bad BREAK-IN? In my haynes it says to take the vehicle from 30mph -> 50mph -> 30mph x12 times to fully seat the rings.
It says to drive the vehicle gently (no sustained high speeds) for the first 500miles. I've also heard not to take it over like 2500 rpms.
This is what I did so far:
I was having trouble with my tranny! LoL
I couldnt get it out of 1st gear! My shifter cable is messed up or something!
So I took it down my street like x15 times going from max of 3000rpms back down to 2000rpms.
Will this hurt it??????????????????????????????????
I've also heard of hard break-ins where the owner drives it like he stole it because he is gonna run high boost and he wants to break it in the same way he drives it. (i think this is stupid)

This is teh way I've always been told how to break it in. Ya know, if its gonna break it will probably be now more likely than later. I have seen many cars break in the rings in in the staging lanes/burnout box.
On another note, a good friend of mine broke the motor in on his 67 chevy pickup, and he *****-footed it for the first 500 miles. 6 months later, his ring seal went to ****.
too late for you, but...

My engine builder breaks in his engines by planting them up against a pole and burning the tires off the car. They run good too

Rings seal in the first 20 minutes.
Use break in oil (non synth), After start up, let it reach operating temps, fill radiator full, rev a few times till red line without hitting rev limiter 5>6K, then do 2>3 heat cycles. Change oil again.
Worked for me so far, my latest 370 doesn't burn a drop of oil. LME all the way
After 500 miles or so, change oil to your favorite.

whats LME? ah, i got it, the engine seller obviously
I used 5w-30 for cold start protection, but some people are saying I should've stuck to 10w-30.
So I should let it cool all the way down(0F) then heat it back up(210F) about x3 times?
So if I have already ran it 20 minutes then the rings wont seat anymore? and they are already broke in?

""""""""What about "heat cycling" the engine ??
There is no need to "heat cycle" a new engine. The term "heat cycle" comes from the idea that the new engine components are being "heat treated" as the engine is run. Heat treating the metal parts is a very different process, and it's already done at the factory before the engines are assembled. The temperatures required for heat treating are much higher than an engine will ever reach during operation.
The idea of breaking the engine in using "heat cycles" is a myth that came from the misunderstanding of the concept of "heat treating"."""""""""
