I own a 1957 Chevy with a pre-1969 350 cid engine. the engine has a short water pump. I want to replace it with a long water pump. Is this an easy swap? Or do I have fitment concerns? Will it bolt right up, will the fan and pulley fit the LWP? Will there be sufficient radiator clearance? I want to do this to move the alternator to the passenger side of the engine. And help, info or suggestions are appreciated. Thanks.
