need a little assistance
what thermostat are you using? lt1 is a different thermostat and is sorta backwards. man you got me stumped. what did the coolant look like outa the old radiator? getting any crud out of it or the motor at all?
I know I asked this before about the water pump, and you seemed sure, but did you look at the impellers to make absolutely sure you don't have the wrong rotation style pump on there? It sounds like you may have a cavitation problem.
