I am running the stock 260, F4B and a 4 barrel.

I have a three core with stock tank radiator, OEM shroud, flex fan, smaller pulley, blocked horn holes and sealed bottom of rad to crossmember.

The temp (verified with infrared meter) does not go above 180 idling or at speed. I may need to go with a higher temp thermostat. Will know after this summer.

Anyway, the lower brace is still in place. It has many holes drilled in it though. I do not think it is necessary to remove it.
