I put a 1953 car 235 in place of my truck's original 216 with little issue. Like you said the biggest deal was drilling the front motor mounts. I bent up new oil lines to go with the 'manifold hung' oil canister. Also, beware, the vacuum advance on a car is slightly different than a truck (on the car it points more toward the right front tire to avoid the passenger side car motor mount). I say that because I bent up all these nice lines then the vacuum advance went bad. When I replaced it, I had to replumb the fuel line and vacuum advance line to fit the correct truck setup. As tcelderman alluded to, you may have other issues if its a later 235 with the water pump, etc. Others on here can guide you accordingly. Good luck!
