motor rebuild break in period

Any general rules I should follow as far as a "break in" period for a rebuilt motor? '89 300TE Str8 six. Mechanic said not over 50 mph for 5 or 6 days, try not to drive distances over 10 or 15 miles at a time. Motor completely rebuilt top to bottom. 225000 miles.

Do it slow and easy for the first few 100 miles. Don't push the engine just yet, especially not when not warmed up yet.
Mechanic sounds a bit exagerated to me. If the rebuild is performed well, driving it 'normal' shouldn't give any problems.
I'd say don't push it much over 3500rpm, don't do very long distance highway travels, let it warm up nicely, etc.
You know, just treat it nicely and it will be nice to you for a long time to come.
