my oil pump went out and theres a good amount of damage on the lower end, luckily i have a warranty so i might be getting a new engine, i was wondering what would be a good amount of time or mileage to break in a new ls1? i want everything to set well

 

..ttt

 

Some say put 1k on it, some say just to heat cycle it a few times and let it rip, its gonna depend on the builder !

 

i was thinking between 500-1k miles, i want the valves and springs to seat right, not sure whos gonna build it, the warranty company decides
