Just to add to the knowledge base with our experience:
FE's are notorious for overheating and we fought it for a long time--but no more. Make sure the harmonic balancer pulley and the water pump pulley are at a 1:1 ratio. We make custom pulleys now just for that. Originally, the waterpump is underdriven and that doesn't work so well in traffic. Next, we put a big sucker fan on the back of the radiator and ditched the front fans. Finally, we made a billet radiator tank that can be pressurized to 20 psi. We make the billet radiator tank for small blocks, big blocks FE's, 351W's, 351C's, 460's, and the monster SOHC.
No more problems.
