Thanks Chet, thanks for the reply,  I agree sounds like temps are ok. I have found it true about finding it's own level. good teh see you doing good with you're car

Good to hear Chet, I have had my 28 out several times over the summer, I noticed you mentioned it ran very cool.  I am kind of curious about the water temperature, I believe mine runs hotter then it should.   Have you ever measured it? I installed thermocouples in the supply and return lines closest to the block.  Mine runs about 208 to 210 deg. F leaving the block and around 120 deg. F supply.  This stays fairly consistent regardless of ambient temp. or miles traveled. I tried an antifreeze mixture and it didn't seem to want to cool properly so I went back to straight water. I am thinking the specific gravity of the coolant affects the circulation. Anyone have any experiences with this?
