No reason why not. A/C really has nothing to do with the engine other than the compressor mounting.



Thats not entirely true...

Factory A/C cars came with an upgraded cooling
system, Including a 26" radiator core support,
26" radiator, fan shroud/ bigger fan, fan clutch,
different water pump...etc...

Did your 318 car come with factory A/C?
If it did, your slant six condensor, assuming thats from a factory A/C slant six car,
should drop right in...
