Just picked up the Sept copy of Muscle Car Review, and there is a story on the z-11's run by Frank Sanders and Terry Prince. Also an article on the 409 history and a 59 state trooper biscayne. Interesting articles...I am no expert so I am not commenting on the accuracy....I'll leave that up to you.....and sorry DQ but they refer to em as "BIG BLOCKS"....better setem straight.
