Hi Guys,

Need some of your sage advice to help me solve an overheating problem. I have a 496 stroker with a Hughes 237* cam and 10:1 CR, eddie heads and headers in my 4200lb C-body. I was running a 24oo stall converter and 3:23 gears.

All was well until I lost a cam lobe to my laziness of oil maintenance. Anyway, rebuilt the motor with a slightly smaller cam (233*) but added a 3200 stall converter and 3:55 gears. The car seriously overheated to the point of pegging the needle and boiling over. This happened within 3 hours on the new motor. I also broke a lifter and had to pull the motor for a redo cleanup, new lifters, etc. Put it back in the car and ran it. I also had my radiator rodded out and installed a new 180* thermostat. Now the car idles at about 190* and runs under mild load at about 195. When I get on it the temp goes to about 200-205*.

My thoughts: The engine did not overheat with the 2400 stall converter.
The radiator is now in better condition to cool the motor.
I have a large factory trans cooler.
Using a factory shroud and clutch fan.

I think the problem is the 3200 stall converter in the 4200 lb car does not work for me and i should go back to the 2400 stall converter.

What are your thoughts?
