I've completely rebuilt my 99 lq4 motor. It now has all new bearings, injectors, oil pump, Summit LS truck cam and roller lifters. Switched dished pistons for flat tops and went 30 over giving me a 370 . I also got shorty headers. Im wanting to know best way to break this motor in. Which oil and how soon to change oil after first start.
