400 SBC heat problem?

[Disciples Performance]

hey guys

now i know the 400 sbc has a problem with overheating quite easily. Now im gonna throw a new high flow water pump into it, right away here and a thermostat. Now should that take the problem away for the most part? cause i cant see how other then those 2 ways it would overheat any other ideas?

thanks

Is your motor built?
I've got a 400 in my stock 1970 impala. Never had a heating problem. Needle sticks right at 190, even sitting in traffic on woodward for 3 hours during dream cruise. Only time I've heard of heating problems is when people bore 'em out more put power-adders on.
That said, I can't see a high-flow water pump hurting. Do you have a heating problem currently, or just trying to prevent one?

Did you just build the motor? Are the heads drilled for steam holes? If not, that's your problem right there, or maybe you used a non 400 head gasket.

What condition is the radiator in?

Do you have a stock clutch fan or an electric. If you're concerned, get an aluminum radiator with dual electric fans
