It is important to run ANY engine for at least 30 miles round trip at sustained hiway speeds with out shutting off the engine until the 30 miles is complete. MOST important is to allow any gassoline engine to warm up to at least 120 degrees F before any driving except for maybe backing out of the garage.

THe post war high compression engines OF ANY mfg'er need to run a sustained 70 to 100 mph for at least 30 miles on some regular basis, say once every 3 months. Especialy if the engine is subject otherwise to alot of stopping, starting or short runs.

The absolute worst possible engine operation is failure to warm up engine for at least 3 full clock minutes, stopping and starting engine every 5 to 15 minutes (local errand running), or alot of short runs at low speeds under 50 mph.

The big V8's of the 50's and later were designed for sustained hard high speed operation and therefore do not lend themsleves well to any operating environment that mite resemble Harriet Nelson shuttling the kids to school or liesurely drive thru town to Tiffany's to buy a glass mushroom sculpture nor for Ozzie to just bop over to the country club to chase a little wihite ball around.
