how hot does it get between the block and the cylinder heads,ie like for the headgaskets?not in the combustion chamber itself but between or around the bores?

 

My guess would be a bit higher than your coolant temp. Maybe about 250?

 

wondering since the combustion chamber gets much hotter

 

I thought you meant block temp, then reread your question. Why do you want to know? This is a heat and mass transfer question, and I'm a couple semesters away from it. I do know that the CC can get upwards of 2500F. At this point you get some NOx, or oxides of nitrogen. We have EGR to cut down on NOx.

To know you'd have to know the surface area, specific heat of the aluminum, and the iron sleeves, and probly some other stuff I don't even know about.

Where's Old SStroker?

 

i dont need to know necessarily IN the chamber but its pretty darn close to it since its between bores and between the head and the block.im just running somethings through my head and need to know how hot it would get there and assuming u get a good clamp on the heads is there ANY gases or coolant that gets there

 

You're worried about boiling coolant? the water is moving pretty quick, I couldn't imagine it would stay in one spot long enough to boil or cause problems.
