318 Bored .60 over...possible overheating?

you could always mount one of them electric fans in front of the radiator with a fan on both sides it shouldn't get hot

I tried once with what I remember being 14" electric fans and I didn't have the room to fit them. With the water pump pulley assembly attached the fan would not fin in between the radiator and the pulleys. The engine bay originally held a slant 225 and I originally thought that there would be plenty of clearance thinking the 318 was shorter in length but apparently I was wrong.

It may have been the position I fabricated the new motor mount brackets. Because didn't the valiant come with a 318 option? or was the bay different in the later models?
