400 SBC

I'm starting a 240 Z 250 GTO conversion. I purchased a 400 SBC in need of complete rebuild. I plan on 9.2 CR with Holley AL heads, four row radiator and two speed electric ford fan . My question is, will the 400 have overheating problems ? Does anyone have experience with this engine in hot locations ? Should I consider a 327 or 350 to be on the safe side.

Ditto twice on what Andrew said....

 

BTW, I had a 400sb in a 69' Chevy truck that i towed, drag raced and street raced with. It didn't overheat.

 

Drill the steam holes out, use a 400 head gasket as a template.

 

I went 10.87@122mph with a 406" no frills SB in a fairly heavy 74' Nova. Using a healthy shot of nitrous biggrin.gif

 

That same car went a stout 12.17@112mph without nitrous on 235/60/14 plain Jane radials. All this with a phase 2 chevy off road solid cam and mildly ported old double hump heads.

 

I REALLY like the 400's!
