Sorry, I have no idea, I just thought I had seen it was 260 @ .50 and was going to tell you no way that would work. I know the cam specs there will work with your 305, but im not familiar with a 305 and not sure how it would act or perform.

If that's the hi energy 260 comp cam, it's a pretty mild cam. I've never tried one on a 305 but I've noticed that other 305 guys are using larger cams without too much trouble.
It seems like it should work.
