A street engine should be driven moderately for the first thousand miles, as follows:
· full throttle high torque power useage should be limited and never be used until the engine has
been running for at least 15 minutes.
· from 0-500 miles, do not exceed 4000 rpm.
· from 500-1000, do not exceed 6000 rpm.
· over 1000 miles, no restrictions.
Also, do not run at the same speed for extended periods during break-in. Make certain the
engine is operating at proper coolant temperature and oil pressure. Do not allow the engine to
overheat. Make necessary changes if required (radiator, fan, tuning) to get the engine to run in
the proper temperature range. We also recommend you do not run synthetic oil until at least
5000 miles. Synthetics work so well that the engine will never break in properly if it is used too soon.
