Part 2: Troubleshooting overheating prob

Afternoon ...Overview (95 Camaro Z28 automatic)* Car never had overheating probs - then, from one minute to the next,overheats.* Replaced thermostat (w/Stant SuperStat Heavy-Duty 180 degree) andradiator cap.* Replaced water pump (I deduced it went bad, replaced with genuine ACDelco unit)* Replaced water temperature sensor (one located on water pump).* "Water hose" flushed engine - hose in thermostat housing, water outlower-radiator hose* Water hose flushed radiator from filler neck to lower outlet* Water hose flushed radiator from lower outlet up out filler neck("reverse flush")* "Water hose" reverse flushed engine - water hose in lower rad hoseup out water pump."Primed" engine with coolant (Dex-Cool) before installing thermostat.Installed thermostat and housing. Filled radiator with coolant andwater (50/50). I did notice that the manual calls for 15 quarts, butI couldn't even get 2 gallons worth of coolant/water mix (8 quarts -almost half what's called for) in the engine and radiator (about aquart left in the container).So I start the car up, confident that replacing the water pump,thermostat, radiator cap, a flush, and new 50/50 coolant mix will putme back on the road. (I also bled the system at the bleeder valves).No go. As the car is warming up (within 5 minutes), the temperaturegauge gets to where it normally rests, then continues to climb upwardsto red.For a moment, the gauge does begin to drop slightly, and I figure it'sgoing to continue to drop back to its normal resting point. But thenit begins to rise towards red and I shut the engine off.The in-dash temperature gauge's lower mark is 160, upper mark (top ofred) is 260 and three marks between (1/4 (185), 1/2 (210), and 3/4(235) - i'm guessing). The red begins about 1/2 way between the 3/4mark and the top mark. Historically, the gauge normally rests aroundthe 1/4 mark (185). It now climbs to the 3/4 (235) before, which isjust shy of the lower-red mark, before I shut the engine off.Any ideas what I can...
