657 HP with a 509 cam? Not by me!

Well that HP is good to hear. I have a .060 over 440, big valves, iron heads, roller rockers, milodon windage tray, miezere water pump, headers, just under 10:1 comp and you guessed it a Doug Herbert 509 lift cam...was trying to find the card, but it is buried in a heap of receipts somewhere. I figure it's good for 600HP then....lol
