So I am trying to deside on a cam for my 302 and have narrowed it down to 2 cams the xe270hr or the xe276hr which a both retro fit. The specs are the same except for the duration and overlap. The 270 will give me a small bit more torque in the low and mid and the larger will give me more mid and top horse power. The only thing is we are talking 5+,- either way in the numbers. So I know the 276 will have a lopey idle but will the 270 have any idle to it. I just need a few sound clips to get an idea. Because the sound is well worth 5 ft lbs if you know what I mean.
