Default Solid, rubber or poly engine mounts??

I'm planning on getting new engine mounts when installing my new engine (as soon as I get it)... I wonder what the best type of engine mounts would be for a radical solid roller small block... I don't think that solid mounts would be a good idea because of the vibration transfer from the engine to the frame etc...
What would be the best mounts for such application??

Oliver, I went w/ Energy suspenion Poly mounts on my BB. They told me they had the strength of a solid but without the vibrations. I'm pleased w/ mine.

I used the Energy suspension poly mounts with my ZZ4 swap and have been pleased with the results.

Me too. The Korean-made rubber driver-side replacement didn't go 3000 miles.

What's the part number for the Energy Suspension Mounts? Are they locking?

I replaced just the drivers side with poly and could not feel a diff but the eng barely moves now, before I could see it torq aways over when driving without the hood. I wanted to keep one rubber one to help absorb the vibes and it seems the driver side is usually the first mount to go so I put the poly on that side.

I used Moroso solid mounts for the engine and trans. Love to feel that big cam hit. Plus with the lack of space with big headers and 3" exhaust, I didn't want things moving around.

502,

what is the proper part # for the solid engine mounts? I have energy susp. ones but want to get rid of them since I am running only a urethane trans mount and solid mid mounts.

Personally I LIKE my rubber GM made locking mounts. It's cool to see the engine shake with the hood off...

BTW

If you are mixing mounts make sure your trans mount is at least as flexable as your motor mounts meaning don't use a solid trans mount with poly or rubber motor mounts or you can tear the trans apart but you can use a rubber trans mount with solid or poly motor mounts.

I agree with everyone above.

After ripping three stock rubber mounts in half with a 190hp stock 1976 L48 motor. I went with Engery Suspension Poly motor mounts a few years ago and have never looked back. I recommend them highly.

looks like I'm going to go with the poly mounts.. I have rubber mounts right now with my 465+ HP Solid Cammed Stroker and made 60 passes on the drag strip and drove 12000 miles on the street and never had any issues with the engine mounts...

Good question.

I would have thought with Olie's motor he would have to do the solids.

Glad the poly's work. Ill keep that in mine. you know. that stock L82 has a ton of torque

Well - I'll still check around to see what would be best with such radical engine..

I autocross, road race and drag race. I did not have good luck with the rubber motor mounts. Drag racing ripped two of the mounts but I'm guessing the autocrossing wore them out.

Racing = finding the weakest part

I have a new motor going in later this summer. I am going to reuse the Engery Suspension units. Get black, they look like stock units.

Don't really care about the stock look... There's nothing stock on my car
