I bought a '96 Chevy Tahoe a year and a half ago and the dealer said not =
to worry about it, but the manual DOES give a break in period of 500 =
miles and says "no towing!". It's probably not a big concern, but piston =
rings and valves aren't all THAT different from 50 years ago really. The =
Tahoe's 350 V-8 has been around how long? I figure if your gonna shell =
out that much loot, even for a rebuild, why tempt fate and end up with =
something breaking at 5000 rpm?

Subject: Engine break in
Question of the day...After an engine rebuild why do we practice
the ancient ritual of the dreaded BREAK IN PEROID? It used to be that =
when
you bought a new car and drove it off the showroom floor you had to =
break
it in. Today you pick up the car and off you go 60 miles an hour. Do any
of the manufactures still require a break in peroid?
I know what the books say about this (they actually don't say much
if you really read them) some even give a schedule to follow after a
rebuild. I suspect however that this information is being carried over
from when this was required by the industry. Unless the companies that
produce the replacement parts have a stock of old metal that they melt
down
I can't see any difference between a rebuilt engine and a new one. Parts
is parts. Now if the new car companies still require a break in peroid
then thats another story.=20
