Did some research and seen a few different “methods” so I figured i should ask my friends here. Is there a proper way to break in a roller motor? I don’t think it needs the whole 20 min at 2500 deal. I’ve read on google searches that you can start it let it warm up to operating temp rev it a couple times to 3000 and shut it down? Is there any real method to break in a roller motor?

Is some truth to that.
Breaking in the rings.
Verify and correct any leaks.
Set timing.
Check lash.
 
The tradition of breaking in the camshaft is not a concern but you still have to seat the piston rings. There are a few opinions on this. One favors driving the car hard to force the rings out against the walls to establish their seating process. Another one favors a moderate application of throttle, gradually increasing over a 500 mile time frame.

I’ve heard the moderate throttle for 500 miles before, never the WOT THEORY
 
Warm it up, set the timing and recheck the lash. Take it out and put some load on it. Running in the garage doesn’t do anything for it.

I hear some crazy stuff sometimes, think about if it were going on a dyno. It would get warmed up, with a lite load on it. Everything checks out ok and the oil/water temps are up you start making pulls.

I always liked the coast down 4-5 times to seat the rings from about 50mph down to 20 also.
 
Even with a roller I'd prelube the motor by spinning the oil pump.
 
I always find it amazing the crap(ideas) we all forget when trying to formulate answers to questions. Come back the next day & look at follow ups & bang your head( I knew that, why didn't I say that?)
 
We always put them on the dyno, with basic setup adjustments. We warm them up[and dyno water supply], check for issues, then restart with a couple small tugs. After checking valve-lash...we start pulling the hell out of them, while changing timing and carb jetting. Usually, within 6-10 full pulls...we've got what we want. Last time at Muscle-Motors....

Broken in 3 motors in my lifetime. Motor 1 was babied and in less than a year I had leaking rings, motor 2 was done by the "get on the throttle" a little and let it delcel, a bunch of times, that motor is still running good. And my 3rd motor was literally set timing, check for leaks and off the dyno it went, got all the AFR's correct and made a few pulls to red line. That motor still runs awesome to this day, that was 6 years ago.
 
I always took a back roads 200-250 mile road trip (but not 200 miles away from home) with moderate throttle, then turned round and hammered it on the 200-250 mile return trip.
 
Gave it the endurance test 1st with 3car shows,the rumblers show was a 70 round trip with lots of bumper to bumper traffic.

When it passed the test it was off to the track for a weekend of drag racing starting at 9.8s at 140 mph down to 9.3's at 147.
It was still trailing a little on the decell..............
 
The Roller deal itself, IMO, don't need diddly other than normal thermal stabilization for V/train geometry check and V/Spring continuity....

But with todays cylinder wall finishes ? (no more fm SSOU50 Oil Rings)
and at track ? Best guess here....
2X Part Throttle low rpm UPshifts followed by decels
2X 3/4 throttle bursts mid rpm UPshifts with decels
2X WOT bursts....but still mid/upper rpm UPshifts with decels
then,
let 'r buck I guess ?

just say'in.... on the Dyno, we're seeing a part throttle load and unload as highly beneficial to patent sealing, then working UP through the rpm range with increasing throttle load and decel until we get there. Easeee-peazeee in the controlled environment, probably harder at the track these days though ?
