I agree!!!
Any engine can run hot. Lack of cooling system maintenance can cause problems with any engine, a 400 included.
SBC 400's are awesome engines!!! I've seen several run for years, zero cooling issues. I have one slated for my 67 C-10 LWB, can't wait to get that thing going!!!
I HAVE heard of folks with SBC 400 cooling issues, the end problems had nothing to do with the fact that the engine was a 400...........
