Fair question and I agree, which is why I posted this thread. Maybe his aluminum engine and heads were just within the capabilities of this fan and radiator, coupled with a much less harsh environment in Michigan versus Texas. In other words, maybe the cast iron engine and heads, coupled with the temps here, are a tad too much for the cooling system.
I am not arguing against there being something wrong with the engine, but I have far more data supporting an airflow/cooling system capacity issue than I do an internal engine issue. The engine was properly tested, machined and rebuilt and it performed flawlessly on the dyno. There are no combustion gases in the coolant, no coolant in the
oil, I was present when the head gaskets were mounted, so on and so forth. It warms up normally.
Oil pressure and temps are good and no matter how hard I run it, it stays cool. I ran the piss out of it yesterday afternoon and it was 95*F here with 50% humidity. It never got over 85*C while moving.
