It sounds like it runs pretty good now. My cam is a custom grind from Dwayne Porter in my street car and it sorta close to the MP .590 but its ground for my combo. Which my 63 weighs over 3700 lbs and I run a full exh but its specs are 264 & 270 @ .050 with .585 & .592 lift with a 110 LSA. I have it in the eng on a 106 ICL. But your cars runs pretty well now.
