gran torino- Pinging

i have a 1972 ford gran torino, which i have recently purchased ,it has a 351clevland 2bbl which seems to be pinging under load, it seems to be running quite hot as well, i have heard that maybe removing the air con equipment may help it to run cooler, then also i guess it may be that the timing is out , so any help on this matter would be much appreciated, thanks:confused:

Those were in the early era of pollution controls and have several little devices that could affect it. I think it has an egr,they are used to cool combustion temps,might check that it's functioning. If it is the plate type,the early aluminum ones had a bad deterioration problem and would errode away creating a lean condirion that would also cause that.
