small block cams

Unless you have a higher compression motor I wouldn't recommend the XE268. I'm running 9.5 comp. 318 with the XE268 and its just right at the limit of what will work with my stock torque converter. With that cam on a stock 318 I'm pretty sure you won't be happy. Dog off the line and idling problems. There are some smaller cams in the XE line that would be a lot better for a stock 318. Like the 262 or 256 cam. I had to have my carb and timing just right to keep my car from dying at every stoplight.
