behind the manifolds and having a brand new stainless exhaust made with aftermarket high flow cat and muffler (minus those 2 center mufflers). These two things should give me a decent amount of power right? What do you guys think??
