how to break-in race motor at the track?
Im almost ready to break-in my motor and start dialing it in. I am just curious though, what is the proper way to break in a race motor while its in the car at the drag strip? I want to get the rings set properly without scuffing the cylinders to death.
its the engine in my sig... 418 sbc, full roller, forged bottom end, high lift cam, planning on running valvoline vr1 20/50 oil
does this sound right:
prime oiling system
in garage start it, bring it to 3000rpm, shut down, check for leaks.
trailer it to track
first run make a slow run keeping rpms around 3000rpm with minimal throttle
second run same thing
third run slowly raise rpm in each gear (1st-3k, 2nd 3.5k, 3rd-4k) then decelerate at the end of the track in the same fasion with the engine. (engine brake from 4k-3k)
fourth run same thing
after this I am not sure how much I should push a new engine, should I keep raising the rpm and throttle until I am doing full throttle runs or should I stop at a certain point and drive it on the street for a few hundred miles before my first full throttle run?
thanks for your help. 8)
