    Why not rubber? Not a challenge, just wondering.

    Just what I happened to buy. The motor mounts in my Elise are poly, and the extra vibration doesn't bother me.

    If these ones rattle your teeth out mike, a stock set of rubber mounts are about $10 at your local parts store

    Big cam and poly motor mounts. I am sure it will be a very comfortable ride.

    I've got a pretty aggressive cam in my LS1 supported by polyurethane mounts and I've never noticed any vibration. I'm sure you'll be fine Mike; these engines always impress me with how smooth they operate.

    Also, as far as Dave's question, for me, it was $50 for a set of stock rubber Camaro mounts, or $60 for polyurethane mounts. Urethane it was! It's a lot different when there are hundreds of different vendors selling hundreds of aftermarket parts for your engine; lots more options!

    What are the specs on your cam again, please? In my 5.3 LS4, I am using a 224/224/.600/.600/114LSA.

    Also, I plumbed the fuel delivery system today:

    When I saw how much the LS1 mounts were I went out of my way to change the design and use cheaper SBC mounts. lol.

    It's the Lingenfelter GT11

    They highly recommend a change of your valve springs and retainers due to the high lift.

    This is combined with a set of Lingenfelter CNCLS1-C ported & polished heads with oversized 2.02"/1.57" SS valves, titanium retainers, and competition cams dual valve springs
