Greg,

I used stock small block mounts that I got from Autozone. However, due to the torque twisting of the engine, one of them began to separate at the rubber. Some guys drill through both plates and the rubber and insert a bolt with washers & nuts.

I found a set of poly mounts from prothane and they are designed to not separate due to torque twisting. Thay ran me about a hundred bucks. Their site is prothane.com
