I am trying to put a 5.8L 351m (with a 400 block) in my 1982 F-350. The passenger side mount will mount up. But the driver side will not go in the hole. How do I get the driver side mount to go in the hole?

The freeze plugs are spaced out in a straight line along each side of the block. If you see others at the same height in front or behind where the motor mount is, then yes it probably is a freeze plug.
Put a jack under the engine with a block of wood between the oil pan and the jack head. Raise it slightly to remove the motor mount through bolt, then remove the mount from the engine block. Now you should be able to replace the plug. Use a punch to drive in one side, then grip with pliers and pull it out. Clean the recess before installing new plug. Auto stores stock them in all dimensions, or take your old one in for matching up. The rubber expansion plugs work well, too, and easier to install.
grab a block and a jack then place jack under engine or transmission, then put pressure on it, then remove center support bracket on bottom remove mounts install new ones reinstall center bracket line up mounts in bracket tighten center bolts remove jack and block
The 1985 Impala came standard with the Chevrolet 305 V8. All Chevrolet small block V8's from 265 cubic inches to 400 cubic inches from 1957 to about 1989 used the same block with almost no difference in the castings, so the motor mounts should fit from one block to the next. If you are trying to swap in a 350 newer than 1989, then the motor mounts are different, and you will have to have them fabricated by a local welder, machine shop, or perhaps the best, a local short-track race car driver/builder. Those guys can build anything.
The 351C motors were made only for cars. The difference is on the thermostat and how it goes on the engine. The 351-400M motors went on the block and were identical motors exept for the bore( 4.00) and the stroke(crank).both 400-351 M use the big block pattern for the bellhousing The 351C uses a smallblock bellhousing pattern The 351C valve covers and heads will interchange not manifolds though.. The 351W looks like a 302 smallblock, with a higher deck height. the firing order is also different from a 302. Hope this helps.
