I would look at an Isky Mega cam, either hydraulic or solid. These cams are ground on 108deg. lobe center. This will you more mid range torque, perfect for a long stoke engine, and provide a really lopey idle. I would stay away from the one size fits all cams such as the Edelbrock, besides their cams mirror those of 30 years ago. If you look at gross duration and that at .050 you will see that most name brand cams are much tighter, open quicker. This will give you more effective valve lift, thus more airflow. Good luck.
