Hot Rod Magazine recently celebrated the 50th anniversary of the big block Chevrolet Mark IV engine with a world-exclusive dyno test of one of the 427 Mystery Motors built by Smokey Yunick.

The 427 Mark II Mystery Motor isn’t actually part of the legendary Mark IV family, which debuted in 1965, but you can definitely consider it the missing link between the 348/409 and big-block Chevy engine families since it has characteristics from both.
