Ray, when I saw that "lump" I thought it may be covering a second engine mounted in the back, however looking at some close up photos of it , looks like he has just mounted a roof top car carrier (pod) in the bed and painted it to match the car!
There are other photos where he has an elevated engine "dyno" mounted in the bed with a Citroen motor on it.
Wierd (like everything else on this forum):lol:
