The argument about the 6.2 and 6.5.
I don't recall seeing the correct spelling for gees/geez in the dictionary

Man I skipped ahead in the thread cause i couldnt wait to see this really cool project in fast fwd mode. I hate to see it given up on...even worst to land right in the middle of people dreaming the junk diesel ever made 6.2 would somehow save this project...lol. Seeing people restore a 6.2 is funny to me...after this motor the diesel world changed forever...not only Chevrolet, but every manufacturer in the world said whatever we do it can't turn out like this P.O.S. Lol
That's correct if you're relying on natural convection but in any engine system you have the coolant pump forcing the water to go where it is plumbed. Horizontal/vertical, left/right, up/down....doesn't matter. Think of it in terms of potential energy...if you have a high pressure region and a low pressure region, where does the high pressure coolant want to go? To the low pressure region...always. As the coolant cools off (becomes more dense) when it moves from high pressure to low pressure, well this change in density adds to the pressure differential already present by the inlet/outlet pressure differential presented by the water pump.Cooled coolant flows "down" much better than "up" as in the above set-up!
actually there is another reason OE's plumb their cooling systems with suction (low pressure) in the bottom of the rad and return at the top ... if it's plumbed "backward" and coolant level ever drops below the upper radiator nipple then pumping stops and the engine overheats ... so the way the camaro is plumbed above is asking for trouble unless the coolant is 100% topped off 100% of the timeThat's correct if you're relying on natural convection but in any engine system you have the coolant pump forcing the water to go where it is plumbed.

Good point Jim.actually there is another reason OE's plumb their cooling systems with suction (low pressure) in the bottom of the rad and return at the top ... if it's plumbed "backward" and coolant level ever drops below the upper radiator nipple then pumping stops and the engine overheats ... so the way the camaro is plumbed above is asking for trouble unless the coolant is 100% topped off 100% of the time
