I heard these motors used to exist. Here's the valve covers for them

Was doing a search to see if anyone fabbed up 2 piece BB vlv covers and found these were made for the elusive 440 Hemi engine.  I heard those spectaters at car shows swear they used to have one in their Mopar but paid no attention .  http://www.zzcustomfabrication.com/valvecover_pics.htm
I know it was probably honest mistake but it brought back some funny conversations.

Didn't someone make a aftermarket conversion kit to put Hemi heads on a 440?   LEON.
