318 Bored .60 over...possible overheating?

very good answers here , with some great advice .

When you say that the radiator is specified for a '70 Plymouth "B" Body with a 318 , what exactly does that entail ? Is it a stock 22" - 26" width ? Is the motor a '70 & later with the aluminum water pump / right-side lower hose arrangement ?

Personally , I'm not a "fan" of Flex Fans , nor do I care for direct-drive fans . IMO , go for the 7-blade fan / fan clutch setup from Direct Connection ( or whatever they're called this year ... ) , and add a factory shroud from a , in this case , 1970 "B" Body .
