74 chevy elcamino

i have a 350 that is running a little hot and i am wondering why i have a new waterpump,fan cluch,head gaskets and byp***ed the heatercore and put in a used radeator can anyone help

 

Thermostat ok?

 

Get rid of the clutch fan and go for a flex blade and a good shroud, Also check timing....

 

so....you replaced your radiator , which was USED , and i ***ume there was a reason for that..for a radiator which is used

 

Can we ***ume the timing is properly set?
