look no hands

got a question on mounting this 400 in my duster, this will be mostly a race car but it'll make that trip to town sometimes to car shows and to show off some lol
I have both the conversion mounts and a set of elephant ears what would be the best for this all around car

The biggest pro for the elephant ears is you can cut the mount stands off the K frame. More room for headers and working on the thing. But they are solid. If you don't mind the vibrations it will be fine.
