hey everybody,

    i have a 83 westy air-cooled, that needs a motor, one in it runs but
needs replacing,
    I found someone selling a 73 Bus, with a Brand New 1800cc engine in it,
for  $500 bucks,
    Will that engine fit exactly into my 83 vanagon,  without any mods what
so every?
    And will it make it much slower, since my Westy came with a 2000cc motor?

Thanks
Mike
