I cant seem to find any 100% solid motor mounts and I simply dont feel like spending 200$ on the others, I think I am just going to make some of my own. Can anyone give me the stock dimensions of the factory motor mounts? If no one can I will just order some and return them. They will be made out of 100% aerospace billet aluminum. If there is anyone else interested in having these let me know, I could maybe machine a couple more.
I got my Ultra mounts on eBay a loooong time ago and just installed them a month ago. I even had them shortened a 1/4" for my Maggie. They've been working like a champ so far and for 80 bucks shipped you can't go wrong.

I bought my Ultra Mounts a few years ago. Found one had split when I removed the engine. Surprisingly, the stickers stayed on the mounts. I called the number on the sticker, and got two new mounts sent to me under warranty.
I know that race cars use solid mounts or motor plates.....I wasn't sure
that the OP needed to go that radical.
I still run the original mounts, because I am concerned that the
noise/vibration transferred might become objectionable on even
These cars were meant to have some NVH to them. The hinson mounts though being poly handle power/movement and still keeps vibration transfer to a huge minimum. If you are worried about NVH, be wary about upgrading the tranny mount to poly, because that is where a lot of the NVH starts to kick in. Especially with the garbage 2 piece shaft.
The hinson poly mounts feel no different other then the engine being more planted to the road feel over stock. There is a mild VERY mild NVH increase at idle, but that is it.
To be blunt about it, stop being a little girl and buy the mounts! You'll wonder why you didn't sooner I promise you that much.
I've talked to quite a few people about this and most have said the vibration wouldn't be that bad. Plus it won't cost me anything to make. If the vibration is that bad with them, I'll buy the Poly ones. Not a huge job. I'm just ready to get my car on the road, she's been sitting to long.
