Never ran the 509 cam, though I did run the old Street Hemi grind in my 64 300, 750 carb, 4.10 gears and a stick car too. I miss that car, many a 454SS and Iroc Z got spanked with it.
How much did your '64 300 weigh? I always got a kick out of people's reactions when they got spanked by a big C body!
