an idea of making a 340 look like a hemi

i was messing around in the garage tonight and i have an old set of 354 hemi valve covers... they just about fit over a 340 mopar valve cover... some trimming on the back would make them fit good.

id be able to run the wires down through the valve covers and when all was said and done the hemi valve cover would cover the view of headers, spark plugs, be able to hide the oil fill and pvc under the dummy covers as well. ill weld studs to the steel 340 covers so i have some way to attach the hemi covers...

has any one done this... or think its a cool idea. I figured at a quick look be pretty cool
