motor mounts question

So my old 67 had the biscuit style mounts (as I assume they all did) My guess is these did a better job of isolating vibration (rubber) verses the 73 style mounts I have in my car now, which as you know, are solid. Are there any mounts that provide good/better vibration isolation ? With the rougher idle cam - whole lotta shakin' going on. Thanks - just planning the next project and want a "tamer" feel and quieter, etc.
