Are you using a new cam? If not just be easy the first 500-1000 miles and you should be fine then change the oil and your done. If you have a new cam its different. Vary rpm from 1500-2500 for approx 30 min then change oil and drive easy for 500-1000 miles then change oil. At least thats what we did we did jump into some high speed for a minute or so but we didnt need to because the way the engine was built torque plate and rings. Forgot to mention the ynthetic oil thing Bad for break in very bad. especially if some of the assembly lube is still on the internal components. Dont forget to prime (oil) her before you crank her over.
