Years ago when we ran boxstock our engine builder told us a well seasoned Cool Bore was a better block to start with then a Steel Bore.
Being it was Dave Turner who told it to us and our cool bore always seemed to run better then the Steel Bore, I always accepted it. I'm sitting here in the morning reading on bob's about engines and fuel and the question about it came back to me.
If a Cool Bore is a better block to start with then a Steel Bore, why is it so?
My thoughts were always it had to do with a more even engine expansion rate of a Cool Bore. Or maybe a seasoned Cool Bore held oil better on the cylinder walls, providing a slight performance advantage. Those are my two best guesses.
