trebor...google those cams and you will get the dyno tests on both the comp XE262 and XE268.
They are dynode on the same motors..9.25:1 356 chev sm block,Dart heads (nice pieces)holley 750 and headers by comp cams.I think the 262 outperformed the 268 slightly in both torque and hp in this engine but they are close peaking at 348hp around 5200 rpm.
i have used the xe268 in a 9.5:1 340 and despite what comp says you will need a high stall converter at least with 3.23's
