Engine runs hot at highway speed.

I know this topic has been beat to death. I have research this site and read a lot about the subject.

I have a big block 460 ford crate motor that has just been broke in. I have Dakota Digital gauges and in town under 30 mph w/electric fans running the temp moves between 195 and 210. As soon as I take it out on the highway, (55mph) the temps quickly begins to rise to 225. Last night going up the hill to a car show ( 1000 ft elevation) the temp quickly hit 231. Once I came back down the hill the temp still wanted to stay at 218. I was hard to keep running at a stop light. Can you give me a list from first to last of things to check and what might be the problem.

Electric fuel pump
750 holley carb
gear drive
cobra jet heads
Aluminum Radiator from BeCool
MSD electronic Ignition
Cool Flex hoses



I need help so I do not ruin this motor.

Thanks
Kirk
