seems like every other month an overheating problem thread pops up. what`s with that? how about a 327, .060 over, that`s right, .060 over, stock radiator, stock pump, no shroud not over heating. how about a 350, .030 over, stock pump, a replacement radiator, aluminum, off e-bay, no shroud, idleing in my driveway, 178, 180, all afternoon. these are my cars. man, all these "desert coolers" out there and they are working on the highway, not in town, shrouds that have solved the problem, pushers, pullers, high-flow pumps, high-flo thermostats, GEEZ! where does it end?

Unfortunately, I have one in the shop that just won't run cool. I've done and changed just about everything on this one and it still overheats setting in the drive way at idle after a half an hour.

Here's the specs as I have them:
396 Bored .010 over stock cam (timing at 8 Advanced)
Stock manifolds
Edlebrock carb
Tuff stuff 30% high flow water pump
7.6" crank pulley, 6" water pump pulley.
165 degree thermostat
new aluminum 4 core radiator
50/50 antifreeze with added wetter water
16" pusher fan in front of the radiator
had the 19" flex fan behind the radiator with a shroud till the fan flexed too much under torque and bit the radiator. (Now out being repaired)

Highway was 200 steady
Idle in the drive way after 20-30 minutes 210-220-230-240- and climbing till it gets shut off.

Even the Radiator specialists are stumped by this one.

It's not just flow. It's got to do with static too. Too much hump in the pump and you can cavatate the pump. Oversized rad...you can cool the water better in the rad. Need to find out how much flow is going through the engine...gpm. Check the specs.

I didn't know what I had until I put the gauges on. Found out I didn't need boost fan. Break it down.

to much "hump in the pump" ? you mean flowing to fast? geez, a new 4 row radiator. what about a stock pump with the flex fan?
