Hello All, Not sure if I have reply to the right message, but re engines running on the hot side for water temp. Also there is the issue of cavitation to do with the impeller to housing clearance I think, Also engines were designed for a wide range of temps and all the variables in the replacement parts, timing cams etc etc all have effect. My other e'mail earlier today suggested using the 300F intake gasket with blockoff for heat crossover. Maybe restricting but not eliminating this passage somehow would help some engines in hotter climates / loads. Plus the issue of finding a way to restrict the internal water bypass of the bigblock Chrysler engine. Just some ideas anyway for those running out of options ... Tony in Oz.
