Re: School me on '61 409s and L89 Novas, please!
Hylton,
One thing comes to mind: The engines were considerably "over-square", with a 4 5/16" bore. Those huge pistons weighed in at just under 2lbs ea. so the engine was rpm limited. It never did that well in NASCAR with sustained high rpm use, or on the drag strip in '64. The MK-II (mystery motor) design showed it's tremendous potential in '63, and that engine morphed into the MK-IV. (I still like the '09s though  )Verne
