Ford 460 V8 Water Pump Failures???

My parents have a 1988 motor home with a Ford 460 V8 in it. They drive it regularly to avoid typical component failures from sitting parked too much.
However, they are about to replace the water pump for the 3rd time. They have been told that Ford 460 V8's are known for "eating" water pumps. Is it true that Ford 460 V8's are known for "eating" water pumps? If so, why are
Ford 460 V8's known for "eating" water pumps? If so, what can be done to make a new water pump last in a Ford 460 V8?

I suspect that Ford tried cutting corners on waterpump bearings during the 80s. A co-worker had an 84 302 that ate water pumps like they were

For one thing don't put too much pressure on the bearing when adjusting the belt. That was the primary cause of pump failures on those engines. Secondly don't buy a rebuilt pump, get a new pump.

We had an 88 class A with a 460 bought new. Early on there was a slight leak from the water pump. I put some Barsleak in it, never had a problem with it over 13 years. It helps to change coolant every couple of years.

You don't say what chassis their 88 was on. If it is a John Deere exhaust manifolds warping is a bigger factor. Headers will make it run much cooler and possibly avoid a cracked head.
