Alrught guys, I found a couple threads here on R3V, but I want to get a new one started. Since we seem to have a good deal of stroker guys here now - what is the BEST way to break in an M20 stroker engine? I personally think that the breakin for our engines are different than the new engines being made today - they're older, and clearances aren't nearly as tight. To the links!
Here are the other threads I found:

More? Let me know!
So, what's the best way? How do you guys plan on breaking in your strokers, and for those that have made them already, how did you break them in?
Here's what I'm leaning towards:
- Run Castrol GTX Dino oil 10w-40
- Do not start engine until it's ready to be driven - warm it up and bleed the coolant system.
- Drive around for about 5-10 miles, half throttle - goin up half way.
- Change oil after 20 miles
- Refill with Castrol GTX
- After that, do 3/4 throttle up to about 3/4 revs - do about 50 miles
- Then take it full throttle to half revs - do about 150 miles
- Change oil after next 100 miles
- Take it full 3/4 throttle all teh way up - do about 50 miles
- Take it full throttle all the way up - do about 50 miles
- Last change to dino oil after 200 miles
- Change over to Mobil 1 15w50 after the last 100 miles of breakin
I kinda just pulled that out of my ass - so what's the consensus? What should I follow? Drive the piss out of it, or take it easy, and raise the load and use as the miles climb?
I won't be using synthetic off the bat, that's definately for sure. But, outside of oil - how should my new motor be broken in??
