I hear this all the time, but mine and others I know with 400's dont have any problem with overheating.

The only way 400s have problems with overheating is if you don't run a good rad or water pump or if you use the wrong gaskets for the heads... (YES people even the 882 heads are okay if you use the proper gasket)

I agree with TurboS10 I never had a heating problem with any 400 block. Hot on mine is when crusing Woodward and sitting still for long periods and heats way up to 195*

I just finished a 400 4-bolt for my 68 camaro, the only overheating problems I've seen were from a passenger when I stood on it, or other builders who use non-400 heads and forget to drill the lower steam holes !!!

maybe the reason i have seen the over heating problem is cause the only people ive seen with these are pushing over 500 ponies and have the block filled with concrete to the waterpump holes. thats probly the reason ive seen them over heat sorry if i offended anyone

No offense at all. The grouted block should not have problems with water temp, but oil temp. With the cylinder walls full of grout there is no place for the oil to loose its heat. An oil cooler is needed in that setup.

agree with TurboS10, and no offence taken. Its just like a few others stated, its the way the motor is put together, along with the steam holes.

For anyone looking at putting non 400 heads on a 400 block, the Super Chevy magazine that just came out has an article on how to drill steam holes in the non 400 heads.

Any reputable machine shop should be able to drill the holes for a nominal fee. If I recall, some of the holes have to be drilled at an angle not perpedicular to the head deck. It's not really something I want to be doing in my garage with a hand held drill.
