Default LT1 overheating

my LT1 is overheating again....only when i beat the **** outa it though....i can leave it running for 6 1/2 hrs w/o turning it off(sometimes i have to for my job) and it wont overheat. Only when i go out having fun with it does it do it(beat the **** outa it). i changed the waterpump(due to splines on the coupling being worn), thermostat, replaced all hoses and checked the radiator out and its not plugged....i am bout ready to give up on the car due to all the problems i've been having with it....
