RE: Interesting Question

John, very interesting information on sodium filled exhaust valves. Thanks for sharing.

I can remember the sodium filled exhaust valves being used in heavy duty Ford trucks with FT engines. This evidently was done for the cooling of the exhaust valve because a dump truck engine is not known for high RPMs. Under a low RPM strain that a huge load of gravel could put on a dump truck engine, the exhaust valve sees some extreme heat. Guess Fords race engineers saw some advantages to both heat transfer and lighter weight when it came to the exhaust valves. They must not have forseen the damage these valves can do after sitting for years without being used.
This thread, so far...
