will this cam fit it 318

From the link you posted, a partial quote:

======================================================
"top-end horsepower is desired. These camshafts are designed to take advantage of the latest improvements in valve train components and the newest developments in camshaft design. Their aggressive lobe design produces better throttle response and top end horsepower than other cams with the same duration @ .050'' lift, while delivering increased engine vacuum. We do not recommend the use of stock valve train components with these camshafts due to the aggressive lobe designs."

This says to me this is not a mild street cam

There is a hell of a lot of info in that catalog about heading down the correct path
