Don't get me wrong on the idle. I love a lumpy cam but the one in the motor now is just way too much. At 15 to 1800 RPM it's still rumpty rump. Car idle's like a pro stock. I'm guessing the cam is around 525 lift and over 300 duration. I'm not looking for a smooth idle like grand pa's car. I want a good tire frier that i can still have the power brake's.
