360 camshaft for 8.4:1 engine

The XE268 would be a good cam, but I wouldnt get any more aggressive. I run this in my near stock compression 318 with headers, 2500 stall, 3.21 gears, Eddie 600 carb. It has a great sound and lope and has good power. It is a little soft under 2500, but pulls very hard above that all the way to 5500 rpm. I would say either the 262 or 268, but the 268 is not much more aggressive, so go with it.
