The 385-series engine blocks are some 4" longer than a 351C. So it is not a drop-in swap. Done one way, a good part of the front of the engine will protrude inside the drivers compartment with you. Done another way, the powertrain is moved backward to compensate for the longer block. Either way, all you need is billet motor mounts & trans mounts, custom headers and exhausts, rework the gearshift shaft to miss the wider block and bigger, fatter header tubes, a different bellhousing, etc, etc. When you're done, 1st (and maybe 2nd) gear will be all but useless, unless you regear your ZF to compensate for the monstrous increase in torque. Adding SVO alloy heads & intake will remove all but about 50 lbs of the extra engine weight, or you'll probably need stronger rear springs and the shocks set on stiff to compensate for the wt. of the 429/460. Good luck...
