Just don't over-rev, lug down, overheat or drive at a constant speed for the first 300 miles, then get the break-in oil out of there and run a high quality oil for 2,000 miles. You should still be taking it easy until everything is seated, but you can drive it pretty normal until then.

At 2,300 miles, change to a full synthetic oil and NEVER let it overheat.

A 350 is a durable, long lasting workhorse. It's one of the best engines on the road today.
