Hey Ron! I ran against a (Vauxhall) Chevette with a V12 Jag engine in the '60s. It had fuel injection and the stacks were tall and at different angles like a, oh, Kinsler maybe? I can't quite remember but whoever made the stacks they were a big name in mechanical fuel injection for drag racing at the time (and probably still are) and famous for these tall stacks. Definitely used on a Jag V12 though - circa 1985.
