The Dynatech Mitymounts from 440 Source look to be the same concept and may work just as well. I was running "Magnum Mounts" before. These are the same idea, but much less expensive. I don't recommend them though, because the design transmits a lot of engine vibration noise into the frame.

3rd item down on the Schumacher link...
B,C,E-Body Small Block & B/RB Poly-Locs
'66-72 B, 66-73 C, 70-74 E Small Block & B/RB Poly-Loc Set (All engines except S6 & Hemi)
Your 440 is an RB block...
That's the ones!
The Magnum Mounts are less expensive than the other options because they are stock mounts that have been modified with a bolt all the way through from the top plate to the bottom, but not tight against the bottom plate. The idea is that when the engine is put under load, the bolt head will snug against the bottom plate and limit how far the engine can lift, thereby preventing the rubber from over-stretching and tearing.
My problem with the Magnum Mounts is that, when the engine is sitting normally and the rubber is compressed, that bolt rests on the frame below the mount. This causes a lot of engine noise/vibration to be transmitted directly to the frame. If I was to reinstall the Magnum Mount, I would cut a square piece of thin rubber sheet and put it between the mount and the frame rail, to see if that helps.

The poly loc mounts don't seperate like the OEM ones do but they will melt if you have headers, at least with the Heddman shorties. You will need to fab a tin heat shield to protect them. They do transmit a bunch of vibration also.
