Breaking in a race engine?

you have broke in the cam now you need to seat the rings. I like to go just fast enough it wont lung in third and then pull up to about 60 then back again, do that three or 4 times and your ready for the track

Yep.

Babying the rings at break in is an old wives tale.

I must be an old wife then , but I learned long ago that you want to seat the rings in acceleration and deceleration for a motor that will see street time.
It takes less than five minutes and I have never had oiling or compression problems in any of the motors I have done this with.
Three or four trips up to highway speed and let off to roughly half that speed...........firm but not flat footed back to 65-70.
Then flog the **** out of it.
This has been my recipe and has worked for neigh on a decade in one motor and several years in others that ran well when I got rid of them.
At a minimum , I sure didn't hurt anything by doing it. :burnout:
