i know that there have always been overheating problems with 400 sbc, well thats what i have been told, and i have also been told that it would be best to get a 4 core radiator, i am wondering if i could get away with a 3 core aluminum with a dual fan setup? im looking at making 450 hp and there will be no a/c condenser in front of the radiator. do you guys think that would work just as good as a 4 core? thanks Ty.

 

400s aren't any harder to cool than any other SBC of the same output.

 

so if i went with a aluminum 3 core with dual fan i should have no problems with keeping it cool, as long as everything is setup how it should be?

 

I wouldn't expect it to be a problem.

 

ive got a 80 over 350 3 core radiator never over heated got to about 200 one time but it was about 98 out. ive only got one electric fan on it. i really dont c a problem with yours. buddy of mine has a pontiac 400 had a little problem he told me he found a 145 termstat and put in it never gets over 160

 

ok sounds good thanks guys

 

200 is "hot", but not overheated yet.

 

yeah if it does it again ill put on another fan or go to 4 core

 

Are you running stock fan control?

 

i actually have mine wired that it comes on when u turn key something i havent gotten around to fixin yet and the more i do to this car the more im findin wrong from prev. owner. put a radio in it( they cut harness out) and that was a mess to
