Make sure the truck is thoroughly warmed up and several thermostat cycles. IMHO what happens, block/water gets up to temp. Thermo cycles, lets cool water in, hits the freeze plug, plug "shrinks" just a little, and pop! Out it goes. You can also drill a few holes in the thermostat. Also I used a water pump off of an industrial application, it had a larger pulley so it ran slower at a given RPM, trimmed the fins, never had an issue and my truck saw 5000 RPM several times.
