Newly Rebuilt 200 Issues

[my64falcon]

Hey guys- I have a 64 falcon that I just put a newly rebuilt 68 200ci in. It is bored .030" over, standard pistons, mild cam, over than that, everything all stock, but new. It has brand new hoses and a brand new radiator. It comes up to temperature pretty cool and then gets REALLY hot. It pegs the stock gauge (idiot light w/ a needle), but I got an infrared thermometer and measured at the thermostat housing I was getting up to like 215* before I shut it off. Timing is set at 12*. It has an electric fan with a ground sided temp switch installed in the thermostat housing. The fan works fine, although part of me is wondering if I need to either get another fan or a better one that pushes a little more air. It is mounted on the front drivers side of the radiator pushing. Depending on what you guys think, I may try to get my hands on a box fan to put in front of the car and see if my problem goes away. If it does, then obviously it's an issue with my fan. Thanks for the help guys!!!

' put a '71 MAverick 170 in a '61., and used the larger Maverick radiator for year with no problem. When the 250 performance six was put in the '61, immediately ran HOT, to finish static run-in on cam and gather parts, running a water hose lightly over radiator immediately cooled down to normal temps. Installed generic aluminum radiator on mod' rad support with high-cfm fan with thermostat housing switch - like you mention. No problems after many miles.

Box fan is a good idea or cold water stream should determine if radiator is the problem,

New engines may be a little "Tight" , even a fresh OEM radiator may be just - sufficient, but mild engine should be no problem. Alternate radiators, some bolt-in are available but think simple - is thermostat backwards?, hose bent?, ....

Think simple - is thermostat backwards?, hose bent

Start simple then work up to more complex. Thermostat in backwards has driven many a man while till they found it.

thanks for the ideas guys. it should not be a radiator issue since it's a brand new radiator. I will check the thermostat first just in case some how I made that mistake. if thats it, i will be very impressed with myself.... but I will be happy if thats all it is.

Back-flush the block. Stick one of those hose-thread thingies on a heater hose, disconnect the lower radiator hose at the radiator, connect the garden hose, turn it on and catch the outflow. You will be amazed at what flows out. You can blow out the radiator backward too.

i don't think that flushing the block or radiator will help at all. freshly rebuilt engine. block was thoroughly hot-tanked and cleaned and radiator is brand new

Any Proggress?

Actually, I just installed a freshly rebuilt engine and a ton of crud came out and clogged my rad. it was running way hot and I couldn't figure out why. I ended up installing an aluminum rad, which fixed the problem, but when I inspected the old rad it was totally clogged. The hot tanking, etc can loosen stuff up that finally lets go when you start driving and clogs the rad. try backflushing before you spend any money.
