I saw a dyno test that had the X-303 up by 5 ft/lbs of torque at the torque peak and 10 hp at the top as well. It would have been less of a difference had th B cam been run with 1.7's but the extra lift of the X cam with a decent set of heads would probably make the swap worthwhile. Personally, I'd go with something like a comp cams XE 270 HR and 1.7's (.544 lift and a split duration). This is the cam that I'm thinking of going to, the B-cam is ancient technology wise.
