67 coronet 440 .060 over, 509 cam, stock 26" rad with shroud and stock 7 blade clutch fan, 10 to 1 compression, 180 degree stat. i drove it today to town and it was about 83 degress outside. the temp guage(mechanical) just keeps climbing very slowly. by the time I got to town 200 degrees. drove home a few hours later, 210 degrees when i got home (15 miles) it hasn't boiled over yet. i have a 6 pac scoop that I thought would help with cooling but it doesn't. the carb isn't sealed to the scoop if that matters. i know the stat isn't sticking. any thoughts??

Id be looking at the fan clutch. When you shut the engine off, how long does the fan spin? How easy does it turn when hot? Do you have a spring in the lower hose? Is the rad clean?

I am truckless..

I had a problem with mine running hot on the highway. I put a spring in the lower rad hose to keep it from collapsing, and that solved the problem.

Is that stop & go/slower speeds or highway? 210 ain't terrible but it's getting there. If highway I would suspect a partly plugged rad.

TOTAL timing is what you're looking for. 12* would be the initial, but if your using a stock distributor, and pushing the initial to 12*, you could be up over 40* total, which could cause it to run hot. Find out what your total is, or just back the initial down to about 6 or 8 and see if it affects the heat issue. If not, then you have eliminated timing.

That sounds like a flow issue to me.

210 is OK, but it's a problem warning. Shouldn't be that hot if things are up to snuff.

I want my fair share

hi
yes by all means you should have a spring in the lower one and a knowen good fan clutch .

your timing curve may need recalabrated .

move your timing up to 16 inital and make dist top out at about 34-36 max .

what is your app cranking comp psi ?

hi stall convertor can also add heat , use a big trany cooler in the air streem !

That will really improve to lower your temp!
Some people have thrown these away in the past and now looking for em!

If all the good suggestions given have been tried and you are still running hot, pull the thermostat out and drive it. If it runs colder then you have a bad thermostat. I found this out after several thermostats, all bad. Be sure to order a Mr. Gasket hi-flow, about 180* from O'Reilley's. That should help the flow problem.

All of the thermostatically controlled fan clutches (the ones with the spring on the front side) I have gotten in the last several years have been factory set to lock up at 210 degrees. So basically on hot days out here that’s where my cars run (but I’ve never had one go over that as long as the clutch was good).

On a side note, if the spring on the front of the clutch is tightened (usually ½ a turn at a time), it will lower the temperature the clutch locks up).
