I converted a 82 Buick Estate from a 350 diesel to a 455 Olds. The fuel problem isn't a big one; just try to drain the tank and flush the lines. A little bit of diesel will just make your first tankful a little smoky. As for the brake booster, you can keep your hydro unit if it works well. GM actually installed a few hydroboost units in gasoline vehicles- supposedly they provide more brake boost. The only reason I ended up eventually switching my to vacuum boost was that when the booster went out, it cost about 3 times as much a the vacuum unit.
