I have a Mexican Fender Strat from '96, a Fender Frontman Reverb amp and a DF-7 distortion factory pedal. How do I get the tone for Back in Black, Whole Lotta Love, or Am I Evil?

So youve returned. You make me remeber me when i first bought a strat.
As I can see you only got that dist pedal, i must recommend to you a multi effects that can fit your pocket like a Digitech RP90 for $75 bucks or even a RP55 for $45 bucks if thats the case. Then youll have plenty of room for playing with tones and sounds. And if you can get a $125 bucks for a RP255 you can get plenty of presets loaded to your pedal from the usb connection.

A Strat wasn't used in any of those songs you mentioned, so don't be surprised if you cannot nail those sounds 100%. You'll get close enough though. And close enough is what rock & roll is all about, right?

There is no 'recipe' for dialing in someone else's tone with completely different gear and without their fingers. Just play around and twiddle the knobs on your amp and pedal and you'll get there. Maybe along the way you'll also discover a 'signature' tone that is all yours.

And a little tip from beginner to beginner.
Dont try to rush things up. Learn to hear it. Nothing is that easy as we think. The quest for tone is endless. And I must say that it always ends up to your fingers, not your rig.
Music theory is a wonder-world. And besides boring, I´m beggining to taste it. And its good!

I do know how to play these songs pefectly. It's just the tone thats killing me. Also I know that Back in Black and Am I Evil? were recorded with different types of guitars (SG and an ESP), but Whole Lotta Love was recorded with a Telecaster, which is not that different from a strat. Anyway thanks for the comments.

The key to those sounds was the amps.
Small wattage amps overdriven will give you the necessary distortion.
However, as far as the recorded sound approximation, ambient sound was part of the recordings, one mike up close to the amp, another in a corner or other side of the room. That gives you a perceived thicker sound.
The sound waves from the amp to the close-up mike have less distance to travel than the waves captured by the mike at the opposite end of the room, thus you get a delay in recording the same sound when played back.
This also gives the perception that the amps were huge (not So).
You cannot overdrive a 100 watt amp in a studio setting without sound bleeding thru and thus contaminating other tracks. A small amp 5, 10, 15, 20, watts can be made to sing and more importantly controlled.

Nothing is worse than going to listen to a band in a small club using colliseum spec equipment amplification. The sound man (if Any) is overwhelmed by white noise and unable to isolate the sound spectrum for max audience response ( other than running for the exits )

Also all those sounds were captured with analog equipment, bounced tracks, multilayered etc...etc...

Also keep in mind that when playing the riff of say whole lotta love, open strings are sounded to ring in unison, in a combination of sliding up to pitch and fretting the second note. Intro to whole lotta love is played on the low E , A and D strings, no bar chords

Go to Phil X's website @ frettedamericana.com he does a great video lesson of many intro's right up your alley.

Also on your strat you could install a humbucker in the bridge with a coil split switch, I have a JB player with Carvin pups ssh with the split.

Good luck and happy adventures in your sound search
