You'll like this joke, A man walking along a California beach was deep in prayer. Suddenly, the sky clouded above his head and, in a booming voice, the Lord said, "Because you have TRIED to be faithful to me in all ways, I will grant you one wish." The man said, "Build a bridge to Hawaii so I can drive over anytime I want." The Lord said, "Your request is very materialistic. Think of the enormous challenges for that kind of undertaking. The supports to the bottom of the Pacific! The concrete and steel it would take! It will nearly exhaust every natural resource I have made. I can do it, but it is hard for me to justify your desire for worldly things. Take a little more time and think of something that would honor and glorify me." The man thought about it for a long time. Finally he said, "Lord, I wish that I could understand my wife. I want to know how she feels inside, what she's thinking when she gives me the silent treatment, why she cries, what she means when she says nothing's wrong, and how I can make a woman truly happy." The Lord replied, "You want two lanes or four on that bridge?"
Leave the hot water in the radiator for a long time (something ridiculous like 3 weeks, vs 1 millisecond), it will be cooled down to ambient. Impractical but gets to my point. As long as this slower moving water didn't heat up significantly along its path in the block, there will be a good amount of heat transfer. Again use an extreme counter example like trap the water in the block of a running engine for 3 hours, there will be no more transfer of heat to the water. And a melted engine. I always enjoy a good discussion and welcome all viewpoints
Das what I'm talkin 'bout! We should all be fortunate enough to have a cooling system that can regulate water temp to within a few degrees of the t-stat rating. Even on a hot day, with the A/C running.
This is my experience with the "Nails". When I rebuild one I ALWAYS sonic test the cylinder walls for thickness, as well as the 455's have core shift, so do the "Nails". Because of the weight for the reciprocating assembly the walls need to be approx. .150" thick. Just like the 455's there are thin spots with no consistency. IF using lighter pistons & rods it still doesn't overcome the weights & some filler needs to be added. Even if the walls are marginally thicker & more consistent I still add filler to the bottom of the big freeze plugs on the side of the engine even on stock overhauls. This adds to the stability of the bottom end so that there is not as much flex which in the end will make the rebuild last longer. Now from my observations. With no filler in the block the engine has a tendency to run hotter than normal. With the filler in the block it appears to run cooler. Now we're not talking a lot of filler. The left side will take approx. 16-18ozs. to fill to the bottom of the big freeze plugs on the side. The right side will take 28-32ozs. to which I only add as much on the left. So in total we are taking away approx. one quart of coolant overall. I have talked to Dennis Manner why this is & the only thing he can tell me is since more coolant is flowing around the top where more of the heat is generated it appears to cool better. Makes sense to me. Ones that have done this also noticed no big diff. in oil temps. of maybe only 5-10*. This is all an assumption on both our parts. Back to the regulary schedould topic at hand.

This has always been a hot topic. What it all boils down to is this...you can't have too much radiator! Yes, it's too early, not enough coffee. Devon
