A "forty over" 350 comes up to 356.87969783762493847340748650196 cubic inches with simple calculations. Forty over shouldn't be a problem unless you have a marginal cooling system or are using it for duty that a small block is too small for anyway. (like towing heavy loads in the mountains)
Steve thanks for the info and quick answer I bought a new 4 row tube radiator for it last year and it will take the hottest heat you can actually see when the thermostat open and closes.. I ordered the motor -w- special steel head gaskets and flat top pistons 9.0-1 comp and a r.v. grind cam? that's what they told me I want this primarily for towing and fuel economy thanks again batw
