It is a 4 door Plymouth Fury. I'm guessing it is a 74 or 75. This car and the "Test Tube T' won Steve Tansy the ISCA "Builder of the Year Award".
I don't where it was raced. I have been searching the internet for more info on Mr. Tansy. If you go to:

And do a search for him you will see at least one of the Funny Cars he drove.
Both pictures of the Kop Kar came from the same book. The book is called "Showtime - The Story of the International Championship Auto Shows and the Hot Rod/Custom Car World. A Twenty Year History". It was written by Michael Sheridan and Sam Bushala. Published by Promotional Displays, Inc. Copyright 1980. isbn 0-87358-278-0. IT IS AN AWESOME BOOK!!!
BTW - Mr. Tansy also built a car that had a 100 year old Brunswick, Blake and collender pool table as part of the car. It was called "The Pool Hustler". He also built the "Vending Machine" that used a Coke Machine as part of the cab.
