Hemi Question, What would you do

i was once told that during break-in... jackrabbit starts damage rings and high rpm's egg the bearings.

if you havent been doing either of those i would give it to 1000 miles. take it for rides where you can vary the speeds, accelerate and decelerate off and on. like a highway cruise.

if it's still smokin at 1000 i would send it to the builder
