I hate posting about this again, but...........
As you know, the typical parts store BB mounts don't last long. However, I need to put a passenger mount in my old beat up Imperial.
I Work at Advance auto in Glenside, PA. Nearby is a garage called Montgomery's. His Dad was a famous drag racer. My complaint is that there are only two kinds of 2250 mounts- $5 mounts and $200 mounts from schumacher or Bouchillon. He says that there are in between mounts made now. Anyone know what Im talking about?

If you're replacing the PASSENGER side mount, then pretty much any one should be fine. That side is under compression when you are accelerating, so little chance that the rubber will separate unless you like doing burnouts in reverse.
I purchased a blowout-proof mount for the drivers side that was already modded similar to the one in the link that Vucelick linked to. The mount I got used 1 bolt instead of 2, and the mod in the link shows drilling through both the mount itself AND the metal bracket that attaches it to the engine block, but it will work the same. I think I bought it from Mancini. It was about half the price of Schumacher. After receiving it, my first thought was "This is just a modified parts store mount. I could've done this myself!"
With this mount, I always felt vibration on the steering wheel EXCEPT when accelerating. When the rubber compresses due to the weight of the engine, the bolt head extends down and rests on the frame and transmits engine vibration. This was obvious when I later removed the engine and saw clean steel on the frame where the bolt head rested. If attempting this mod (or buying this style of blowout-proof mount), I would try putting a piece of thin rubber sheet below the mount to try to prevent the vibration.
When reinstalling the engine, replaced the mounts with Schumacher Poly-Locs. To anyone getting Schumacher mounts, note that they use a frame attachment bolt that is larger diameter than stock mounts. On one side this fit fine for me, but the other side had a clearance problem and I had to get a drill in to open the hole in the frame more. This was a PITA because the mount was already attached to the engine and the engine was hanging on the hoist in the engine bay. If you're installing Schumacher mounts, test-fit them to the frame before attaching to the engine if possible!

Mike66Chryslers, My passenger motor mount is broken too. It doesn't get as much of a beating as the drivers mount, but I need it to be as strong as the driver's side for rocking in snow and knowing I can give it some throttle in reverse without breaking my shroud.
