Here was my solution to avoid stock/solid/plate mounts.
Polyurethane to dampen vibration and a captured bolt to keep the engine from going anywhere if the poly failed. That said, build at your own risk. My car is in the body shop & these are untested so they may be total crap, but I think the theory is solid. Speargun's homemade engine mounts

Under 1.4 60's would be awesome.
If I can get motivated to put my car(65GTO) back together, I would like to replace the solid mounts with a Mid plate and some "ears" on the front.I would like to use aluminum for the plates/ears and have the attachment brackets on the frame welded on. Any suggestions? Other mods are 5,000rpm 8"COAN, little bigger cam and 200lb diet.

The more power you make the more stress you exert on the block at motor mount pad. Just saying. At least run a front plate.

Why couldn't you run a front plate and mid plate and use a solid motor mount as a limiter?
Either a solid mount on one side or both sides.

Does anyone else use a limiter on both sides? I just have one on the passenger side and thought that was sufficient.

Hi Jack! Thought if I got involved in posting it would probably get the juices flowing.
Now, back to the thread!
