Invader was originally campaigned by Collin Mullan and Reuben Johnson powered by (we think)
a small block Chevy motor. The car was then passed onto Carlyle and Martin, calling it Black Night, before Herb Andrews got hold of it and then Kenny Coleman. It was eventually broken up in around 1980-1981. There's more info here.
